Hello,
We’ve set up an Abandoned Cart Reminder (Email) auto-flow in Klaviyo, using the trigger “When someone checkout started” to send reminder emails to customers who have abandoned their carts.
During our testing, we noticed an unexpected behavior:
When the same customer starts multiple checkout sessions using different browsers or devices (e.g., PC and mobile), Shopify creates multiple abandoned checkout cases.
However, Klaviyo only sends one abandoned cart email instead of one for each abandoned checkout session.
Could you help us understand:
-
Why Klaviyo does not send multiple emails in this scenario?
-
Which flow setting, event property, or built-in suppression rule is preventing the second email from sending?
-
Is this behavior expected, or should we adjust any filters, triggers, or flow configurations to ensure correct handling?
Any clarification or recommendations would be greatly appreciated.
Thank you!
Best regards
