I went to preferences, but I didn't see any option to make my email private. I did a search on this site regarding this query, but I was not satisfied with the answer. It seems only moderators can view my email, but there should be an option to make my email public if in case it is private (I should be able to toggle between public and private). But there is no such option, so how do I make sure that my email is private?
Also I don't receive any email in my Gmail inbox if there are any unread messages at Stack Overflow.
