Back In Stock has a one-click setup without coding, automatically enabling the 'EMAIL ME' button on your product page (Support Online Store 2.0). When you restock, we will send customer alerts. You can also design your email notification template for the app block, which is easy and powerful for attracting customers' attention and thus winning back lost sales. We are also start-up friendly with 24/7 live chat support waiting to solve all your concerns.
