Email Roulette seems like a fun idea and you might wanna try it out ;)
"When you submit your message, it gets sent randomly to another player who has signed up. They have the option of responding to you or not; you won’t know who it went to unless they write back… so you better make it interesting!
Of course, it goes both ways. If you want to send emails, you have to receive them as well. When you get a message, it will tell you the username and email address of the sender. You can choose whether to write back or not - the sender does not get any information about you unless you choose to provide it."
