Sales Enrich

Enrich Contacts & Clean CRM Data

Help the user enrich contacts and companies with verified data, clean stale CRM records, and optimize their enrichment workflow. This skill is platform-agnostic but references Apollo.io as the primary tool. The same strategies apply to ZoomInfo, Clay, Lusha, Cognism, or any enrichment provider.

Step 1 — Gather context

If references/learnings.md exists, read it first for accumulated knowledge.

Ask the user:

1. What do you need to do?

• A) Enrich a list of contacts with emails/phones
• B) Enrich company/account records with firmographic data
• C) Clean up stale or incomplete CRM data
• D) Set up ongoing auto-enrichment
• E) Deduplicate contacts or accounts
• F) Verify existing email addresses before a campaign
• G) Other — describe it

2. How many records are involved?

• A) Under 100 (manual/one-time)
• B) 100-1,000 (batch job)
• C) 1,000-10,000 (bulk operation)
• D) 10,000+ (large-scale cleanup)
• E) Ongoing (continuous enrichment of new records)

3. What enrichment tool(s) do you have?

• A) Apollo.io
• B) ZoomInfo
• C) Clay
• D) Lusha / Cognism
• E) Clearbit / Breeze
• F) Multiple providers (waterfall)
• G) None yet — recommend one

4. What data do you need?

• A) Email addresses (verified/deliverable)
• B) Phone numbers (direct/mobile)
• C) Both email and phone
• D) Firmographic data (company size, revenue, industry, tech stack)
• E) All of the above

Step 2 — Enrichment strategy

Choose the right approach based on volume and frequency:

Single-record enrichment

• When: Researching a specific prospect, manual prospecting
• How: Look up individual records in your enrichment tool or via API
• Credit cost: 1 credit per person (email), more for phone numbers
• Best for: High-value ABM targets, executive-level contacts

Batch enrichment

• When: Enriching a list before launching a campaign
• How: Upload CSV or select records in-platform for bulk enrichment
• Credit cost: 1 credit per record enriched (plan carefully)
• Best for: Campaign prep, list cleaning before outreach

Auto-enrichment

• When: Keeping CRM data fresh continuously
• How: Set up rules to enrich new records on creation or on a schedule
• Credit cost: Ongoing — budget credits monthly
• Best for: Teams with steady lead flow who need data quality without manual effort

Waterfall enrichment

• When: Single provider doesn't have enough coverage
• How: Try Provider A first → if no result, try Provider B → then Provider C
• Credit cost: Only pay for successful enrichments at each level
• Best for: Maximizing coverage when targeting niche personas or international contacts
• Key waterfall providers:

For detailed per-provider workflows, API endpoints, and credit economics, see references/platforms.md

Step 3 — Execute the enrichment

Pre-enrichment checklist

• [ ] Deduplicate first: Remove duplicate records before enriching — don't pay to enrich the same person twice
• [ ] Filter to qualified records only: Don't enrich contacts you'll never reach out to
• [ ] Check existing data: Skip records that already have verified emails/phones
• [ ] Estimate credit cost: Records × credit cost per record. Stay within budget.
• [ ] Set enrichment scope: Choose which fields to enrich (email only is cheaper than email + phone + firmographic)

For platform-specific enrichment workflows, API endpoints, credit economics, and bulk operation instructions, see references/platforms.md.

Compliance checklist

Before enriching and contacting, verify compliance with data privacy regulations in your target regions:

EU contacts (GDPR):

• [ ] You have a lawful basis for processing (legitimate interest for B2B outreach is common, but document it)
• [ ] Your enrichment provider has a GDPR-compliant data sourcing policy (check their DPA)
• [ ] You can honor right to erasure requests — if someone asks to be deleted, you can remove them from all systems
• [ ] Your outreach includes a clear way to opt out
• [ ] You're not enriching personal data beyond what's necessary (data minimization principle)

US contacts (CAN-SPAM):

• [ ] Every email includes a physical mailing address
• [ ] Every email includes a working unsubscribe link
• [ ] Unsubscribe requests are honored within 10 business days
• [ ] Subject lines are not deceptive
• [ ] The email is identified as an advertisement (if applicable)

California contacts (CCPA/CPRA):

• [ ] You provide a "Do Not Sell My Personal Information" option if applicable
• [ ] You can disclose what personal data you've collected if a consumer requests it
• [ ] Your enrichment vendor's data collection practices comply with CCPA

General rules:

• If someone unsubscribes, suppress them globally — don't re-enrich and re-add them next month
• If you're enriching contacts in bulk, check regional distribution first and apply the strictest relevant regulation
• Keep a log of where enriched data came from (which provider, when) for audit purposes

Data quality scoring

After enrichment, score your data quality:

Step 4 — CRM data hygiene

For stale data identification, deduplication strategy, enrichment schedules, and ongoing data quality automation, use /sales-data-hygiene. That skill covers record matching, merge rules, audit trails, and refresh cadences in detail.

Key rule: Always deduplicate before enriching — don't pay to enrich the same person twice.

Step 5 — Credit optimization

Credit-saving strategies

• Enrich only qualified records: Apply ICP filters before enriching — don't waste credits on bad-fit contacts
• Check existing data first: Skip records that already have the data you need
• Prioritize email over phone: Email credits are typically cheaper. Only reveal phone numbers for contacts you'll actually call.
• Use waterfall strategically: Start with the cheapest provider, escalate to premium for high-value targets
• Batch over real-time: Bulk enrichment is often more credit-efficient than one-at-a-time
• Monitor usage weekly: Set up alerts when you hit 80% of monthly credit budget

For platform-specific credit economics, see the relevant platform skill (/sales-apollo, /sales-zoominfo, /sales-clay, etc.) or references/platforms.md.

Gotchas

• Don't enrich before deduplicating. Claude often recommends "enrich everything, then clean up." This wastes credits on duplicate records. Always dedup first, then enrich the clean list.
• Don't assume enriched emails are deliverable. Enrichment tools find email addresses — they don't guarantee deliverability. Always run enriched emails through a verification tool (NeverBounce, ZeroBounce, MillionVerifier) before high-volume campaigns. Apollo-reported "verified" emails still bounce at 5-10% rates.
• Don't enrich an entire CRM database at once. Claude tends to suggest bulk-enriching everything. This burns through credits fast and enriches records you may never contact. Start with your highest-priority segments and expand.
• Don't ignore phone number credit costs. Mobile number reveals are 5-10x more expensive than email reveals in most tools. Only reveal phone numbers for contacts your team will actually call — not the entire list.
• Don't set up auto-enrichment without a credit budget cap. Auto-enrichment can burn through an entire month's credits in days if configured too broadly. Set a monthly cap and limit auto-enrichment to new records matching your ICP.
• Don't enrich contacts without checking regional compliance. Enriching EU contacts without a lawful basis for processing (GDPR), or emailing US contacts without an unsubscribe link (CAN-SPAM), exposes you to legal risk. See the compliance checklist in Step 3 before enriching in bulk.

• Self-improving: If you discover something not covered here, append it to references/learnings.md with today's date.

Before recommending a specific platform skill

This skill covers a strategy domain across many platforms. Before pointing the user to any specific platform skill (any /sales-{platform} listed in ## Related skills, e.g., /sales-mailshake, /sales-klaviyo, /sales-apollo), read that platform skill's actual SKILL.md first. The 1-line description in ## Related skills is enough to identify a candidate — it's not enough to commit to it or to write a prompt that invokes it well.

How to read it:

• If ~/.claude/skills/{skill-name}/SKILL.md exists locally, Read it.
• For sales-* skills, WebFetch directly from this repo: https://raw.githubusercontent.com/sales-skills/sales/main/skills/{skill-name}/SKILL.md — e.g., for sales-mailshake: https://raw.githubusercontent.com/sales-skills/sales/main/skills/sales-mailshake/SKILL.md.
• For non-sales-* skills (third-party), look up {org}/{repo} in ~/.claude/skills/sales-do/references/skill-sources.md if installed and fetch the same skills/{skill-name}/SKILL.md path under that repo.

After reading, ground your recommendation in something concrete from the SKILL.md (its scope, a sub-flow, its argument-hint shape, or a "Do NOT use for..." negative trigger). Align any generated invocation with the platform skill's argument-hint. If the platform skill turns out not to fit the user's situation, swap to another or handle the question here directly rather than recommending a poor fit.

Examples

Example 1: Pre-campaign enrichment

User says: "I have 500 contacts for a campaign but only 60% have emails. Enrich the rest." Skill does: 1. Recommends deduping the list first 2. Filters to records missing emails 3. Sets up batch enrichment in Apollo with email-only scope (save phone credits) 4. Recommends email verification before launching the sequence Result: List enriched to 85%+ email coverage, verified and ready for outreach

Example 2: CRM data cleanup

User says: "Our Salesforce has 50,000 contacts but half the data is stale. Help me clean it up." Skill does: 1. Identifies stale data patterns (bounced emails, outdated titles, missing fields) 2. Recommends a phased approach: dedup → prioritize top segments → enrich in batches 3. Sets up an ongoing enrichment schedule to prevent future staleness 4. Calculates credit budget for the cleanup Result: Phased CRM hygiene plan with credit-conscious enrichment strategy

Troubleshooting

Low enrichment match rate

Cause: Prospects are in niche industries, use uncommon email domains, or are very senior (C-suite data is harder to find) Solution: Try waterfall enrichment across multiple providers. For C-suite, try LinkedIn manual lookup or ask for referral introductions instead of cold outreach.

Enriched emails bouncing

Cause: Data provider has stale records, or person recently changed jobs Solution: Run enriched emails through a dedicated verification service before sending. Set up a feedback loop — when emails bounce, re-enrich or remove the contact.

Credits running out mid-month

Cause: Over-enrichment (enriching too many records or enriching phone numbers unnecessarily) Solution: Review usage in Settings > Usage. Restrict enrichment to ICP-qualified records only. Limit phone reveals to contacts tagged for calling. Consider upgrading plan if consistently hitting limits.

In Apollo.io

Single enrichment: Search for the person in Apollo's database → click to reveal email/phone (costs credits).

Bulk enrichment: 1. Select contacts in a list or search results 2. Click "Enrich" → choose fields to enrich 3. Apollo processes in background, results appear on records 4. Export enriched data or sync to CRM

CRM auto-enrichment: 1. Settings > Enrichment > Auto-Enrichment 2. Set rules: enrich new contacts on creation, enrich existing contacts on a schedule 3. Choose fields to enrich and credit budget per month 4. Monitor usage in Settings > Usage

API enrichment:

• POST /people/match for single-record enrichment
• POST /people/bulk_match for batch (up to 10 per call)
• GET /organizations/enrich for company enrichment
• See /sales-apollo for full API reference

In ZoomInfo

• Contact Enrich — POST /enrich/contact with name+company, email, or LinkedIn URL. Returns verified email, direct dial, title, department, seniority. Up to 25 records per API call.
• Company Enrich — POST /enrich/company with domain or company name. Returns revenue, employee count, industry, SIC/NAICS, tech stack, HQ location.
• Bulk Enrich — async batch enrichment via POST /bulk/enrich with callback URL. Use for 100+ record operations.
• Auto-Enrich — configure OperationsOS rules to enrich new CRM records on creation or on a schedule. No manual intervention needed.
• Intent Enrich — POST /enrich/intent returns active intent signals for a company plus recommended contacts. Use to prioritize which records to enrich first.
• Credit system — each enrichment consumes credits. Monitor via X-Usage-Record-Limit-Remaining header or Usage API. Professional: 5K credits/yr, Advanced: 10K, Elite: 10K + Copilot.
• Waterfall position — ZoomInfo has the broadest B2B database (260M+ contacts). Often used as the primary enrichment provider, with Apollo, Lusha, or Cognism as secondary/tertiary in a waterfall.

In Tomba

Single enrichment: Use the Email Finder (name + domain → email) or Email Enrichment (email → full profile with name, title, company, social handles, location).

Bulk enrichment: 1. Upload a list to Tomba's bulk operations (up to 10,000 records per batch) 2. Choose the operation: bulk email finder, bulk verifier, bulk enrichment, bulk phone finder 3. Use webhook_url parameter for async completion notification 4. Export enriched results or sync to CRM via Zapier/HubSpot/Salesforce integration

Domain-wide enrichment: 1. Domain Search on the target company → get all known emails with names, titles, departments, seniority 2. Filter by department and seniority to focus on decision-makers 3. Verify results with Email Verifier before sending

Email pattern detection: Use the Email Format endpoint (/v1/email-format) to discover what pattern a company uses (e.g., first.last@ at 85%). This lets you validate found emails and predict patterns for people not in the database.

API enrichment:

• GET /v1/email-finder for name+domain → email
• GET /v1/enrich for email → full profile
• GET /v1/domain-search for domain → all contacts
• GET /v1/linkedin for LinkedIn URL → email
• Auth: X-Tomba-Key + X-Tomba-Secret headers
• See /sales-tomba for full platform reference

Credit economics: Searches and verifications are separate quotas. Free plan: 25 searches + 50 verifications/month. Starter ($39/mo): 1,000 + 2,000. Phone data costs additional credits.

In Mailmo

Single enrichment: Use the Email Finder — enter first name, last name, and company domain → Mailmo returns a verified email. Every result is verified in real-time including catch-all detection. You only pay for verified emails found — no charge for misses.

Bulk verification: 1. Upload a CSV of email addresses to Mailmo's Bulk Verification 2. Mailmo processes the list with catch-all verification 3. Download results with verification status per email 4. Remove invalid addresses before importing into outbound tools

Catch-all advantage: Mailmo's key differentiator is catch-all mailbox verification. Standard verifiers mark all catch-all addresses as "risky" — Mailmo attempts to verify the specific mailbox. For lists with many catch-all domains, Mailmo provides significantly more definitive results than competitors.

LinkedIn prospecting: Use the Chrome extension on LinkedIn/Sales Navigator profiles to find verified emails with one click while browsing.

No API: Mailmo does not have a public API. All operations are through the web UI or Chrome extension. Export via CSV for use in other tools.

Credit economics: 1 credit per verified email found or verified. No charge for misses or duplicate searches. Credits roll over month-to-month. Free plan: 50/mo. Starter ($9/mo): 500. Professional ($39/mo): 2,500.

In Hunter.io

Single enrichment: Use Email Finder (first name + last name + domain → email with confidence score and verification status). Or use Domain Search to find all emails at a company, filtered by department and seniority.

Bulk enrichment: 1. Use the Bulk Email Finder API — submit an array of name+domain pairs 2. Hunter processes asynchronously — check job status via GET /email-finder/bulk/{id} 3. Verify found emails with Bulk Email Verifier before sending 4. Export results or push to CRM via HubSpot/Salesforce/Pipedrive integration

Domain-wide enrichment: 1. Domain Search on the target company → get all known emails with names, titles, departments, seniority, and confidence scores 2. Filter by department (executive, sales, engineering, etc.) and seniority to focus on decision-makers 3. Hunter also returns the company's email pattern (e.g., {first}@domain.com) — use it to predict emails for people not in the database 4. Verify results with Email Verifier before sending

Technographic prospecting: Use TechLookup to find companies using a specific technology, then Domain Search each to find contacts. Use Discover to filter companies by industry, size, and location.

API enrichment:

• GET /domain-search for domain → all contacts
• GET /email-finder for name+domain → email
• GET /email-verifier for email → deliverability status
• Bulk endpoints available for all three operations
• Auth: api_key query parameter, X-API-KEY header, or Authorization: Bearer header
• See /sales-hunter for full platform reference

Credit economics: Domain Search (1 credit per 10 results), Email Finder (1 credit per find), Email Verifier (1 credit per verification). All share the same monthly pool. Free plan: 50 credits/mo. Starter (€34/mo): 2,000. Growth (€104/mo): 10,000. Failed lookups (no results) are free.

In Prospeo

Single enrichment: Provide name + company (website, LinkedIn, or name) or a LinkedIn URL → Prospeo returns verified email, job title, full profile, and company data. Set only_verified_email: true to only pay for records with verified emails.

Bulk enrichment: 1. Use the Bulk Enrich Person API — up to 50 records per call 2. Each record needs an identifier for tracking plus name+company or LinkedIn URL 3. Response separates matched, not_matched, and invalid_datapoints 4. Batch larger lists into groups of 50

Company enrichment: Provide a domain or LinkedIn URL → 50+ data fields including industry, employee count, funding, tech stack, revenue range, job postings, SIC/NAICS codes.

Mobile enrichment: Add enrich_mobile: true to any person enrichment — costs 10 credits instead of 1. Only enable for contacts you'll actually call.

Search-then-enrich workflow: Use Search Person (200M+ contacts, 30+ filters) to find targets, then Bulk Enrich to get contact info. Search returns profiles but NOT emails — enrichment is a separate step.

API enrichment:

• POST /enrich-person for single person enrichment
• POST /bulk-enrich-person for batch (up to 50 per call)
• POST /enrich-company for company enrichment
• POST /bulk-enrich-company for batch company enrichment
• Auth: X-KEY header
• See /sales-prospeo for full platform reference

Credit economics: 1 credit per matched person/company. 10 credits if mobile included. Free for no-match and lifetime dedup (re-enriching same record is free). Free plan: 75 credits/mo. Starter ($39/mo): 1,000.

In Seamless.AI

Single enrichment: Search for a person in Seamless.AI's Prospector (1.8B+ emails, 414M+ mobile numbers) → reveal to get verified email, phone, title, and 100+ data points. Each reveal costs 1 credit. Search/browse is free — only pay when you reveal.

Bulk enrichment (CRM Enrich): 1. Connect your CRM (Salesforce or HubSpot) via native integration 2. CRM Enrich matches existing records against Seamless.AI's database 3. Fills in missing/stale fields — emails, phones, titles, firmographics 4. Run on segments (not the entire database) to conserve credits

Autopilot enrichment: Set ICP criteria → Seamless.AI continuously finds and delivers new contacts matching your filters. Automated list building with enrichment built in.

API enrichment:

• POST /contacts/research to initiate contact enrichment (by search result IDs or direct contact data)
• GET /contacts/research/poll to check enrichment status
• POST /companies/research for company enrichment
• Async pattern — results delivered via polling or webhook
• Auth: Token: API_KEY header or Authorization: Bearer (OAuth 2.0)
• See /sales-seamless for full platform reference

Credit economics: 1 credit per contact reveal. Search/browse is free. Pro plan credits expire daily (~1,000/day/user). Free plan: 50 lifetime credits. Basic ($147/mo): 250/month.

In SafetyMails

Single enrichment (Email Finder): Enter first name, last name, and company domain → SafetyMails returns a verified corporate email. Every result is auto-verified through their 19-step algorithm. You only pay for found emails (7 credits) — risky domains cost 1 credit, not-found is free.

Bulk verification: 1. Upload a CSV/TXT list (up to 2M emails) to the SafetyMails panel 2. 19-step verification: syntax, MX, SMTP, catch-all, spamtrap, disposable (80+ services), role-based, domain typo correction 3. Download results with per-email status: Valid, Invalid, Catch-All, Disposable, Spamtrap, Role-Based, Syntax Error, Domain Error 4. Remove non-valid addresses before importing into outbound tools

Real-time API (form validation): Embed JavaScript on signup forms to verify emails at point of capture. Prevents invalid addresses from entering your database — <1 second response.

No bulk enrichment API: SafetyMails bulk verification is upload-only via the panel. The real-time API is designed for single-email form validation, not programmatic batch enrichment. For API-driven bulk workflows, use SafetyMails for verification and another tool (Apollo, Hunter, Prospeo) for finding.

Credit economics: 1 credit per email verified (bulk). Email Finder: 7 credits per found email, 1 credit for risky/invalid domain, 0 if not found. Pay-as-you-go ($7.50/1,000) or subscription ($6.80/mo/1,000). Credits never expire. Free: 100 bulk + 1,000 API trial.

In Outscraper

Emails & Contacts: Pass a list of website URLs or domains to GET /emails-and-contacts — Outscraper scrapes all publicly visible email addresses, phone numbers, and social profiles from those sites. Best for extracting contact info from business websites found via Google Maps scraping.

Contacts & Leads: GET /contacts-and-leads finds up to 3 email/phone contacts per company, with support for preferred contact types. More targeted than raw email scraping — returns named individuals rather than generic addresses.

Company Insights: GET /company-insights returns firmographic data (industry, size, revenue estimates), tech stack, social profiles, and company descriptions. Use to enrich CRM records with company-level data.

Email Validation: GET /email-validator verifies email deliverability (valid/invalid/risky). Run after enrichment to clean the list before sending. Supports batch queries (up to 25 per request).

Bulk workflow: Outscraper's API supports batching (25 queries per request) and async processing with webhook callbacks. Ideal for programmatic enrichment pipelines — scrape businesses from Google Maps, then enrich with contacts and validate emails in the same workflow.

Credit economics: Pay-as-you-go, no subscriptions. Free tier: 500 Google Maps records/month. Medium: $0.002/record. Business (50K+): $0.001/record. Tiers reset every 30 days.

In Enrich.so

Reverse Email Lookup: Pass an email address to Enrich.so's API — returns the person's LinkedIn profile, job title, company, education, 50+ data points. Best for enriching CRM contacts where you have email but need full professional context.

LinkedIn Profile Enrichment: GET /v1/api/linkedin-by-url — pass a LinkedIn URL, get full profile data including positions, education, skills, contact info, network stats. Works for both person and company profiles.

Email Finder / LinkedIn to Email: Find verified business email from a LinkedIn profile URL. Supports async responses for large batches. Success-based credit model — only charged when an email is found.

Phone Number Finder: Find mobile and landline numbers from profiles or emails. Useful for phone-heavy outbound cadences.

Company Data: Company lookup by name, domain, or LinkedIn URL returns industry, size, revenue, tech stack, social profiles. Company Funding & Traffic adds investor details, funding rounds, and web traffic estimates.

Search Similar Companies: POST /v1/api/similar-companies — find lookalike companies from a LinkedIn company URL. Filter by location and employee size. Returns relevancy scores. Great for expanding target account lists from existing customers.

Search Company Employees: Find decision-makers by company and role with detailed profiles. Useful for multi-threading into target accounts.

Bulk Enrichment: POST /v1/api/bulk-enrichment — batch process via CSV upload, JSON array, or CSV URL. Supports types: person, company, find-email, mobile-finder, linkedin-to-email. Async with webhook callbacks (webhookUrl parameter). Poll GET /v1/api/bulk-enrichment-results for results.

Credit economics: Success-based model — only pay for verified data. Free: 25 credits. Starter: $59/mo. Professional: $99/mo. Scale: $149/mo. Pay-as-you-go from $20/100 credits.

In Lobstr.io (scraping-based enrichment)

• Google Maps Leads Scraper: Extract business contact data (phone, website, email, address, hours, ratings) from Google Maps listings. Not traditional enrichment — it's scraping public data, but the output is structured contact/company records you can import into CRM or outbound tools.
• LinkedIn Sales Navigator Scraper: Extract lead profiles from Sales Nav searches — names, titles, companies, LinkedIn URLs. Requires cookie-based account sync for login-wall access.

In Clearbit (Breeze Intelligence)

Person enrichment: Pass an email address to GET https://person.clearbit.com/v2/people/find?email={email} — returns 80+ attributes: name, title, role, seniority, company, social profiles (LinkedIn, Twitter, GitHub), location, bio, and more. 1 credit per successful lookup.

Company enrichment: Pass a domain to GET https://company.clearbit.com/v2/companies/find?domain={domain} — returns 100+ firmographic attributes: employee count, estimated annual revenue, tech stack, industry (SIC/NAICS codes), funding history, company type, parent company, social profiles, location.

Combined enrichment: GET https://person-stream.clearbit.com/v2/combined/find?email={email} — returns both person and company data in a single call. Use this when you need both and want to minimize requests.

Streaming vs async: Clearbit offers two modes per endpoint:

• Streaming (e.g., person-stream.clearbit.com): Holds the HTTP connection open for up to 60 seconds while data is fetched. Returns the result inline. Best for real-time form enrichment and low-latency workflows.
• Standard (e.g., person.clearbit.com): Returns 202 Accepted if data isn't immediately available, then delivers via webhook. Best for batch/background enrichment.

Name to Domain: GET https://company.clearbit.com/v1/domains/find?name={company_name} — resolve a company name to its website domain. Useful when you have company names but no domains (e.g., from event lead lists).

Prospector: GET https://prospector.clearbit.com/v1/people/search — find contacts at a company filtered by role, seniority, title, and location. Use to build contact lists at target accounts without needing names upfront.

API details:

• REST API, HTTP Basic Auth (API key as username, no password)
• Rate limit: 600 requests/minute
• Base URLs vary by API: person.clearbit.com, company.clearbit.com, prospector.clearbit.com, reveal.clearbit.com
• SDKs (Ruby, Node, Python, Go) are deprecated — use direct HTTP requests

HubSpot / Breeze Intelligence: Clearbit was acquired by HubSpot in December 2023 and is now also available as the Breeze Intelligence add-on inside HubSpot. Breeze uses a credit-based model within HubSpot. If the user is already on HubSpot, they may be able to access Clearbit enrichment natively without a separate Clearbit subscription.

Bulk workflow: Clearbit doesn't have a dedicated bulk endpoint. For batch enrichment, loop through the streaming endpoints (up to 600 req/min). Use the combined endpoint to get person + company in one call and halve your request count.

Credit economics: Clearbit pricing is volume-based and quote-driven (no public per-credit pricing). Contact sales for plans. HubSpot Breeze Intelligence: credits purchased as add-on packs within HubSpot billing.

In RB2B (Identity Resolution API)

IP-to-identity resolution: RB2B's API product (api.rb2b.com) resolves IP addresses to identity data — hashed email (HEM), LinkedIn profile URL, and company firmographics. Use for enriching website visitor data or building identity resolution into custom pipelines.

Endpoint chain for full enrichment: 1. GET /v1/ip/hem — resolve IP to hashed email (SHA256) 2. GET /v1/ip/linkedin — resolve IP directly to LinkedIn profile URL 3. GET /v1/ip/company — resolve IP to company firmographics 4. GET /v1/linkedin/email — resolve LinkedIn URL to work email 5. GET /v1/email/linkedin — resolve email to LinkedIn URL 6. GET /v1/company/firmographics — get full company data from domain

Pixel-based enrichment: The main RB2B product (pixel, not API) automatically enriches website visitors with person-level data (name, email, LinkedIn, title, company) — no manual enrichment needed. Data pushed to CRM/Slack in real-time.

API pricing: Credit-based, separate from pixel product. 1 credit per lookup. 100 credits = $9, 1,000 = $49, 10,000 = $299. No subscription required — buy credits as needed.

US-focused: Person-level resolution has highest match rates for US-based data. Company-level resolution works globally.

Best for: Enriching anonymous website traffic with identity data, building custom identity resolution pipelines, resolving IP→person→company in programmatic workflows.

In 6sense

People Enrichment API: GET/POST scribe.6sense.com/v2/people/Enrichment — pass email or name+company to get contact data including email, phone, mobile, title, seniority, job function, department, and associated company firmographics. 1 API credit per lookup.

Full Enrichment (Lead Scoring + Firmographics): GET/POST scribe.6sense.com/v2/people/full — returns everything from People Enrichment plus product scoring data and segment membership. Use when you need both contact data and 6sense intelligence in one call.

Company Identification: GET epsilon.6sense.com/v3/company/details — resolve IP addresses to company firmographics. Install via WebTag (JavaScript) on your website for automatic visitor identification, or call directly from your backend.

Segments API: GET scribe.6sense.com/v2/company/segments — check which 6sense segments a company belongs to, plus buying stage, intent scores, and profile fit score. Use for real-time personalization.

API auth: Org-level API tokens provisioned in platform settings. Multiple tokens supported for security isolation.

Credit system: API calls consume credits from plan allocation. Credit consumption varies by endpoint. Unused credits expire monthly.

Pricing note: API access requires a paid 6sense plan ($50K+/year). Free plan (50 credits/mo) gives basic search only — not full API access. Enterprise pricing makes 6sense better suited for high-volume, high-value enrichment, not one-off lookups.

Best for: Enterprise teams already using 6sense for ABM who want to enrich inbound leads with intent data and buying stage alongside contact/firmographic data. Not cost-effective as a standalone enrichment tool — use Apollo, Hunter, or Tomba for enrichment-only use cases.

In Swan

• AI-powered enrichment: Swan enriches contacts and accounts as part of autonomous GTM workflows. Describe what you need in plain English — Swan handles the data fetching using its own aggregation layer across multiple providers.
• API enrichment: POST /research/person endpoint enriches individuals with email, phone, job title, LinkedIn URL, company info, and job start date. POST /research/company answers questions about companies with confidence scoring (1-10). Base URL: https://api.orchestra.inc/v1, auth via x-api-key header.
• Credit-based: Each enrichment action costs 1 credit ($240/mo for 4,000 credits). No per-contact pricing — same cost whether enriching 1 field or all fields.
• Aggregated sources: Swan pulls from multiple data providers (Apollo, ZoomInfo, etc.) through its own layer. No need for separate subscriptions to individual providers.
• Best for: Teams wanting enrichment as part of an end-to-end GTM workflow (research → qualify → enrich → outreach) rather than standalone data lookups. For granular waterfall enrichment across many providers, Clay offers more control.
• Platform skill: /sales-swan

In Clay (Waterfall Enrichment)

• What it is: Clay aggregates 150+ data providers (Hunter, Apollo, Clearbit, People Data Labs, Dropcontact, ZoomInfo, Lusha, RocketReach, Cognism, and more) in a single waterfall workflow. Query multiple providers in sequence — if Provider A misses, Provider B tries, then C.
• Waterfall enrichment: Configure provider priority order per column (email, phone, firmographics). Use "only if empty" logic between steps to avoid burning credits. Coverage compounds — 3 providers at 60% each can yield 85-95% coverage.
• Claygent for custom enrichment: AI research agents browse the web, extract data from company pages, navigate gated content. Use for non-standard enrichment (tech stack, pricing, org charts).
• CRM sync: Bidirectional sync with Salesforce, HubSpot, Dynamics 365. Import contacts for enrichment, push enriched data back automatically. Requires Growth plan ($446+/mo).
• Credit system: Data Credits consumed per provider lookup. Different providers cost different amounts. Unused credits roll over up to 2x monthly allocation on paid plans.
• Pricing: Free (100 credits/mo), Launch ($167-185/mo, 2,500 credits), Growth ($446-495/mo, 6,000 credits), Enterprise (custom). As of March 2026 — verify current pricing.
• Best for: Teams needing maximum enrichment coverage across multiple providers with a single tool. GTM engineers building automated enrichment workflows.

In LeadMagic

• What it is: API-first B2B data enrichment with 19 REST endpoints. Pay-per-result — you only pay for valid results (not_found = free). Base URL: api.leadmagic.io, auth via X-API-Key header.
• Email Finder: Name + domain → verified work email at 97% accuracy (1 credit). Profile to Email: LinkedIn URL → work email (1-2 credits). Personal Email Finder: B2B profile → personal email (1-2 credits).
• Mobile Finder: Direct dial mobile numbers for decision-makers (5 credits per valid result).
• Company enrichment: Company Search for firmographics, technographics, and competitors (1-2 credits). Company Funding for rounds, investors, amounts (4 credits).
• Employee/Role discovery: Employee Finder at just 0.05 credits per employee for bulk discovery. Role Finder for specific titles at companies (1-2 credits).
• MCP Server: Official MCP server with all 19 tools for Claude Code, Cursor, Windsurf, VS Code — enrich directly from your editor.
• Pricing: Trial (free, 100 credits), Basic ($59.99/mo, 2,500), Essential ($99.99/mo, 10,000), Growth ($179.99/mo, 20,000), Advanced ($259.99/mo, 30,000). As of April 2026 — verify current pricing.
• Best for: Developers and GTM engineers wanting API-first enrichment with transparent per-result pricing. Excellent as a provider in Clay waterfall enrichment.

In Attio

• What it is: Attio's built-in contact and company enrichment. Basic enrichment on all plans; AI-powered enrichment on Pro ($69/seat/mo) and above.
• Auto-enrichment: New contacts and companies are automatically enriched from email addresses and domain data. Fills company name, industry, size, social profiles, and contact details.
• AI Research Agent (Pro plan): Goes beyond database lookups — researches contacts and companies from public web sources, LinkedIn, news, and more. Can create notes and update fields automatically.
• Data sources: Email metadata, domain/company databases, public web (AI agent). Not as comprehensive as dedicated enrichment tools (Apollo, ZoomInfo, Clay) but eliminates manual data entry for basic CRM fields.
• Limitations: No credit-based pay-per-enrichment model — enrichment is included but limited to Attio's data sources. No waterfall enrichment across multiple providers. Personal email addresses (Gmail, Yahoo) often don't match.
• Best for: Teams using Attio as primary CRM who want automatic record enrichment without adding a separate tool. For deeper enrichment needs (mobile numbers, technographics, intent data), pair with Apollo, Clay, or ZoomInfo.

In BrandJet

• 700M+ contact database with AI-powered enrichment — search by company, title, industry, location
• Instant email and phone lookups built into the platform — no separate enrichment tool needed
• LinkedIn autopilot: collect contacts from LinkedIn searches, Sales Navigator, and post reactions automatically
• Social listening enrichment: discover leads from social conversations mentioning relevant topics, competitors, or buyer intent signals
• Contact verification included — verified leads marked in the database, reducing bounce risk
• Import enriched contacts directly into multi-channel sequences without CSV export/import
• Integrations: sync enriched contacts to HubSpot or Attio CRM for downstream use
• No public API for enrichment — all enrichment happens within the BrandJet platform
• Starter plan: 1,000 verified leads/mo; Pro plan: 10,000 verified leads/mo — monthly credit model, plan usage carefully

In Nooks (Waterfall Enrichment)

• Waterfall enrichment: Cascades across 9 data providers to find verified contact data: Apollo, Cognism, ContactOut, Datagma, Forager, LeadIQ, PDL (People Data Labs), Prospeo, ZoomInfo
• Automatic number verification: Validates phone numbers before they enter the dial queue, reducing bad-number waste and improving connect rates
• Catch-all detection: Identifies and flags catch-all email domains, prioritizes verified email addresses for outreach
• Enrichment is built into the dialing workflow: Prospects are enriched as they're added to call lists — no separate enrichment step needed
• No standalone enrichment API: Enrichment happens within the Nooks platform, not via a public API. You can't use Nooks as an enrichment provider for external tools
• Coverage focus: Optimized for finding direct mobile numbers (the primary channel for parallel dialing). Email enrichment is secondary
• Best for: Teams using Nooks for dialing who want enrichment bundled into the workflow. For standalone enrichment across tools, use Clay waterfall or dedicated enrichment providers

In Amplemarket

• Searcher database: 300M+ verified contacts with 70M+ weekly updates. Search by industry (1000+), department, job function, company size, funding stage, technologies, location
• Single enrichment: GET /people/find — find one person by name + company or LinkedIn URL. Costs 0.5-1 email credit + 1 phone credit per reveal
• Batch enrichment: POST /people/enrichment-requests — up to 10K contacts per request. More credit-efficient than individual lookups. Poll GET /people/enrichment-requests/{id} for results (check Retry-After header)
• Company enrichment: POST /companies/enrichment-requests — up to 10K companies per batch. Returns name, domain, LinkedIn URL, industry, headcount, funding, technologies, locations, revenue, B2B/B2C flags
• Email validation: Separate from enrichment — POST /email-validations validates existing emails (100K max, 15K/hour). Results: deliverable, risky, unknown, undeliverable
• Credit economics: Email reveals cost 0.5-1 credit each. Phone reveals cost 1 credit each. Credits reset monthly. Phone credits are the expensive resource — only reveal phone numbers for high-priority prospects
• Data accuracy: ~95% for US contacts (industry-competitive). International data accuracy is significantly lower — budget for 10-20% higher bounce rates on non-US data. Validate international contacts with the email validation endpoint before sequencing
• Cancel in-progress enrichment: PATCH /people/enrichment-requests/{id} — useful for stopping large batch jobs if you realize the filters were wrong
• Rate limits: /people/search is 300/min (stricter than the general 500/min limit). /people/find is 350/min. Plan batch operations accordingly
• Best for: Teams using Amplemarket as their primary outreach platform who want enrichment built into the same workflow. No need for separate enrichment tools — data access is native. For standalone enrichment feeding external tools, the API supports it but credit costs add up at volume
• Platform skill: /sales-amplemarket

In Sendr (Data Studio)

• Data Studio module: Verify and enrich contacts in Sendr's Sheets (internal spreadsheet-like data structure)
• Email verification: Validate emails before building personalized pages — avoids wasting credits on invalid contacts
• Personality analysis: Classifies contacts by personality type (e.g., "high green") to inform outreach tone. Unique to Sendr — most enrichment tools don't include behavioral profiling
• Lead Finder as enrichment source: 479M+ B2B contacts refreshed monthly. Use Lead Finder to fill gaps in existing lists (missing emails, phone numbers)
• API enrichment (Pro plan only): Add rows to Sheets via POST /api/v1/sheet/{sheetId}/row, then run enrichment through the UI or automation builder
• Credit economics: Enrichment operations consume credits from the same pool as page generation. At Growth plan (2,500/mo), budget enrichment carefully if also generating personalized pages
• No waterfall enrichment: Unlike Clay or Nooks, Sendr uses a single data source (its own 479M+ database). For comprehensive enrichment, combine Sendr Lead Finder with Clay or Apollo for waterfall coverage
• Bulk operations: Data Studio supports batch cleaning and enrichment on entire Sheets. No documented API endpoint for batch enrichment — UI-based only
• Data accuracy: US data is stronger than international. Validate international contacts with email verification before spending credits on personalized pages
• Best for: Teams already using Sendr for outreach who want basic enrichment without a separate tool. For heavy enrichment workflows, pair with Clay or Apollo
• Platform skill: /sales-sendr

In Cognism

• CRM Enrichment module: Automated enrichment of existing CRM records at scale — connects to Salesforce (Professional+) and HubSpot (2-way sync) to refresh stale records with verified emails, phone numbers, job titles, and company data
• Diamond Data phone verification (Elevate plan only): Cognism's team manually calls mobile numbers to confirm they reach the right person. Claimed 98% accuracy, 22% connect rate. Grow plan mobiles are not phone-verified and have significantly lower connect rates
• Email quality caveat: Some email addresses are pattern-generated (firstname.lastname@domain) rather than verified. Run email validation through ZeroBounce or SafetyMails before large outbound campaigns to avoid bounces
• API enrichment: Search API finds contacts by filters (20-100 per request, 1,000 req/min), Redeem API returns full data based on your Entitlement. Entitlements must be configured in admin before API returns full fields
• Fair-use cap: "Unlimited" plans have a fair-use cap of ~2,000 records/user/month. Plan batch enrichment around this — for higher volume, contact Cognism about DaaS packages
• Regional data quality: EMEA data is industry-leading (strongest in UK, DACH, France, Nordics). US data has notable gaps vs ZoomInfo, especially mid-market. APAC is weakest — validate before use
• Waterfall enrichment position: Strong as primary provider for EMEA teams. For global coverage, pair with ZoomInfo (US) or Apollo (budget-friendly global). Cognism as secondary/tertiary in a waterfall adds EMEA phone coverage that other providers miss
• Bombora intent enrichment (Elevate plan only): Enrich accounts with intent topic scores showing active research behavior. 8-15 configurable topics. Combines with hiring/funding signals for composite scoring
• Credit economics: Quote-based pricing — Grow ~$15-25K platform + $1.5-2.5K/user/yr, Elevate ~$2.5K+/user. Discounts of 28-52% are common — never accept first quote. Watch for auto-renewal with 10-15% annual price increases
• Best for: Teams prospecting into EMEA who need phone-verified mobile numbers for cold calling. Diamond Data connect rates are the key differentiator. For US-only teams, ZoomInfo is stronger. For budget-conscious teams, Apollo offers more features at lower cost
• Platform skill: /sales-cognism

In LeadIQ

• Chrome Extension enrichment: One-click contact capture from LinkedIn profiles and Sales Navigator. Reveals emails (1 credit) and phone numbers (10 credits) with direct push to Salesforce or HubSpot. Best for real-time enrichment during active prospecting sessions
• CRM Enrichment module: Salesforce native managed package with bi-directional sync, field mapping, and duplicate detection via email/name/company domain matching. HubSpot connects through Workato middleware — adds setup complexity but supports custom field mapping
• Phone number accuracy caveat: Phone data is LeadIQ's #1 complaint across 1,000+ G2 reviews. Mobile numbers may be personal cells, outdated, or wrong person. Cross-validate high-priority numbers through Cognism Diamond Data or ZoomInfo before cold calling
• Account enrichment: 3 credits per company — returns technology stack, funding info, revenue range, employee count. Use to screen company fit before spending 10+ credits on individual contact reveals
• Credit economics: Email = 1 credit, phone = 10, both = 11, account = 3. Pro plan starts at ~$200/mo for 200 credits (= ~18 full contacts). Credits don't roll over. Phone lookups are 10x more expensive than email — budget accordingly
• API enrichment: GraphQL API at api.leadiq.com/graphql. HTTP Basic auth. searchPeople, searchCompany, flatAdvancedSearch, groupedAdvancedSearch queries. 10 req/min (free) or 60 req/min (paid). submitPersonFeedback mutation for data corrections
• Champion Tracking: Monitors existing contacts for job changes — unique feature for enriching your warm pipeline. Alerts don't consume credits until you reveal updated contact info at the new company
• Waterfall enrichment position: Good as a secondary source for US email data. Weak on phones compared to Cognism (EMEA) or ZoomInfo (US). Best value is the champion tracking feature — no other enrichment tool offers systematic job change monitoring at this price point
• Best for: SDR teams doing high-volume LinkedIn prospecting who want one-click CRM push. Champion tracking is the key differentiator. For phone-heavy outbound, pair with a provider that has stronger phone verification
• Platform skill: /sales-leadiq
