Notify your customers whenever your “Out of Stock” products shift to “In Stock”. The Out-of-Stock Notification is a Magento extension which allows the store owners to indicate the users on their product update via the user's e-mail. The extension when installed enables the store owners to pop-up a message box for the Out-of-Stock products, indicating the customer to enter their email id to get notified on the product that is back in stock. The store owners can personalize the email message by editing the default email template provided in the admin. The extension is simple to install and configure with an easy back-end.
