Email Associated with Account?

Hi I just recently wanted to get back into the game. It says I need to authenticate via email but the problem is while I remembered my username and password I do not remember what email I signed up with for this account. I tried to go to user control panel and looked around but can't at all find what the email I used for this account was so I can go find it and authenticate so I am able to log in. Can you tell me where to find it or maybe privately message me my email address with this account? Thank you.
