Every out-of-stock product page is a missed opportunity — unless you capture the demand before it walks away. Back In Stock Notifier – WooCommerce Waitlist Pro solves that exact problem by replacing the dead end of a sold-out item with an email subscription form that turns interested shoppers into a waiting list you can convert the moment inventory returns. Built by webstock for WooCommerce stores, this plugin automatically emails subscribers when a product is restocked, so a temporary stockout never becomes a permanent lost sale. With over 1,523 sales on CodeCanyon and more than a decade of continuous updates, it is one of the most established waitlist solutions available for WordPress e-commerce.
Key Features
- Advanced WooCommerce waitlist functionality — when a product goes out of stock, the plugin displays an email subscription form directly on the product page, capturing buyer intent at the exact moment it exists.
- Automatic back-in-stock email notifications — as soon as inventory is replenished, every subscriber on that product’s list receives a notification email, converting waiting visitors into probable customers.
- Simple and variable product support — works at both product level and variant level, so shoppers can subscribe for the specific size, color, or configuration they actually want.
- Guest and member compatibility — both logged-out visitors and registered users can subscribe, and for members the email field is pre-filled automatically to reduce friction.
- Per-product subscriber lists in the backend — each single product page in the admin displays its own subscriber list, making it easy to see exactly who is waiting for what.
- Subscriber count for priority restocking — the number of subscribers per product tells you which items are in highest demand, enabling data-driven restocking decisions.
- Export waitlist as CSV — download subscriber data for each product or from the master log for use in external email campaigns or CRM tools.
- Manual notification sending — send notification mails to selected subscribers on demand, and optionally clear the notify list after a successful notification.
- Duplicate email protection — the same email address cannot be added twice to the same product’s waitlist, keeping your data clean.
- Customizable mail subject and message — tailor the notification email content from the admin settings, including product image, product price, and product title shortcodes.
- Unsubscribe option in subscription mail — every subscription email includes an unsubscribe link, supporting GDPR-friendly list management.
- Translation ready and WPML compatible — build multilingual waitlists and send localized notification emails.
- Customizable error and success messages — control message text, position, color, and styling to match your store’s branding.
- WooCommerce Subscriptions compatibility — tested against WooCommerce Subscriptions v2.0.15 for stores selling recurring products.
Who Is This For? Use Cases
E-commerce Store Owners
Any WooCommerce store that sells products prone to selling out — limited editions, seasonal items, handmade goods, or high-demand electronics — benefits immediately. Instead of losing a visitor who lands on an out-of-stock page, you collect their email and notify them the moment the item returns. The subscriber count per product also gives you a clear demand signal for restocking priorities.
WooCommerce Agencies and Developers
Agencies building client stores can deploy Back In Stock Notifier – WooCommerce Waitlist Pro as a ready-made, out-of-the-box solution rather than developing custom waitlist logic. The plugin is translation ready, WPML compatible, and supports custom CSS, which makes it straightforward to match a client’s design system. With a long, well-documented update history, it is a low-risk addition to any WooCommerce build.
Fashion and Apparel Retailers
Variable product support at the variant level is particularly valuable for clothing and footwear stores, where a specific size or color can sell out while others remain available. Shoppers subscribe for the exact variant they want, and the notification email can include the product thumbnail and price to bring them straight back to the purchase page.
Subscription-Based and Recurring Product Sellers
Because the plugin is compatible with WooCommerce Subscriptions, stores selling recurring or subscription products can capture waitlist demand when a subscription tier or product is temporarily unavailable, then notify subscribers when it becomes purchasable again.
Marketing and Growth Teams
The CSV export and master log turn your waitlist into a marketing asset. You can export subscriber emails for launch announcements, VIP restock alerts, or segmented campaigns — all built from genuine purchase intent rather than cold traffic.
Bloggers and Content-Led Stores
Stores that drive traffic through content and reviews often send visitors to product pages that are temporarily sold out. Capturing those visitors with a waitlist form keeps the relationship alive and gives you a second chance at the sale.

Frequently Asked Questions
Does Back In Stock Notifier work with variable products and specific variations?
Yes. The plugin supports both simple and variable products and can operate at the product level or the variant level. This means a customer can subscribe specifically for the size, color, or configuration that is out of stock, and the notification email will reference the correct variation. Version 13.1.0 also fixed a display issue where the notifier form field appeared twice on variable products.
Can I customize the notification email and add my own branding?
Yes. The mail subject and message are fully customizable from the admin settings, and you can choose between an HTML email template or the default WooCommerce template. Shortcodes are available for the product title, product URL, product image, and product price, so the notification email can include a clickable product thumbnail and current price. Each subscription email also includes an unsubscribe option, and the footer and unsubscribe text can be customized as well.
Is the plugin compatible with the latest WordPress and WooCommerce versions, and does it support WPML?
Yes. Version 13.1.0 was tested with WordPress 6.8.3 and WooCommerce 10.3.3, and the plugin has maintained compatibility with each major release since 2014. It is also compatible with High-Performance Order Storage (HPOS), WooCommerce Subscriptions v2.0.15, and WooCommerce Stock Manager. For multilingual stores, Back In Stock Notifier – WooCommerce Waitlist Pro is WPML compatible and translation ready, including the notification emails themselves.
Final Verdict
Back In Stock Notifier – WooCommerce Waitlist Pro is a mature, focused solution to one of the most expensive problems in e-commerce: the sold-out product page. Rather than sending interested buyers away, it captures their email, tracks demand per product, and automatically brings them back when inventory returns.
