Email used for KYC/AML

I have a question, maybe someone has faced the similar issue.

The email I’ve used during ICO phase is not available for me anymore.
Now, I have to register myself for KYC/AML.

Can I use another email for that purposes?
Will I pass successfully an entire registration process in that case?

Thanks for any suggestions, especially if you know for sure what will happen and have been in this situation yourself.
