Agent Email Inbox

This is Resend's official skill for building email-triggered workflows with actual security patterns baked in. If you're building an AI agent inbox, support ticketing system, or anything that lets untrusted emails trigger code execution, start here. The skill enforces webhook-based receiving (no polling), includes sender allowlists and domain filtering, and covers the DNS setup for custom domains. It defaults to strict security levels because the alternative is letting random internet strangers send commands to your agent. The documentation includes SDK version requirements across eight languages and proper webhook verification patterns. Use this anytime email becomes an input channel, not just for "agent" use cases.
