Shopify created Abandoned checkouts case, but Klaviyo did not send emails

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:

  1. Why Klaviyo does not send multiple emails in this scenario?

  2. Which flow setting, event property, or built-in suppression rule is preventing the second email from sending?

  3. 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

@teachateau, this is either due to (1) smart sending, which is enabled by default on your flow messages, or (2) a profile filter on the flow that looks something like this which is checked before each action in the flow is executed.

 


You could theoretically turn off smart sending for the flow message OR adjust such a profile filter. I do think it’s worth having some kind of filter. Typically subscribers don’t like getting multiple duplicate abandon cart emails in the same day, even if they’re shopping across multiple devices. 

Klaviyo has a good guide on setting up an abandoned cart flow here - https://help.klaviyo.com/hc/en-us/articles/115002779411
