What Klaviyo said
On their page: Sync Tasks Failing
Klaviyo's status page: “Beginning around 8:09 AM US/Eastern on July 23, 2026, profile imports started through the API, CSV upload, or SFTP may fail to complete, and the imported profiles may not be created. New integrations connected during this period may also be delayed in starting their initial sync. We have identified the cause and are deploying a fix. We are working to resolve this as quickly as possible and will share another update shortly.”Identified
Klaviyo's status page: “Profile imports have recovered, and imports through the API, CSV upload, or SFTP are processing normally again. Integrations connected during the impact window are also resuming their initial syncs. Our team is working to reprocess API imports that failed during the incident.

Imports that failed during the incident were not reprocessed automatically. If an import you started between 8:00 AM and 11:00 AM US/Eastern on July 23, 2026 did not complete, please re-run it to ensure those profiles are imported. This incident has been resolved.”Resolved
