Timeline of updates

1. update2026-05-20 20:04 UTC

   At approximately 16:00 UTC on May 20, 2026, we became aware of a feature degradation impacting a subset of Marketing Cloud Engagement customers. A recent deployment that manages unsubscribe link processing has introduced an issue where some unsubscribe requests may not be successfully processed. This issue specifically impacts customers on Stacks 1, 5, 6, 7, 10, and 51 who utilize custom CloudPages for their unsubscribe branding or behavior. We estimate that roughly 25% of unsubscribe links may not properly process during an unsubscribe attempt. We have identified the trigger and are currently preparing remediation steps to restore normal functionality. We will provide an update in 30 minutes, or sooner if additional information becomes available.

2. update2026-05-20 20:26 UTC

   We completed the deployment of a fix to all six impacted stacks and we’ve now entered a monitoring phase to ensure the settings have fully propagated. We will begin the validation of the fix at approximately 20:30 UTC. We will provide an update in 60 minutes, or sooner if additional information becomes available.

3. update2026-05-20 21:21 UTC

   During the subsequent validation phase, we identified that the fix required a configuration adjustment to fully restore functionality. We have developed a revised remediation plan and are currently in the process of merging and deploying this update to the affected environments. We expect to begin the next round of validation shortly. We will provide an update in 60 minutes, or sooner if additional information becomes available.

   Upon further investigation, we've determined that the start time of impact is different than initially understood. We've revised the start time of the Trust post to more accurately reflect the time customers may have begun to experience impact. We apologize for any confusion caused by this.

5. update2026-05-20 21:58 UTC

   Following the deployment of a remediation plan and subsequent validation by our teams, we confirmed that functionality for custom CloudPage unsubscribe requests has been fully restored as of 21:51 UTC. We apologize for the disruption this caused you and your business. We will perform a full investigation to identify the technical trigger and preventive actions to avoid a recurrence.
