## Updates from Resend
### 2026-07-30 09:58 UTC: identified
Performance degradation when sending test emails from the \[resend.dev\](http://resend.dev) domain, which is causing the API to return a validation error stating that the domain is not verified.

### 2026-07-30 16:23 UTC: resolved
We have resolved the underlying issue, and sending test emails from \[resend.dev\](http://resend.dev) has resumed.
