## Timeline of updates

- **update** 2025-10-06 23:32 UTC: As of October 6, 22,19 UTC, we noted a feature degradation impacting email routing. A subset of customers may observe failures with outbound emails when Einstein Activity Capture (EAC) is enabled, but email integration is disabled in their EAC email configurations. We discovered a recent release as the potential trigger and are identifying the best solution to resolve this issue. Thank you for your patience as we work towards a solution to this issue. We will provide an update in 30 minutes or sooner if additional information is available.
- **investigating** 2025-10-07 00:08 UTC: We are continuing to investigate the cause of this issue and have engaged additional engineers.
- **update** 2025-10-07 00:11 UTC: Investigations have highlighted that the impact radius is broader than initially understood. We have updated the posting to reflect the additional instances experiencing impact, and customers in these instances will receive communications related to this incident going forward.
- **update** 2025-10-07 01:23 UTC: Our teams have identified the issue and are working on fix forward. We are currently validating the fix in a dedicated lower environment. Upon successful validation, we will proceed with deploying this fix forward through our standard release process. We are unable to provide a specific time for the completion of these actions; however, we will provide an update once deployment begins, or sooner if additional information becomes available. We are committed to resolving this issue as quickly as possible and apologize for the inconvenience this has caused to your business.
- **update** 2025-10-07 03:15 UTC: We have validated the fix in a lower environment and are now preparing for deployment.

We remain committed to resolving this issue quickly and ensuring continued stability for our customers.
- **update** 2025-10-07 08:06 UTC: Upon further investigation, we have determined that both the impact and start time are different from what was initially understood. The Trust post has been updated to accurately reflect the correct impact details and revised start time.  We apologize for any confusion this may have caused and appreciate your understanding.
- **update** 2025-10-08 00:12 UTC: The deployment of the fix is underway, and is being undertaken in a staggered approach, out of business hours, per region. We appreciate your patience with this issue and apologize for any inconvenience this issue may have caused to customers.
- **update** 2025-10-09 03:18 UTC: We confirm that the deployment has gone through across all environments, as of 23:52 UTC on October 8, 2025. This update includes the necessary fixes to address the outbound email disruptions caused by the Einstein Activity Capture issue and ensures continued stability and performance. We apologise for how this incident may have affected you and your business. We’ll perform a full investigation of the incident, confirming the technical trigger and the underlying cause.
