It is better to stick on your normally doing. I know from experience that pretty interesting email is dangerous. I clicked on an interesting email once and got more and more spams since then. Spammers are skillful today, they know how to make their emails not go to bulk folder. No matter how interesting the email you got is, please don't reply. Hope you haven't yet. I understand your curiousity if that email address really exists, but remember, curiousity can cost you a lot.
