Update timeline

  1. resolved Aug 13, 2025, 01:38 PM UTC

    Between 11:09 and 12:11 UTC, requests using newly created API tokens or newly added domains could intermittently fail via the Email API and SMTP. Some SMTP health checks on ports 587 and 2525 also failed briefly. Existing senders and ongoing bulk/campaign sends were largely unaffected. A subset of demo and forwarded emails experienced delays. **What happened** A database change shipped without the required indexes, causing slow queries and timeouts in token validation and SMTP health checks. New tokens and domains were most affected. **What we fixed** We added the missing indexes and verified recovery. All health checks are passing and delivery is operating normally.
