An online specialty retailer

$647K in abandoned cart revenue recovered in 180 days.

A specialty retailer with a large catalog and a long consideration cycle already had cart emails running through their ESP. Adding CartStack started recovery from every exit, not just checkout — and turned a fixed monthly cost into a 118X return.

The challenge

Most of the retailer's abandonment happened before checkout. Shoppers compared options across several sessions, added to cart, then left from the cart page or a product page — long before an email was captured. The existing ESP flow only fired for shoppers who reached checkout and entered an address, which meant the majority of high-intent traffic never heard from the brand again.

What changed

1

Recovery from every exit

Real-time email capture meant a contact existed the moment a shopper typed, not the moment they submitted. Cart, browse and checkout abandonment each got their own sequence.

2

Messages built from the cart

Every email carried the exact items, images and prices left behind, sent from the retailer's own domain in their voice — with the series stopping the moment a shopper came back.

3

Earlier capture on-site

Exit-intent and send-my-cart prompts asked for the email earlier in the visit, growing the pool of shoppers the recovery sequence could follow up with.
