E-mail address bound to account

Hello,
I and my friend decided to come back to WoW after few years. However, after such a long time our passwords have expired and were automatically reseted. I managed to find it in my box. However my friend is not sure which email he used since he cant find it on any of his. Could you guys please tell us which e-mail address is bound to account name: _____

After such a long time he is not sure if he used any other mail than his main...

Thank you.

Best regards.
