I’m not getting my emails from @privaterelay.appleid

Hey, so i’m having this problem I need to verify my email on one app, but I chose to hide my email when I first logged in so I didn’t know where I would get the email. I did some reseach on apple website and it told me to go to setting<(my name)<Sign in with apple<and then find the app and delete it from there so I did. But I still didn’t got any email, so 2 days in trying to figure it out and today I found out that my email was in a folder called “spam” but it was the email from 2 days ago, so it’s invalid now and I don’t know where I get those emails now, I hope someone from you can help me soon, thank you.
