Back In Stock Notifications makes it possible for logged-in customers and guests to get notified via e-mail when out-of-stock products become available. The plugin appends a sign-up form right after the “Out of stock” availability status of sold-out Simple products and Variations.
Important: If you have configured WooCommerce to hide out-of-stock products and variations in your catalog, customers will not be able to sign up for back-in-stock alerts. To check your settings:
- Navigate to WooCommerce > Settings > Products > Inventory.
- Make sure that Out of stock visibility > Hide out of stock items from the catalog is disabled.
Notification sign-ups for all products are listed under WooCommerce > Stock Notifications > Notifications. Notifications can be:
- filtered by customer e-mail, product, or variation; and
- exported in a CSV file — useful if you need to import contact details in your favorite e-mail marketing platform/tool.
When a product is restocked, the plugin creates a queue with all pending notification e-mails and processes them in batches using Action Scheduler – a robust, battle-tested task processing system used by WooCommerce core. Thanks to Action Scheduler, the plugin can send an unlimited number of notifications without issues.
Note: Back In Stock Notifications cannot guarantee or measure e-mail deliverability. Most e-mail providers limit the number of e-mails that you can send through them per day. For example, Gmail will not deliver more than 500 e-mails/day. For details, please read this E-Mail FAQ. If your store is sending a large volume of e-mails:
Back In Stock Notifications can be configured to send notifications only when restocking above a minimum quantity threshold. For a detailed list of all settings provided by the plugin, check out the Getting Started > Settings section of the Store Owner’s Guide.
Important: Back In Stock Notifications requires WooCommerce 3.5+.
