Mailx Skills
Register MailX deliverability skills so your agent can audit SPF, DKIM, DMARC, BIMI, blacklists, and mail server connectivity before you scale outbound email.
Overview
mailx-skills is a plugin marketplace for the Ship phase that adds MailX email-deliverability skills for SPF, DKIM, DMARC, BIMI, blacklist, and SMTP/IMAP diagnosis plus DNS fixes.
What is this marketplace?
- 1-plugin email-deliverability skill (v1.2.0, MIT) from MailX
- Checks SPF, DKIM, DMARC, BIMI, blacklist status, SMTP/IMAP connectivity
- Generates DNS records for email authentication fixes
- Keywords include MCP alongside deliverability diagnostics
- Homepage documentation at themailx.com/mcp/docs
- 1 plugin in marketplace (email-deliverability v1.2.0, MIT)
- Documented checks: SPF, DKIM, DMARC, BIMI, blacklists, SMTP/IMAP
What problem does it solve?
Launching email without verified authentication and blacklist health leads to spam folder placement and no clear agent-native checklist to fix DNS and server issues.
Who is it for?
Solo builders shipping product email or cold outreach who need agent-guided authentication and reputation checks tied to MailX workflows.
Skip if: Teams only managing MailerLite campaigns inside a ESP UI with no DNS or deliverability debugging needs.
What do I get? / Deliverables
After install, your agent can run MailX deliverability diagnostics, interpret auth record gaps, and output DNS record fixes before you send at scale.
- Enabled email-deliverability plugin (v1.2.0)
- Diagnostic reports and generated DNS authentication record recommendations

Journey fit
Ship security is the canonical shelf because authentication records and blacklist checks are launch gates that prevent reputation damage when you start sending. Security subphase covers DNS authentication, protocol checks, and remediation—not campaign copy or analytics dashboards.
How it compares
Deliverability and auth diagnostics skill pack (MCP-adjacent docs), not an ESP lifecycle marketplace.
