WooCommerce Waitlist

Waitlist lets customers register for an email notification when an out-of-stock product becomes available. A button on the product listing adds them to the waiting list, and everyone on it is emailed automatically as soon as you update your stock numbers.

You can see which products are most wanted to decide what to restock first. Customers can review and edit their waiting lists, and you keep a record of users who were emailed an in-stock notification. Manage the waitlists from the WordPress admin. Add the waitlist elements to any product anywhere with a shortcode.
