RestockX

RestockX recovers lost sales on your WooCommerce store by letting interested customers subscribe to restock alerts for out-of-stock products. When a product comes back in stock, every confirmed subscriber is notified automatically by email — turning missed sales into completed orders.

Customers click the “Notify Me” button on any out-of-stock product, enter their email, and confirm the subscription. Store owners get a clean admin dashboard to manage subscribers, customize emails, and export data.

Features

• “Notify Me” button on out-of-stock products — displayed automatically on single product pages, with support for both simple and variable products (per-variation detection).
• Automatic back-in-stock emails — subscribers are emailed as soon as a product or variation’s stock status changes to “in stock”.
• Double opt-in confirmation — optional email confirmation protects your list from fake or mistyped addresses. Can be enabled or disabled.
• One-click unsubscribe — every alert email includes an unsubscribe link and a List-Unsubscribe email header, so subscribers can opt out anytime.
• Customizable button appearance — change button text, tooltip, colors, font, icons, padding, margin, border width, color, and border radius from the admin area.
• Customizable email template — personalize the back-in-stock email with placeholders for product name, product URL, site name, and unsubscribe link.
• Stock notification threshold — choose the stock quantity at which notifications should be triggered.
• Subscriber management — view subscribers with product, email, date, and status (pending / confirmed / unsubscribed); delete entries in bulk.
• CSV export — export the full subscriber list for reporting or external marketing tools.
• Dashboard statistics widget — see total notifications, unique products, and unique subscribers at a glance on the WordPress dashboard.
• Alternative product suggestions — after subscribing, customers are shown up to 5 in-stock alternatives from the same categories or tags.
• Rate limiting — subscription requests are limited per email address to prevent abuse and spam.
• Email deliverability friendly — sender address is kept domain-aligned (with automatic Reply-To handling) so alert emails don’t get dropped by recipients’ providers.
• Translation ready — fully translatable via WordPress.org translate.wordpress.org.

How it works

1. A customer visits an out-of-stock product and clicks the “Notify Me” button.
2. They enter their email address and submit the form.
3. Depending on your settings, they either confirm via a double opt-in email or are subscribed instantly.
4. When you restock the product, RestockX automatically emails all confirmed subscribers with a link back to the product.
