This plugin creates an input field on the single product page, if the product is out of stock under the summary. The user can enter an email address to subscribe for the product alert. 
This email address is saved to the database within a new table. If the product stock changed from out of stock, the user will get an email with a custom message. This message can be edited on the option page.
Warning: The plugin doesn’t work 100% with variable products.
