Unlike Facebook, Google plus has a good notification system. If you are using Google plus, you can verify it yourself. Every time your friends or followers in google plus add you in their circle(s), mention you in any comment, tag you within any photo or share any post with you; you will get a email notification at your email address related to your Google plus account.
While this feature makes a great sense for the notification purpose, over time, you would be exhausted with those bulk email messages. Why would you make your inbox cluttered with those junk emails while you can get the notifications in your Google+ account itself ?
So, it is better that you turn off the notifications in your Google plus profile to avoid the notification emails in your inbox.
