Absolutely love the app. Free, does what it says, and let's you send transactional emails. 10/10.

Quickest support I have ever experienced made setup much more satisfying. Awesome app as well; provides more features than others for the same price!

It’s pretty good. Can make a professional design which is highly customisable. Really recommend to anyone who has started making a few sales and needs good upsells. Support also responds quickly, and fixes the issue quickly.

pretty good to increase sale value. really recommend. Also pretty cheap and support helped me quickly.

This app at first didnt fullfill any orders and I was really frustrated. I even payed for an order and it showed up as awaiting payment. I was frustrated for what felt like an hour. I found their customer support and they replied instantly and told me how to fix the issue in less than 5 minutes. These guys are amazing.
