Klaviyo

Some customers are experiencing delays with campaigns sending, and some scheduled campaigns may appear stuck or show no recipients while they process. We have identified the issue affecting a subset of campaign sending. If a scheduled campaign has not started sending, you can cancel and reschedule it to send again. We are working to resolve this as quickly as possible and will share another update shortly.

Between 11:00 AM US/Eastern and 5:00 PM US/Eastern on October 28, 2026, some customers may have seen flows skip profiles with the skip reason "Incorrectly Triggered," shown in flow and profile activity. Flows are no longer skipping profiles for this reason, and we are reprocessing impacted profiles. No action is needed from customers, and we will confirm once reprocessing is complete. We continue to monitor closely.

Some customers and third-party apps connected to Klaviyo accounts are experiencing delays receiving event webhooks. Webhook actions in flows are not affected at this time. To support recovery, we temporarily paused processing of new webhooks at 5:11 PM US/Eastern on October 22, 2026, and earlier webhooks are still being delivered with delays. Webhook data is being retained, and we expect delayed and paused webhooks to be delivered once processing resumes. We are working to resolve this as quickly as possible and will share another update shortly.

We are investigating reports of delays affecting flow message sending. Some customers may see flow messages send later than expected. Immediate sends are not affected and are going out as expected. We will share another update as soon as we have more information.

All customers are experiencing delays of up to an hour in analytics events, so Sent and Delivered reporting and received profile events may temporarily appear missing. Campaign and flow sending, along with open and click events, are not affected. We have identified the cause of the delays. We are working to resolve this as quickly as possible and will share another update shortly.

We are investigating reports that some customers are unable to log in to Klaviyo or are seeing pages load slowly or not at all. Our team is actively working to restore normal access. We will share another update as soon as we have more information.
