Scheduled Maintenance

Infrastructure Maintenance Sep 23, 2026 04:00-05:00 UTC

We’ll be performing scheduled infrastructure maintenance on Wednesday, September 23, starting at 4:00 AM UTC. The estimated impact duration is 30 minutes.

During this window, you won't be able to log in or send new messages via SMTP or API. Don't worry, any emails already submitted will be queued and sent after the maintenance is completed.

As we come back online, you may experience brief sluggishness or intermittent errors, but this should resolve within a few minutes.

This maintenance is essential to keep the platform running smoothly.
