Back in Stock is a Craft CMS plugin that allows anyone to register interest on out of stock products. If they do and the product becomes re-stocked an email will automatically be sent to all interested emails with a link prompting them to purchase.
Visit the Back in Stock Plugin page for all documentation, guides, pricing and developer resources.
