CartEngine Stock Alert Pro is a WooCommerce plugin designed to provide back-in-stock notifications with added demand intelligence for online store owners. It addresses the common issue of losing potential sales when customers encounter out-of-stock products by enabling them to subscribe for notifications when items are restocked. Unlike standard stock alert solutions, this tool not only sends notifications but also delivers analytics on customer demand and tracks the effectiveness of notifications in driving actual purchases.
The plugin features an AJAX-powered subscription form that appears automatically on out-of-stock product pages, allowing customers to subscribe without a page refresh. It supports variable products, letting subscribers pick specific variations. Its "Smart Stock-Limited Notify" system ensures that if the number of subscribers exceeds available restocked units, only the earliest subscribers (using a FIFO queue) are notified, with others remaining in the queue for future restocks. Store administrators can choose from three email templates—minimal, branded with a logo, or visual with product details—and every notification includes a one-click unsubscribe link for compliance and convenience. The double opt-in process and optional consent checkbox help meet GDPR requirements, and the plugin also supports WordPress privacy features such as data export and erasure, along with configurable data retention.
For store owners, Stock Alert Pro provides a demand analytics dashboard showing which products have the most subscribers, notification history, and revenue recovered from restock alerts. Conversion tracking is built in, allowing merchants to see the full funnel from subscription to purchase, including which notifications lead to sales. Additional features include admin notifications for new subscribers, batch sending with throttling to avoid spam filters, social proof widgets displaying how many people are waiting for a product, CSV export of subscriber data with filters, IP-based rate limiting to prevent spam, and customizable appearance settings through WooCommerce.
0+, and has been tested with major WooCommerce-compatible themes. It is offered as a one-time purchase for $49, with instant download and no subscription required. Optional renewal is available for continued updates after the first year.
