- investigating Aug 26, 2025, 03:39 PM UTC
We are investigating an issue causing email delivery performance.
- identified Aug 26, 2025, 04:38 PM UTC
The issue has been isolated, and resources are being reallocated to empty the email delivery queue as quickly as possible.
- monitoring Aug 26, 2025, 08:24 PM UTC
The team has resolved email delivery performance, and inbound messages have been arriving as expected since about 1:00 PM ET. However, the issue is still monitored as API-related actions (sender training, message moves, etc.) and logs catch up. Please be aware that emails may sit in a folder a little longer than expected, and Spotlight logs may display an incorrect email location while the database catches up on activity. We expect the issue to be resolved entirely this evening.
- resolved Aug 27, 2025, 01:33 PM UTC
Email delivery and API activity are operating as expected.
