Shopify back in stock notifications: the notify-me flow

Checked against the live sources below on 27 October 2026.

A back-in-stock notification lets a shopper leave an email address on a sold-out product and get a message when it returns. An app adds the button and sends the email. Low Stock Alerts & Notify Me includes the notify-me button on its free plan and emails waiting shoppers when you restock.

How the notify-me flow works

  1. A shopper lands on a sold-out product and sees a notify-me button instead of a dead end.
  2. They leave an email address.
  3. You restock the item.
  4. The app emails everyone waiting on that product, and the sale you thought you had lost comes back.

The value is that the shopper has already told you they want the product, so the message is one they asked for. Only use the address for that restock notice. Keep the email short: the product, a photo and a button back to the page.

Where setups quietly fail

  • The button never appears. Before you install any back-in-stock app, check whether it needs a theme setting (an app embed) turned on before the button shows on your storefront. Then open a sold-out product on your phone and look.
  • Variants. A shopper who wants one size needs to be told about that size. Test a sold-out variant, not just a sold-out product.
  • The email never arrives. Sign up with your own address, restock, and see whether it lands in the inbox, not spam.
  • No one told you it was low. A notification recovers a lost sale; an early low-stock alert prevents the loss. See low stock alerts.
  • Stock updated late. The notice can only go out after the product shows as available, so update inventory as soon as the delivery is counted.

What to check on any listing

Before you compare apps, check three things on each listing: the channel (email only, or also text messages), how many notifications the free plan allows, and whether signup works on each variant. Compare prices after that.

Other questions worth asking: can you see how many shoppers are waiting on each sold-out product, so you know how much to reorder? Can you edit the email? Is there a way to test a signup without waiting for a real restock?

Where Low Stock Alerts & Notify Me fits

Its App Store listing describes a notify-me button on sold-out pages: shoppers leave their email, and the app lets them know the moment the item is back. The button is part of the Free plan, together with low-stock alerts for you. The listing describes email notifications; it does not describe text messages, so if you need those, this is not the right app.

Add a notify-me button to sold-out products on the free plan.
