Issue with Time Delays in Flows
Resolved - As of 11:26 PM US/Eastern on August 26, 2026, the repair to process affected flow messages from the window of impact has been completed, and flow sending has resumed as expected across all channels. We apologize for the disruption this caused. This incident has been resolved.
Aug 26, 23:42 EDT
Monitoring - As of 9:30PM US/Eastern, flows have resumed sending as expected across all affected messaging channels. We are processing the backlog of affected flow messages. A fix has been deployed and system performance is improving.

We continue to monitor closely and appreciate your patience throughout this incident.
Aug 26, 21:51 EDT
Identified - Our Engineering team has identified the cause of this issue and is working to implement a fix to resolve the remaining impact on sending for flows affected by the time delay issue. Once the fix is rolled out, we will review and repair any impacted flows.

We are working to resolve this as quickly as possible and will share another update shortly.
Aug 26, 21:15 EDT
Investigating - At 3:25 PM US/Eastern on August 26, 2026, we began experiencing an issue where some profiles are not progressing past time delay actions in flows as expected. This is affecting flow sending across all messaging channels, including email, text messaging, push, and WhatsApp. Message sending from campaigns, and flows that do not include time delay actions are not impacted.

We are actively working on a fix. We will continue to provide updates as more information becomes available.

Delays in real-time segmentation
Resolved - Profile property updates are now being reflected in real-time segments at normal speed. Any profile property changes made during the incident window have been reflected in segment membership as expected, and no action is required on your part. This incident has been resolved.
Aug 19, 14:38 EDT
Monitoring - A fix has been deployed and system performance is improving. Recent profile property updates are now being reflected in real-time segments more quickly, and the delay has improved to approximately 2.5 hours. Changes to profiles may still take slightly longer than usual to update segment membership as the system continues to catch up. Email and SMS sending and other core functions remain unaffected. We continue to monitor closely and appreciate your patience throughout this incident.
Aug 19, 14:13 EDT
Identified - We are currently experiencing delays of up to approximately 3 hours in how quickly recent profile property updates are reflected in real-time segments. This means changes to profiles may take longer than usual to update segment membership, which can affect segment-based targeting. Email and SMS sending and other core functions are operating normally. We are actively working to resolve this and will share another update as soon as we have more information.
