Back-in-Stock Notifications

Back-in-stock notifications let customers subscribe to alerts for out-of-stock products. When inventory is replenished, subscribers automatically receive an email notification.

Note: Back-in-stock notifications require the Premium plan.

  1. When a product is out of stock and in an active pre-order offer, a “Notify Me” button appears on the product page
  2. Customers click the button and enter their email address
  3. When the product is restocked (inventory webhook fires), subscribers receive an email
  4. Subscribers can click through to purchase the product

Back-in-stock is automatically available for products in active offers with the Allow when out of stock inventory mode.

No additional configuration is needed. The “Notify Me” button appears automatically when:

  • The offer is active
  • The inventory mode is “Allow when out of stock”
  • The product variant is out of stock

Back-in-stock emails are sent through your configured email provider. Make sure you have:

  1. An email provider set up in Settings > Email (SMTP)
  2. Or the default email service configured

See Set Up Custom Email (SMTP) for email configuration details.

Subscribers are tracked per product variant:
