What it does

Comprehensive guidance for engineers building email features. Covers DNS authentication (SPF/DKIM/DMARC), deliverability troubleshooting, transactional vs marketing email design, capture/consent flows, webhook handling, idempotent sending and retry logic, bounce and suppression handling, and legal compliance (CAN-SPAM, GDPR, CASL). Includes reference documents for common tasks so engineers can follow checklists and examples.

When to use it

Use this skill when implementing or debugging email sending in an app: setting up SPF/DKIM/DMARC; reducing spam and bounce rates; designing password reset, OTP, or transactional flows; building marketing campaigns safely; or wiring webhooks and delivery-event processors. Also useful for planning list hygiene jobs and suppression handling.

What's included

Scripts: none (has_references=true) — rich references/ documentation folder with step-by-step guides (deliverability, transactional catalog, webhooks, compliance).
References: Deliverability, Transactional Emails, Email Capture, Marketing Emails, Compliance, Sending Reliability, Webhooks & Events, List Management.
Instructions: architecture overview, quick-reference table mapping needs to reference docs, and practical start/repair guidance for new apps or spam issues.

Compatible agents

Designed for general-purpose assistant agents and coding assistants that provide engineering guidance (Claude, Codex, OpenClaw sessions, GPT-family).

Audit Summary

A reference-oriented skill from Resend providing email best practices guidance (deliverability, compliance, webhooks, retries, list management). No scripts included — pure Markdown with an architecture diagram and links to references/. Well-structured SKILL.md with clear trigger descriptions and contextual entry points, but limited actionable automation since it's guidance rather than tooling. Mild commercial self-promotion via links to Resend docs but no security concerns.

Watch Out

Pure reference skill — no scripts to execute or automate tasks
Links to Resend commercial docs as primary references

Notes

Clean skill with no security issues. Well-organized using references/ pattern. Value is primarily as a knowledge base rather than an automation tool. Would benefit from actionable scripts for common tasks like SPF/DKIM validation or email header checks.
