Start on abandoned carts from Klaviyo
Reach shoppers who add to cart and leave before checkout: what counts as an abandoned cart, the wait, consent, and how ACR keeps it to one run per shopper.
Last reviewed November 7, 2026
What it does
A checkout is not the only sign someone meant to buy. With Start on abandoned carts (from Klaviyo) switched on, a Recover abandoned checkouts campaign also starts for a shopper Klaviyo knows who adds to cart and leaves without starting a checkout.
Klaviyo only tracks shoppers it can identify: someone who signed up through a form or pop-up, or clicked one of your emails. Anonymous visitors never become carts.
The switch is on the campaign's Start conditions step, under Abandoned carts. It is off for new campaigns and applies at once, like the trigger switches.
What it needs
- Klaviyo connected with an Added to cart metric picked, and ACR reading Klaviyo events; see Klaviyo.
- The campaign published, with its checkout trigger on. Carts start a campaign only while that trigger is on, so pausing the campaign or switching its trigger off stops carts too.
- A shopper with a phone number and text or call consent the campaign accepts. A new shopper becomes an ACR lead from a cart only when their Klaviyo profile has SMS consent; everyone else is never stored.
The card lists whatever is still missing under Carts are not starting this campaign yet.
Shoppers with email consent only do not start from a cart: Klaviyo's own abandoned-cart emails reach them already.
The wait
Each add to cart moves the shopper's cart along. When Minutes after the last add to cart pass (60 by default, 15 minutes to 7 days) with no checkout and no order, the cart counts as abandoned and is offered to the campaigns that start on carts, in their order on the Start conditions step.
Before the offer, ACR reads the shopper's consent from Klaviyo again. Start conditions, quiet hours, opt-outs, the do-not-contact list and the campaign's limits apply as they do to checkouts.
The agent gets the cart's items and total, and a link that rebuilds the same cart on any device when Klaviyo sends the product variants.
One run per shopper
- A checkout started after the cart takes over: the cart is dropped and the checkout gets its own wait. Klaviyo's Checkout started event drops the cart as well, even before the checkout reaches ACR.
- An order after the cart drops it, and an order during a cart run stops the run.
- A shopper already in a run is not started again.
- After a cart run, a checkout from the same shopper starts no run within the trigger's cooldown (30 days by default), and the other way round.
