What is WooCommerce Product Update plugin?
WooCommerce does not include native back-in-stock or price change notification functionality. When a product goes out of stock, interested customers have no way to register for an alert within WooCommerce core — they must manually check back. Several plugins add this capability to WooCommerce stores.
Back-in-stock notification plugins add a subscription form to out-of-stock product pages. Customers enter their email address to be notified when stock is restored. When the product stock status changes back to In Stock, subscribed customers receive an automated email.
Price drop notification plugins similarly allow customers to watch a product and receive an alert when the price falls below a threshold or changes. Both types of notifications help recover revenue from customers who were interested but did not purchase due to availability or price.

Free vs Premium
Free options exist with basic back-in-stock notification functionality. Paid options like YITH Back in Stock or WooCommerce Waitlist add waitlist management, customisable email templates, subscriber analytics, integration with email marketing platforms, and priority support. For stores where back-in-stock notifications are a key revenue recovery tool, the paid options offer better control and reporting.
Common Problems & Fixes
Back-in-stock notification emails are not being sent when I restock a product.
Notification sending depends on the product stock status changing from Out of Stock to In Stock in WooCommerce. If you updated the stock quantity but did not change the stock status, the trigger may not have fired. Go to the product, then Inventory, and verify the stock status shows In Stock. If the status changed correctly but emails were not sent, check your WordPress email configuration — the emails are sent through wp_mail() which requires a working SMTP setup. Test with a Send Test Email function if the plugin includes one.
The back-in-stock subscription form is not showing on my product page.
Most back-in-stock plugins display the subscription form by hooking into WooCommerce template hooks on single product pages, typically near the Add to Cart button area. If the form is not showing, verify the product is actually set to Out of Stock status — the form only appears for out-of-stock products. Also check for theme conflicts where a custom single product template overrides the standard WooCommerce hooks that the plugin uses for form injection.
Customers say they signed up for notifications but never received them.
Check the subscriber list in the plugin admin to confirm the customer email was actually saved. If subscriptions are being saved but emails are not arriving, the issue is email deliverability — the notification emails are going to spam or being rejected. Check your SMTP configuration and ensure notification emails are sent through an authenticated SMTP service rather than PHP mail(). Ask the customer to check their spam folder and whitelist your store email address.
Customization & Developer Notes
How do I set up back-in-stock notifications for specific product variations?
Quality back-in-stock plugins support variable products and allow customers to subscribe to specific variations — for example, a specific size and colour combination. The subscription form should appear when a customer selects a sold-out variation combination. In the plugin settings, verify that variation-level notifications are enabled. This requires the plugin to correctly identify which variation triggered the out-of-stock status and track subscriptions per variation, not just per parent product.
Can I customise the back-in-stock email template?
Most paid back-in-stock plugins include email template customisation. The template editor typically allows changing the email subject, header image, body text, and button styling. Free plugins often use a fixed email template. For stores where branding consistency matters, a paid plugin with template control is worth the investment. Always send yourself a test notification after customising the template to verify it renders correctly across email clients.
Frequently Asked Questions
Do back-in-stock notifications work for digital products?
Yes, if digital products in your WooCommerce store are configured with stock management enabled. Digital products can have stock quantities set and Out of Stock status like physical products. If a digital product has limited seats, licences, or download slots, back-in-stock notifications work the same way. Digital products that are set to unlimited or not tracking stock cannot go out of stock and do not need back-in-stock notifications.
Can I export the subscriber list from a back-in-stock plugin?
Most paid plugins include a subscriber list export. This gives you a CSV of customer emails who have subscribed to specific products. This data is useful for targeted email campaigns to interested customers beyond just the automated notification. Handle this data carefully — these customers have subscribed to product notifications, not general marketing emails, so GDPR consent applies if you want to use their email for other purposes.
What happens to subscriptions if I permanently discontinue a product?
Subscriptions for discontinued products remain in the plugin database until manually deleted. If you permanently remove a product, it is good practice to delete the associated subscriptions from the plugin admin to clean up the database. Most plugins allow bulk deletion of subscriptions by product. You may also want to send a final email to subscribers letting them know the product has been discontinued, which is a courtesy that maintains customer trust.
Is there a free WooCommerce back-in-stock plugin that works well?
Several free options exist on the WordPress plugin repository. Back In Stock Notifier for WooCommerce by codewoogeek is a frequently updated free option. Waitlist Woo is another. Feature sets in free versions are more limited — typically covering basic email notifications without advanced subscriber management or template customisation. For a small store with modest needs, free options are a reasonable starting point before investing in a paid solution.
