Back In Stock Notifier for WooCommerce | WooCommerce Waitlist Pro

Every out-of-stock product is a lost sale waiting to happen. Back In Stock Notifier for WooCommerce captures those visitors instead of losing them. It shows an email subscription form on out-of-stock products, then automatically emails every subscriber the moment the product is restocked.

Why store owners choose this plugin

• Built for scale. Restock emails are sent through a background process engine. Even with 10,000+ subscribers on a single product, notifications go out reliably. No server crashes, no timeouts, no duplicate emails that loop-based plugins suffer from.
• Works out of the box. Activate the plugin and the waitlist form appears on out-of-stock products immediately. No setup required.
• Native WooCommerce emails. The subscription confirmation and restock notification emails use the WooCommerce email system, so they match your store branding and are fully customizable under WooCommerce > Settings > Emails.
• Trusted by 20,000+ stores worldwide.
