YITH WooCommerce Waiting List allows users to subscribe to a waiting list and be notified when the product is back available for purchase.
The integration between these two plugins allows you to edit all the information in “My Waiting List” from the “My Account” page (label, icon and content) using the admin panel of YITH WooCommerce Customize My Account Page. The only thing you need to do is to activate both plugins.
