SMS Event Processing Delays
Resolved - SMS events have been restored to real time processing as of 6:38 PM ET on May 19, 2026. Our Engineering team has monitored performance and see that systems have fully recovered. This incident has been resolved.
May 19, 20:30 EDT
Identified - We have identified the cause of the issue and SMS event processing is recovering. Delays in processing SMS events are currently around 3 hours and continue to decrease. SMS campaign sending continues to be unaffected and recipients are continuing to receive messages at the expected send times. Customers may continue to see downstream delay in SMS event-triggered flow sending, real-time segments built on SMS event data, and reporting until processing has fully caught up. Customers may also encounter errors when creating and registering RCS agents, and when viewing videos within the platform. We'll provide updates as soon as more information is available.
May 19, 18:21 EDT
Investigating - SMS event processing is delayed by approximately 2–3 hours. SMS sending is not impacted and recipients are receiving messages at the expected send times. This is impacting when SMS-related events appear in customer accounts, which may cause a delay in SMS event-triggered flows, real-time segments built on SMS event data, and reporting. Our team is actively investigating and we'll provide updates as soon as more information is available.
May 19, 16:36 EDT
Page loading errors
Resolved - The intermittent errors, slow page loads, and delays for email and SMS sends have been resolved. A small number of push notifications from impacted flows are being replayed and will deliver shortly. This incident has been resolved.
May 19, 13:38 EDT
Monitoring - A fix has been deployed and system performance is improving. Intermittent errors, slow page loads, and delays for email and SMS sends are recovering. We continue to monitor closely.
May 19, 13:17 EDT
Identified - We have identified the cause of the intermittent errors and slow page loads some customers are experiencing in the Klaviyo app. Some customers may also be experiencing delays of up to 20 minutes for email and SMS sends, as well as delays in flows that send push notifications. Our engineering team is deploying a fix.
May 19, 12:46 EDT
Investigating - Customers may be experiencing intermittent errors and slow page loads in the Klaviyo app. Our engineering team is actively investigating. We'll provide updates as soon as more information is available.
