About Resend

Resend expands from email API to full platform with SSO, analytics, and AI-native dev tooling

Resend has graduated from a developer email API to a platform with a visual broadcast editor, team auth (SSO), a metrics API, and deep integrations into AI coding environments. The free tier now supports three verified domains, which lowers the barrier for multi-project developers. Release cadence is high — six substantive features in two weeks.
