What brands are saying

"We started using KeepCart a few months ago when our previous solution stopped working. We were using another app and they no longer were able to offer support to Shopify stores, so we quickly scrambled to find a new solution. KeepCart was affordable and got the job done!"

"Easy to use, easy to install, and does what it says it is going to do. We have been using for a few months now, and the app has paid for itself multiple times over. Their team is extremely fast to reply and always has helped with any questions that we have had. They consistently ask for feedback for how the app could improve and are open to all suggestions. Definitely recommend!"

“Quick and easy app to install. They continue to roll out new and helpful features like shield links, duplicate customer detection, and coupon extension analytics, etc. Pricing is competitive and customer success is responsive. Would recommend!”
