How do I turn off email notifications on my Gmail app on Android? I'm using an LG Tribute phone which I recently purchased for Virgin Mobile.  I have Gmail installed and by default, whenever I get an email, it generates a notification (in my case a buzz since I have my phone on vibrate).  

How do I turn off notifications entirely for my Gmail app (don't want any sounds when I receive an email)?
In the Gmail app itself:


Slide open the hamburger (3-lines) menu and tap on "Settings". 
Then tap on the Gmail account that you want to disable notifications for. 
In here deselect the "Notifications" check box.
