In Magento 2 under Stores->Configuration->Catalog->Inventory, there is an option for "Notify for Quantity Below" that can be set to 1, 2, 3, or whatever number you want. Under Magento 1, you could subscribe to the products RSS feed inside admin. The RSS feed would notify you, the admin, when the inventory would drop below the number you specified. In Magento 2 I don't see anywhere to subscribe to an RSS feed or to receive these notifications via email.
I've also searched extensively online for more information about this Magento 2 feature and nobody addresses how to receive this notification. Does anybody know how to receive the notification that is being set under "Notify for Quantity Below?"
Still no answer or solution? Is the configuration option and old value that was carried over from version 1 and is now obsolete?
It does not send email but it is available through RSS Feed. You need to go to Store > Configuration > Catalog > RSS Feeds and enable it first.
