- investigating Jun 22, 2026, 11:43 PM UTC
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.

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.

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.
