This feature ensures that customers are alerted when out of stock items that they've expressed an interest in, become available to buy. Using this feature, site users can press the 'Email me when back in stock' button shown on relevant product pages and enter their email address, and they will then receive an automated email when the product's stock level is set to a value above zero. Etailers can view how many site users have requested a stock notification email per product, view the submitted email addresses, and edit the text of the automated email template.
Please note that it's not possible to apply notification functionality to selected products only - it can only be applied to all products.
This functionality is not available on standalone mobile sites.
