gstricklind on "[Plugin: WooCommerce - excelling eCommerce] Low Inventory Notification"

I've googled and searched for an answer to this, but have been unable to figure out what kind of notification low inventory uses.

Does it send an email notification when stock is getting low? Or does it just have a backend notification?
The wcdocs don't really specify.

Thanks.
