Incident Report

We’re currently investigating an issue with the Mailchimp Audience integration and, to protect stability, syncing is currently turned off. The team is implementing changes to reduce request volume and re-enable syncing as soon as validation completes. Audience updates from Affinity lists may not appear in Mailchimp while paused, but there is no data loss. We’ll post an update once the fix is validated and rollout begins.

We have made a change to reduce request volumes which will mitigate this issue. Given the complexity of the change, we will me monitoring it through the weekend and will perform rigorous validation before re-enabling the Mailchimp Audience integration, which we expect to happen early next week.

We apologize for the inconvenience and will post another update as soon as we begin the production rollout or if the timeline changes.
