Here you want your customers to be notified when products they want come back in your stock.
his flow starts when you create a pop-up or an embedded form on your website where customers enter their email address to be informed when a particular product becomes available again.
Subscribers exit this flow when they place an order.
With this flow, you make up orders that wouldn’t be placed otherwise. That way you increase your sales. This flow also helps you build brand loyalty and anticipation around your products. But make sure customers don’t wait too long for your products.
