Hello everyone,
I'm reaching out to the community to understand a recent issue we've encountered with our "Added to Cart" email flows in Klaviyo using Shopify. In the past, our flows were set up similarly to "Started Checkout" flows where each email would iterate over every item added to the cart, creating a detailed table of all products the customer showed interest in.
However, we've hit a snag. Currently, when the "Added to Cart" event triggers an email, it only pulls one item, despite multiple items being added to the cart. This is in contrast to the "Started Checkout" trigger, where the iteration works flawlessly, listing all items in the checkout table.
We've contacted Klaviyo support, and they're now indicating that the "Added to Cart" trigger will only ever show one item. This is puzzling because we have a history of "Added to Cart" flows that did exactly what we're trying to achieve now. How could we have multiple flows set up in the past that worked this way if it was never supported?
Has anyone else experienced this issue or found a workaround? It seems like a significant design limitation, especially since "Added to Cart" is an important trigger that can indicate a customer's buying intent just as much as "Started Checkout."
Any insights, shared experiences, or solutions would be greatly appreciated!
Thank you!
Setting Up Email Flows for "Added to Cart" That Load All Items

As far back as I can recall, Added to Cart metric has been a single product trigger.
Thinking of it like someone has just hit the add to cart button on site and it is capturing that single moment as where Checkout Started is that full cart being abandoned. Honestly I find it most useful for your returning customer-base than anything. To add an extra wrinkle here too, I’ve run through A/B tests with different client types and find that an email that showcases the full cart items vs just one item doesn’t have a high affect on your CTR as much as it may seem. So normally I even just build abandoned checkout flows with the first item left in their cart and get just as good CTR if not better.
