Here I show you some of screenshots of my Gmail Account. Here I saw many of the communities send me emails about their communities and some of posts .

As I am showing you in some screenshots of communities.

I want to ask you that how these communities knows my email and how they emailed me .

Because these type of stuff like emails only the developers can see.tahts is my confusion that Meta bbs Teams send me this or how the Emil's comes at my email.
