SendWILL Popup Email Marketing

Just added the app, so far very responsive chat support to remove their "powered by" phrase, which I suppose is a welcoming intro to them and am writing this review at their request. I tried a few pop-up apps before this, and by far this has been the easiest to use and it seems to work flawlessly with Shopify. I use Shopify email so that integration was very important to me. So far so good!
