Resend — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the resend-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:

1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows:

   npx -y @mvanhorn/printing-press-library install resend --cli-only

2. Verify: resend-pp-cli --version 3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill.

If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.4 or newer):

go install github.com/mvanhorn/printing-press-library/library/productivity/resend/cmd/resend-pp-cli@latest

If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds.

When to Use This CLI

Use this CLI when an agent needs to answer cross-resource questions about a Resend account that the dashboard or SDK cannot answer in one call — what did we send to a specific recipient, which audiences is a contact in, how does broadcast performance trend over time, what's the 7-day bounce rate. Stick with npx resend send for one-shot transactional sends or with React Email for templates; this CLI is the agent-facing companion, not a replacement.

Unique Capabilities

These capabilities aren't available in any other tool for this API.

Cross-resource queries over local state

• `emails to` — Every email sent to a single recipient address, with delivery status and timestamps, ordered newest-first.

_Reach for this when an agent needs to reconstruct what a single user has received — support tickets, GDPR exports, dispute investigations._

  resend-pp-cli emails to <your-email> --json --select id,subject,status,sent_at

• `emails timeline` — Collapsed event chain for a single email: sent → delivered → opened → clicked → bounced, in one ordered table.

_Use when debugging 'why didn't this arrive?' — one command shows whether it was sent, delivered, opened, or bounced and when._

  resend-pp-cli emails timeline 4ef9a417-d4ff-4ec5-9af2-c80a4d5d2c1f --json

• `audiences inventory` — Per-audience rollup: contact count, unsubscribed count, last-broadcast timestamp, recent open-rate.

_Use before planning a campaign — quickly see which audiences are healthy and recently engaged._

  resend-pp-cli audiences inventory --json

• `contacts where` — Find every audience, segment, and topic a contact (by email or name) belongs to in one query.

_Use when triaging unsubscribe requests, GDPR deletions, or 'why is bob getting this email?'._

  resend-pp-cli contacts where <contact-email> --json --select audience_name,subscribed

Aggregate analytics from local store

• `broadcasts performance` — Open / click / bounce rate across all broadcasts, sortable; not limited to a single broadcast or 30-day window.

_Use to compare campaign performance across the lifetime of the account._

  resend-pp-cli broadcasts performance --json --select broadcasts,count,status

• `domains health` — Verification + DKIM/SPF/DMARC status across every domain in one table, flags missing or unverified records.

_Use on call-out / deliverability incidents to confirm all sending domains are fully verified._

  resend-pp-cli domains health --json

• `deliverability summary` — Bounce rate, complaint rate, and suppression count over a rolling window (default 7d) computed from local event data.

_Use weekly to monitor IP/domain reputation trends before they cause deliverability incidents._

  resend-pp-cli deliverability summary --window 7d --json

Operational hygiene

• `api-keys rotation` — API keys sorted by age + last-used timestamp (joined from logs); flags stale keys older than N days.

_Use during quarterly security reviews — find unused keys that should be rotated or revoked._

  resend-pp-cli api-keys rotation --older-than 90d --json

Finding the right command

When you know what you want to do but not which command does it, ask the CLI directly:

resend-pp-cli which "<capability in your own words>"

which resolves a natural-language capability query to the best matching command from this CLI's curated feature index. Exit code 0 means at least one match; exit code 2 means no confident match — fall back to --help or use a narrower query.

Recipes

Reconstruct what a user has received

resend-pp-cli emails to user@example.com --json --select id,subject,status,sent_at,opened_at --limit 50

Use this for support tickets and GDPR exports — every email sent to one recipient, with delivery state.

Pre-campaign audience check

resend-pp-cli audiences inventory --json --select name,contact_count,unsubscribed_count,last_broadcast_at

Run before scheduling a broadcast — surfaces audiences with high unsubscribe rates or stale engagement.

Weekly deliverability review

resend-pp-cli deliverability summary --window 7d --agent --select bounce_rate,complaint_rate,suppression_count

Trend snapshot for IP/domain reputation; pipe through jq to alert on threshold breaches.

Audit stale API keys

resend-pp-cli api-keys rotation --older-than 90d --json --select name,created_at,last_used_at

Find unused keys during quarterly security reviews.

Search every sent email for a phrase

resend-pp-cli search 'password reset' --json --select id,subject,to,sent_at

FTS5-backed; needs sync --full first.

Auth Setup

Run resend-pp-cli auth setup for the URL and steps to obtain a token (add --launch to open the URL). Then store it:

resend-pp-cli auth set-token YOUR_TOKEN_HERE

Or set RESEND_API_KEY as an environment variable.

Run resend-pp-cli doctor to verify setup.

Agent Mode

Add --agent to any command. Expands to: --json --compact --no-input --no-color --yes.

• Pipeable — JSON on stdout, errors on stderr
• Filterable — --select keeps a subset of fields. Dotted paths descend into nested structures; arrays traverse element-wise. Critical for keeping context small on verbose APIs:

  resend-pp-cli api-keys list --agent --select id,name,status

• Previewable — --dry-run shows the request without sending
• Offline-friendly — sync/search commands can use the local SQLite store when available
• Non-interactive — never prompts, every input is a flag
• Explicit retries — use --idempotent only when an already-existing create should count as success, and --ignore-missing only when a missing delete target should count as success

Response envelope

Commands that read from the local store or the API wrap output in a provenance envelope:

{
  "meta": {"source": "live" | "local", "synced_at": "...", "reason": "..."},
  "results": <data>
}

Parse .results for data and .meta.source to know whether it's live or local. A human-readable N results (live) summary is printed to stderr only when stdout is a terminal — piped/agent consumers get pure JSON on stdout.

Agent Feedback

When you (or the agent) notice something off about this CLI, record it:

resend-pp-cli feedback "the --since flag is inclusive but docs say exclusive"
resend-pp-cli feedback --stdin < notes.txt
resend-pp-cli feedback list --json --limit 10

Entries are stored locally at ~/.resend-pp-cli/feedback.jsonl. They are never POSTed unless RESEND_FEEDBACK_ENDPOINT is set AND either --send is passed or RESEND_FEEDBACK_AUTO_SEND=true. Default behavior is local-only.

Write what surprised you, not a bug report. Short, specific, one line: that is the part that compounds.

Output Delivery

Every command accepts --deliver <sink>. The output goes to the named sink in addition to (or instead of) stdout, so agents can route command results without hand-piping. Three sinks are supported:

Unknown schemes are refused with a structured error naming the supported set. Webhook failures return non-zero and log the URL + HTTP status on stderr.

Named Profiles

A profile is a saved set of flag values, reused across invocations. Use it when a scheduled agent calls the same command every run with the same configuration - HeyGen's "Beacon" pattern.

resend-pp-cli profile save briefing --json
resend-pp-cli --profile briefing api-keys list
resend-pp-cli profile list --json
resend-pp-cli profile show briefing
resend-pp-cli profile delete briefing --yes

Explicit flags always win over profile values; profile values win over defaults. agent-context lists all available profiles under available_profiles so introspecting agents discover them at runtime.

Exit Codes

Argument Parsing

Parse $ARGUMENTS:

1. Empty, `help`, or `--help` → show resend-pp-cli --help output 2. Starts with `install` → ends with mcp → MCP installation; otherwise → see Prerequisites above 3. Anything else → Direct Use (execute as CLI command with --agent)

MCP Server Installation

Install the MCP binary from this CLI's published public-library entry or pre-built release, then register it:

claude mcp add resend-pp-mcp -- resend-pp-mcp

Verify: claude mcp list

Direct Use

1. Check if installed: which resend-pp-cli If not found, offer to install (see Prerequisites at the top of this skill). 2. Match the user query to the best command from the Unique Capabilities and Command Reference above. 3. Execute with the --agent flag:

   resend-pp-cli <command> [subcommand] [args] --agent

4. If ambiguous, drill into subcommand help: resend-pp-cli <command> --help.
