Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureNonito adds a Notify Me form to your sold-out products. Shoppers leave their email, and Nonito emails them the moment you restock - no list to manage and nothing to send by hand. In your admin you can see who is waiting and which items are most in demand, so you know what to reorder first.
Nudgeback adds a Notify me form to your product page. It appears only when the option a shopper picked is sold out, never on items you keep selling at zero stock. When stock returns, each waiting shopper gets one email with a link straight to that option. Stock is counted only at active locations that ship online orders, so stock that lands at a shop counter emails nobody. Moving from another app?
