In this short tutorial, we will see the steps required to turn off email notifications on Nexus 7 when a new message arrives. This option is not available as part of General setting, so If you have configured more than one mail accounts in the Email app then you need to make changes to each account separately.
Step 1: Launch Email app on Google Nexus 7.
Sep 2: Now select menu option available on the Right hand side and select Settings from the menu list.
This should display a screen with General Settings along with other configured Email accounts.
Step 3: Select any one of the account then Options available next to ADD ACCOUNT.
Step 4: Scroll down to NOTIFICATION SETTINGS and make sure to unmark the check box with caption as Email notifications.
This should disable both display notification and sound notification for that email account. Repeat the above steps to turn off Email notifications for other accounts.
