An Email notification is sent by Facebook account to your email account for different activities. For an active Facebook user, such email notifications are least important. These only fill email inbox and one has to spend more time deleting such notification emails. You can easily stop & disable such email notifications from Facebook settings page.
In this video demonstration I explained the procedure in a practical manner. Hookup your speakers and listen my voice narration while watching this video.
