Back in Stock Notifications & Waitlist

A customer who doesn’t leave empty-handed

A sold-out product is usually a lost sale – the customer goes looking elsewhere and never comes back. Restock Alerts turns that moment into a saved contact instead: the customer leaves their e-mail and comes back on their own once the product is available again.

A sold-out product is a customer who won’t come back

Without a waiting list, you have no way to reach customers interested in a specific, temporarily unavailable product – and manually noting “who asked about X” doesn’t scale once traffic picks up.

A waiting list that keeps track of stock for you:

A button in place of “Add to cart”

On a sold-out product (including a sold-out variation, e.g. a size), the button replaces “Add to cart” and opens a popup with a form. You can also show the form directly on the product page, add a “Notify me” link to the product list, or place it anywhere with the [restock_alert_form] shortcode. Optionally works for backorder products too.

A form that matches your store

Set the heading, description, button text and message, the accent colour and the corner-rounding style. The form can ask for a name and quantity, require GDPR consent, and limit sign-ups to logged-in customers only.

Automatic e-mail when a product is back in stock

The plugin detects stock changes – including from imports and wholesaler integrations – and sends a “the product is available again” e-mail with the product card. The customer gets a confirmation once they sign up. Both e-mails are edited in WooCommerce settings and go out in the language the customer signed up in.

Example: only 5 units of a hoodie in size M come back in stock, and 12 people are on the list — the plugin notifies only the first 5 by sign-up order and requested quantity, and the rest wait for the next delivery.

Fair notifications and a minimum stock level

If fewer units come back than there are people waiting, only as many customers get notified as there are units – by sign-up order and requested quantity. You can also set a minimum stock level before notifications start going out, so nobody gets an “it’s back!” e-mail only to see “sold out” again a moment later.

Stats and spam protection

WooCommerce → Waiting List shows every sign-up with filters (waiting, notified, bought after notification), search, CSV export and manual sending. The product list gets a column showing the number of people waiting, and the plugin tracks how many sign-ups turned into a purchase. A hidden honeypot field, a minimum fill time, a sign-up limit per IP and optional Cloudflare Turnstile protect against spam without breaking your page cache.

Works wherever your store works

Sending runs in the background (Action Scheduler) with a per-minute e-mail limit – useful on hosting with sending restrictions. Every e-mail has an unsubscribe link, and you can export or delete customer data with WordPress’s privacy tools. The plugin is HPOS-compatible, works with the block checkout, WPML and Polylang.

You’re up and running in a few minutes

Installation takes a few clicks: upload the ZIP, activate the licence and set up the form’s content. The “Delivery diagnostics” tab shows e-mail status, the queue and the last mail-server error, with a test-send button.
