Resend outage: Errors during the domain creation process

1. resolvedAug 13, 2026, 17:43 UTC

   Between approximately 17:30 and 17:43 UTC, requests to add a new domain failed in the dashboard and through the public API (POST /domains). Verification of domains added during this window was also affected. The issue was identified and fixed, and domain creation has returned to normal. No domains were partially created: affected requests failed immediately, so retrying the domain creation will succeed. Email sending for existing domains was not affected.
