Google+ sends a ton of email notifications, and they can become quite annoying. It's also hard to figure out how to turn them off, so we thought we'd help you there!
1. Click on your photo at the very top right corner of the Google + page. This will pull up a drop down box.
2. Click on Account Settings.
3. Click on Google+ in the column all the way to the left of the screen.
4. Uncheck whatever notifications boxes you no longer wish to receive.
