The product information section, where the Back in stock alert block goes

The Back in stock alert block in Product information shows a small email form on sold-out variants only. It is already in the default product template; add it with Add block > Back in stock alert if you removed it.

What happens

  1. A shopper on a sold-out variant enters their email and selects Notify me. Signed-in customers find their email filled in.
  2. They see a thank-you message.
  3. Shopify sends you a contact form email tagged back-in-stock, with the product name, the variant and a link to it.
Switching to an available variant hides the form again.

Settings

Edit the block’s Heading and Text. The other words, such as Notify me, live in Edit default theme content.

Good to know

  • The theme doesn’t send the restock email for you. Reply to each request when the item is back, or install a back-in-stock app if you want automatic emails.
  • A variant that has Continue selling when out of stock turned on is still available, so it shows Pre-order instead of this form.
