Update - The data processing delay has been resolved, and processing has returned to normal. Recurring campaigns have been resumed, and continuous campaigns are now running as usual.
Our team is actively monitoring the system to ensure continued stable performance. We will provide a final update once we have confirmed full recovery.
We apologize for any inconvenience this may have caused.

Jun 24, 2026 - 10:25 UTC
Update - We are continuing to monitor for any further issues.
Jun 24, 2026 - 09:20 UTC
Monitoring - We have implemented a fix, and data processing has resumed. The accumulated processing delay is now clearing, though it may take some time to fully catch up. Customers may continue to see some lag until the backlog has been processed.
Recurring campaigns in the US region remain temporarily paused. We will resume normal campaign scheduling once the backlog has fully cleared, to ensure no duplicate or double sends occur.
Our team is actively monitoring the recovery, and we will confirm once the system has fully returned to normal. Thank you for your continued patience.

Identified - Our team is actively working on a fix to resolve delayed data processing. Customers may continue to experience data processing lag while remediation is underway.
As a precautionary measure, we are temporarily pausing recurring campaigns in the US region to prevent duplicate or double sends while processing catches up. We will resume normal campaign scheduling once processing has fully recovered.
We will provide a further update as soon as we have more information. I appreciate your patience.

Jun 23, 2026 - 18:27 UTC
Investigating - We are currently experiencing data processing delays in the North America region. As a result, continuous campaigns will not run until the processing lag has cleared.
Our team is actively investigating and working to restore normal processing times. We will provide an update as soon as we have more information.
We apologize for any inconvenience and appreciate your patience.

Resolved - This incident has been resolved.
Jun 20, 17:41 UTC
Update - We are continuing to monitor for any further issues.
Jun 19, 22:29 UTC
Monitoring - We have deployed a fix to unblock affected customers and are actively monitoring the system to confirm stability. We are also working with our email vendor (SendGrid) to put a more complete solution in place on their side.
Please note: during the period when emails were partially dropped, we do not have a record of which individual recipients successfully received messages. As a result, if you choose to re-run an affected campaign (e.g., by sending it to a new campaign), some recipients may receive duplicate emails.
We will provide a further update as monitoring continues.

Jun 19, 21:50 UTC
Identified - We have likely identified the root cause as a recent SendGrid change that introduced an incompatibility in header processing. We are sharing our findings with SendGrid and implementing a workaround to restore compatibility.
Jun 19, 19:51 UTC
Update - We are still looking into this issue and will provide updates as they become available.
Jun 19, 19:02 UTC
Update - We are continuing to investigate this issue. We also have a support thread open with Sendgrid.
Jun 19, 12:13 UTC
Investigating - We are investigating an issue causing some email campaign messages to be dropped in the North America region. Some emails are still being delivered. Accounts using email campaigns in the region may be affected.
We will update as we learn more.
