How to check email address in iRacing?

I just opened an iRacing account using the 12-month promocodes given to new iRacing members. Everything was going fine but when I tried to log into my account it says wrong credentials. I tried to reset my password but didn't get an email. I think I misstyped my email when opening the account. I sent an email to iRacing Support but considering supports mails take al long time to respıond I came here. How can I log in or find my correct credentials?
