What This Skill Does

Covers the Resend email API for sending single and batch transactional emails, receiving inbound mail via webhooks, and managing templates, domains, contacts, and broadcasts. Includes SDK setup for 8+ languages and documents gotchas like idempotency keys, webhook signature verification, and the Node.js SDK's non-throwing error pattern.

Resend's SDK has non-obvious patterns (errors returned instead of thrown, webhook payloads missing email bodies, idempotency key formats) that this skill documents upfront so you avoid duplicate sends and silent failures.

When to use it

  • Sending order confirmation or password reset emails through Resend's API
  • Setting up webhook endpoints to track delivery, bounces, and spam complaints
  • Building an inbound email processor that reads and acts on received messages
  • Batch sending onboarding emails to groups of new users
  • Managing email templates with dynamic variables for multi-environment deploys
