The browse abandonment flow captures tracked Klaviyo profiles that have viewed a product but not started a checkout or placed an order.
The Added to Cart-triggered abandoned cart flow is intended to notify tracked Klaviyo profiles that added an item to their cart, but did not trigger a checkout or place their order.
The Started Checkout-triggered abandoned cart flow captures tracked and non-tracked customers who have entered their email at the first step of checkout.
Each flow targets a different step in the purchasing process and all flows should be set to skip profiles that have either started a checkout or placed an order since starting the flow. Browse abandonment is step 1 of the process, Added to Cart-triggered abandoned cart is step 2, and Started Checkout-triggered abandoned cart is step 3.
