MLX Back In Stock Notifier for WooCommerce allows your customers to opt-in for email notifications when their desired out-of-stock products are replenished.
Designed strictly to WordPress and WooCommerce coding standards, this plugin provides a seamless frontend experience for customers and a powerful backend management interface for store administrators, without bloating your database.
<h3>Core Features</h3>
<ul>
<li>Automated Notifications: Customers receive an instant email the moment a product’s stock status changes to “In Stock”.</li>
<li>Customer Management: Adds a native “Stock Notifications” endpoint to the WooCommerce My Account page where users can view and remove their waitlist items.</li>
<li>Admin Waitlist Dashboard: View an aggregated list of all out-of-stock products that have customers waiting.</li>
<li>Alternative Product Suggestions: Manually email waiting customers to suggest a different, in-stock product using WooCommerce’s native AJAX product search and customizable message templates.</li>
<li>Performance Optimized: Uses native WordPress metadata API and caching. No custom database tables.</li>
<li>Fully Compatible: Officially declares compatibility with WooCommerce High-Performance Order Storage (HPOS) and Cart/Checkout Blocks.</li>
<li>Clean Cleanup: Automatically removes waitlist data if a product is permanently deleted from the store.</li>
<li>Enterprise-Grade Scalability: Built on WooCommerce Action Scheduler. Whether you have 10 or 10,000 customers on a waitlist, emails are processed safely in the background in batches. Your site will never freeze or crash when updating stock.</li>
<li>Full Variable Product Support: Works flawlessly with product variations (e.g., sizes, colors). Customers can subscribe to specific out-of-stock variations, and the waitlist UI updates instantly as they select different options from the dropdowns.</li>
<li>Performance & Security Optimized: Zero inline JavaScript or CSS. All assets are properly enqueued and localized, ensuring maximum compatibility with caching plugins (like WP Rocket) and strict Content Security Policies (CSP).</li>
</ul>
