From time to time Google decides to tell me that I might know some people by their G+ profile from whom I only ever contact via email. (I don't, and don't want to, know or have to do anything with their G+ account)
Case in point: I have this person
firstname.lastname@example.org with whom I exchanged a few emails about 1-3 years ago. Now he's showing up in my email.
Similarly, I'm sure he must be getting same email about me.
I repeat, I don't want these people whom I only contact via gmail to find my G+ profile.
What do I do to make that sure?
