Lunya review for Amp: Back in Stock & PreOrder+

It's easy to get the basics of what we need but some additional analytics, for example, would be great. Perhaps if the app was directly linked to Shopify as well. Currently, it doesn't look like the BIS app will show as purchased unless purchased through the BIS trigger email and, I couldn't find a way to manually send a notification to, say, one customer, if needed. Customer service has been great!
