Once you have NutshellMail set up, you should not need Facebook notification emails. Unfortunately, we are not allowed to turn off your notifications for you.

Go to your Facebook profile and click on the Account Settings menu item within the Account tab on the toolbar. Select the Notifications Tab. Uncheck the boxes to stop receiving messages, then scroll to the bottom of the Notifications page and click "Save Changes" button. Congratulations, you have just uncluttered your inbox.
