Never Lose a Sale When You're Out of Stock

StockAlert Pro lets your WooCommerce customers subscribe to instant email alerts when an out-of-stock product becomes available again. Instead of losing that sale forever, you capture the customer's interest and automatically bring them back the moment stock is restored — turning missed sales into revenue.
Works seamlessly with both Simple and Variable products, supports guests and logged-in users, and sends notifications automatically in the background without slowing down your store.

• A product goes out of stock — your customers see a "Notify Me" subscription form instead of the Add to Cart button.
• The customer enters their email and gives consent. They're added to the waitlist for that product.
• When you restock the product, the plugin automatically sends a notification email to all waitlisted subscribers.
• Customers click through and complete their purchase — sale recovered.

• Automatic Email Notifications – Subscribers are notified instantly when stock is restored, with no manual work required.
• Simple & Variable Product Support – Works at both the product level and the individual variation level.
• Guest & Logged-In User Support – Any visitor can subscribe, no account required.
• GDPR Compliant – Built-in consent checkbox with privacy policy link. No data collected without explicit opt-in.
• Rate Limiting – Protects your store from spam and bot subscriptions with built-in IP-based rate limiting.
• Secure Unsubscribe Links – Every notification email includes a one-click unsubscribe link using HMAC-signed tokens.
• Fully Customisable Emails – Customise the subject line, message, and sender name from the admin settings panel.
• Email Template Override – Developers can override the email template from their theme or child theme.
• Admin Dashboard – View all subscribers per product, export data, and manage subscriptions from a clean admin interface.
• Duplicate Prevention – The same email address cannot be subscribed twice for the same product.
• Translation Ready – Fully internationalised with a .pot file included. Compatible with WPML and Polylang.
• HPOS Compatible – Fully compatible with WooCommerce High-Performance Order Storage.
• Clean Uninstall – All data and database tables are removed cleanly on uninstall.
• Lightweight & Developer Friendly – No bloat, no upsells. Includes action and filter hooks for easy customisation.
