About this plugin
CartEngine Back in Stock Alerts for WooCommerce helps recover sales from out-of-stock products. Instead of losing customers forever, let them subscribe with one click and automatically email them when you restock.
No complicated setup. No bloat. Just a clean “Notify Me” form, reliable email delivery, and a simple subscriber dashboard right inside WooCommerce.
How It Works
- A visitor lands on an out-of-stock product page
- They enter their email and click “Notify Me When Available”
- You restock the product (manually or via import)
- The plugin automatically sends a back-in-stock email to all subscribers
- The customer clicks the link and completes their purchase
Key Features
Back-in-Stock Notifications
Automatically triggered when product stock status changes to “in stock” — no manual work needed. Emails are sent in batches of 50 with configurable throttle to protect your server.
AJAX Subscription Form
The “Notify Me” form submits without a page reload. Displays directly on the product page — no extra pages, no popups, no friction.
Variable Product Support
). When you restock a particular variation, only subscribers to that variation receive the notification.
Shortcode [safw_stock_alert]
Place the subscription form anywhere using the [safw_stock_alert] shortcode. Supports product_id and variation_id attributes for full flexibility.

View and manage all subscribers from WooCommerce → Stock Alert Subscribers. Filter by status (active, notified, unsubscribed), sort by date or email.
Spam & Abuse Protection
Built-in IP-based rate limiting (5 subscriptions per IP per hour) keeps your list clean without any configuration.
Unsubscribe Link in Every Email
