Requirements ↑ Back to top
The extension requires:
- WooCommerce 3.4+.
- A WordPress hosting environment that supports background processing through Action Scheduler, the task queuing system built into WooCommerce.
Note: Action Scheduler may fail to process background tasks if WP Cron is disabled on your system, or if your server is unable to “talk to itself” (perform loopback requests). When this happens, WooCommerce updates may fail to install, and other important tasks (such as e-mail deliveries) will not be processed.
Getting Started ↑ Back to top
Back In Stock Notifications helps you recapture lost revenue by notifying customers when your sold-out products are restocked. Back-in-stock alerts are a proven way to re-engage customers: Some studies suggest that up to 20% of the customers who receive a stock notification will return to complete their purchase. Here’s how the plugin works, in a nutshell:
- Customers who land on a sold-out product page are prompted to sign up with their e-mail.
- When the sold-out product becomes available, an automated notification is sent to all customers who joined the waitlist.
After installing and activating the plugin, make sure that out-of-stock products are visible in your catalog: Customers will not be able to sign up for back-in-stock notifications if out-of-stock products and variations are hidden. To confirm this:
- Navigate to WooCommerce > Settings > Products > Inventory.
- Make sure that Out of stock visibility > Hide out of stock items from the catalog is disabled.
Back In Stock Notifications supports Simple, Variable, Product Bundles, Simple Subscription, and Variable Subscription products only.
Signing Up ↑ Back to top
The plugin adds a small sign-up form next to the “Out of stock” availability status of sold-out products and variations:
To sign up for a back-in-stock notification:
- New (logged-out) customers must first enter their e-mail, and then click the Notify me button.
- Returning (logged-in) customers only need to click the Notify me button — the e-mail field is not added to the form in this case.
Note that it is only possible to sign up once per product/variation with the same e-mail.
The sign-up form is only displayed in product pages with an Out of Stock status. Signing up is not supported for products On Backorder.
If you would like customers to provide their explicit consent when signing up, the plugin lets you add an opt-in checkbox, along with your terms, before the Notify me button.
Under WooCommerce > Settings > Stock Notifications, you can also:
- Customize the form and form-button text.
- Display the number of customers who have already signed up.
When viewing a product or variation they have already signed up for, logged-in users see a short text with a link to manage their notification preferences instead of a sign-up button.
Receiving a confirmation
When a customer signs up, the plugin schedules and sends a confirmation e-mail that includes an opt-out link:
Enabling double opt-in
With Back In Stock Notifications, you can require customers to follow a verification link to complete the sign-up process.
Signing up as a guest
The plugin can be configured to create a new account for every guest who signs up with a new e-mail. Enabling this option is not recommended unless the list of users on your site is actively synced with an e-mail marketing platform.
It is also possible to require guests to log in before they can sign up. This is useful if checkout on your store is limited to users who fulfill specific criteria.
Signing up via catalog pages
The plugin lets you add a short message next to sold-out products in catalog pages, which informs customers that they can sign up to be notified when the product is back in stock. Customers who follow this link are guided to complete the sign-up process on the product page.
Signing up for variations
The extension is fully compatible with Variable products. When a customer signs up to be notified when a Variation is back in stock, the plugin:
- Stores the selected variation attributes.
- Displays them in confirmation and notification e-mails.
- Restores them when the customer returns to your shop by following the link in the notification e-mail.
Note: It is only possible to sign up once per variation.
Disabling sign-ups for specific products
In some cases, you may want to disable notifications for specific products; for example, products that you don’t plan to restock once they run out of stock. To do so:
- Navigate to WooCommerce > Products and locate the product you wish to edit.
- Edit the product.
- Go to the Inventory tab.
- Uncheck the Stock Notifications box.
Getting Notified ↑ Back to top
When a product or variation is restocked, the plugin:
- Prepares a list of customers who have signed up to be notified when the specific product or variation becomes available.
- Starts sending notification e-mails in batches.
By default, this process is triggered when the stock status of a product or variation changes from the Out of stock to the In stock status. However, it is also possible to define a minimum stock quantity for triggering notifications. This is useful if you have a few units of a product or variation that you want to restock, but don’t want to notify everyone on its waitlist.
To keep resource usage as low as possible, Back In Stock Notifications utilizes Action Scheduler – a robust task queuing system built into recent versions of WooCommerce. This allows the plugin to send thousands of notification e-mails without issues.
Note that when you restock a product or variation via the Products > Edit Product screen, the plugin adds a helpful notice to let you know how many signed-up customers will be notified in the next few minutes. The entire process is fully reversible: If you change the stock status/quantity back to its previous values while the system prepares to send the first batch of notifications, the process will be cancelled and no e-mails will be sent.
The e-mails sent to notification recipients follow the standard transactional WooCommerce e-mail format. The e-mail templates added by the extension are called:
- Back In Stock Sign-Up Confirmation
- Back In Stock Sign-Up Verification
- Back In Stock Notification
Their content can be customized under WooCommerce > Settings > Emails.
Opting Out ↑ Back to top
Returning, logged-in customers can view and manage their notification requests through a dedicated My Account > Stock Notifications page. From here, they can:
- Deactivate (unsubscribe from) individual notifications.
- Resend and cancel verification e-mails for unverified sign-up requests that require double opt-in.
- View notification activity.
Customers without an account can manage their notification preferences by following the “unsubscribe” link included in confirmation and notification e-mails:
- In Sign-Up Confirmation e-mails, the “unsubscribe” link makes it possible for guests to opt out/unsubscribe and deactivate the notification for the specific product they signed up for.
- In Sign-Up Notification e-mails, the “unsubscribe” link gives guests a way to opt out/unsubscribe and deactivate all active notifications associated with their e-mail address.

Viewing Insights ↑ Back to top
The plugin comes with a dedicated Dashboard that allows you to check its operational status, and quickly check key insights mined from your waitlists. Navigate to WooCommerce > Stock Notifications > Dashboard to:
- View the number of notification sign-ups and delivered notifications in the last 30 days, along with a 30-day bar chart.
- Find out which out-of-stock products in your catalog are in high demand right now, based on the number of customers who have signed up to be notified when they become available.
- Discover which out-of-stock products are the most long-awaited in your catalog, based on the number of days that have passed since the first notification sign-up.
- See which products in your catalog have received the highest number of sign-ups in the last week, month, or quarter, irrespective of stock status.
Combine this information with sales analytics data, and use it to:
- make better demand forecasts for products that are sold-out often,
- prioritize new orders or expedite deliveries for items in high demand,
- export customer details and send updates to those waiting for highly anticipated items via your favorite e-mail marketing platform.
Managing Notifications ↑ Back to top
Viewing Notifications ↑ Back to top
Notification requests for all products are listed under WooCommerce > Stock Notifications > Notifications. A notification can be Active, Queued, or Inactive:
- When a customer signs up for a back-in-stock alert, a notification is created and added here with an Active status.
- When the product/variation is restocked, the notification is Queued for delivery.
- As soon as the notification e-mail is sent to the customer, the notification becomes Inactive.
Notifications can be filtered by status, customer e-mail, or product/variation. To view a list of customers currently waiting for a product/variation to be restocked:
- Click the Active status on the top left of the list table.
- Search for the product/variation and select it.
- Apply to refresh the table.
It is possible to export the entire list, or filtered lists of notifications, in a CSV file. This is useful if you wish to import contact details in your favorite e-mail marketing platform/tool. To export notifications, click the Export button next to the “Notifications” page title.
Creating Notifications ↑ Back to top
