Resend - Anything

Resend Documentation

Resend provides reliable email delivery and tracking for your application’s email needs.

To send emails from a registered domain, you must verify your domain in Resend. Please follow the official Resend guide here.

Free plan limitation: On Resend’s free plan, emails can only be delivered to the email address you signed up to Resend with — regardless of use case. This includes contact form submissions, welcome emails, notifications, and everything else. To send to any other address, you’ll need to upgrade to a paid Resend plan.
