Resend Email Best Practices
Resend's official email skill: deliverability, compliance, and webhooks
About
Resend's official agent skill is a single SKILL.md router backed by ten reference docs covering the unglamorous parts of email: SPF, DKIM, and DMARC setup, transactional versus marketing email patterns, CAN-SPAM/GDPR/CASL compliance, idempotent sending with retries, webhook processing, and suppression-list hygiene. It is lean and focused rather than a framework, which makes it easy to adopt. The honest boundary: it teaches best practices, not Resend SDK usage, and the references assume you handle your own sending infrastructure.
