Google+ users may not be aware of the settings that allow you to select which notifications you receive for various postings or other activities. I became aware of this when I first started using Google+ and noticed I was getting many email notifications. I customized my settings to reduce this email traffic. Below are two screen shots showing where to find the settings.
First get the menu by hovering your mouse pointer over Home under the colorful Google+ at the upper left corner. Click on Settings near the bottom of that menu.
A new window opens with lots of settings to manipulate. Scroll down to the area shown in the screen shot below where you see Notifications.
Each category under Notifications will expand when you click on it. There you can choose which notifications to receive and which communication path they should use.
The topic of Notifications is also covered in this Google posting. Be sure to browse the other settings for other things you may like to customize.
