Our Back in Stock app helps you retain customers and recover lost sales by automatically notifying them when out-of-stock items are restocked. Customers can sign up for alerts directly on product pages, and the app will manage the waitlist. You can export customer emails from our app and customize the pop-up form to match your brand colors. The app supports home, product, and collections pages. Easy to install and customize, this app ensures you never miss a sale due to stock issues.
