Email skills for Claude Code and Codex
Email skills cover the whole channel: lifecycle and drip sequences, cold outbound, personal drafting, inbox triage, and the sending infrastructure underneath (Resend, Mailtrap, Amazon SES, Cloudflare). They help an agent write the message, wire the template, and keep deliverability rules such as SPF, DKIM and DMARC in view.

How to choose email skills
Decide which layer you need. Copy skills (emails, cold-email, email-drafter) produce sequences and drafts; developer skills (react-email, resend, sending-emails) build templates and send through an API; Gmail and Google Workspace recipes act on a real inbox.
Check credentials up front. Resend, Mailtrap, SES and Smartlead skills need that provider's API key, and the Gmail and gws recipes need an authorized Google account. Drafting and sequence-planning skills run on the brief you give them.
For outbound, pick a skill that treats deliverability and consent as part of the job: bounded follow-up counts, unsubscribe handling, and current Gmail and Yahoo sender rules. Review every send step yourself before a campaign goes live.
