Updates from Klaviyo 3
- identified
We are currently experiencing delays of up to approximately 3 hours in how quickly recent profile property updates are reflected in real-time segments. This means changes to profiles may take longer than usual to update segment membership, which can affect segment-based targeting. Email and SMS sending and other core functions are operating normally. We are actively working to resolve this and will share another update as soon as we have more information.
provider
- monitoring
A fix has been deployed and system performance is improving. Recent profile property updates are now being reflected in real-time segments more quickly, and the delay has improved to approximately 2.5 hours. Changes to profiles may still take slightly longer than usual to update segment membership as the system continues to catch up. Email and SMS sending and other core functions remain unaffected. We continue to monitor closely and appreciate your patience throughout this incident.
