Testing now and it seems to me great. Works with Shopify which was our main intention to buy. Once you connect your Shopify store you can pull up all details, contacts etc. The good think is that Notify Visitors gives you a ton of features such as SMS, push notifications, emails, SMS broadcast etc. which saves us money, time and mainly no need to inject a ton of Shopify plugins and JS scripts which affects your Google rating. As of now it works great. I'll update my review later on once I'll go through all features.
