Retrieving Account Trouble

I'd like some help! I haven't played in a bit, and the AndApp session expired. I'm trying to retrieve the e-mail I used for the account through AndApp and I'm not really sure how to go about it. I have my account ID and name, but I don't know how to fetch the e-mail. I believe I rerolled a few times, so the e-mail would've definitely changed.

If anyone can help, it would be really appreciated.
