Ah, so you use GMail. They definitely have a spam folder, and are notoriously aggressive about putting legit e-mails in there.
E-mail support anyway, and explain the situation. Their reply might get through, with a verification code.

...Then what is this topic about?
NGAAAAAAAAAAAAAAAAAH!! I SAID THIS IS NOT MY GMAIL ACC---
JUST DELETE IT! THIS IS MY WORST MISTAKE I MADE!!!!!!!!!!!!!!!!!!
So this is about two different e-mails? In that case, make sure you're using the primary e-mail connected with your itch.io account. This is necessary for example when talking to support.
