How do i get you to stop mailing to me?

There are many reasons, one is maybe he is busy at the point or another is something happened between you two and he might not want to talk.

You are getting e-mails that tell you when an answer of yours has been changed, you have a new message, and so on, and don't know how to stop it. There is a simple fix to this problem. In the blue...

You can block different emails from contacting you, yes.

I would say a stop line because if theres a stop sign most likely there is a stop line.... and in some places like my nabior hood people steal stop signs so watch for the line....

because is the law... to keep people safe.
