My girlfriend has quite a few email addresses for various reasons. Last night she began signing up for MBA, filled out every apart from her Bank Details as her bank doesn't support IBAN from the USA yet.
A week later, she now has a Bank Account with IBAN support, but since there is no email from Merch thanking you for the sign up, she has no idea which email address she used to sign up with..
Can you send an email out when you register please? Currently it seems like a black hole and nobody knows what's going on
