Follow the format:
1. Account name.
2. Realm.
3. Current Email on your account, and the Email you want to be changed to.
4. Your IP address, indicate all of them.
5. Proof, that you really are the owner of the account, and Email ( If Microsoft have deleted your Hotmail/Outlook, you don't have to )
6. Decribe your problem, and why you want to change your Email
Pandawow staff can't give you the email. The best thing you can do is to log-in at pandawow.ru/en and at control panel you can see some letters of the email you used to create your game account (some letters are hiden for security reasons). By following the format you will make a "change email" request to pwow staff and hopefully they will change your email.
