what email is the specializaton unlock sent 2

I have been reading the threads regarding the specialization email, but my question has not been answered. Which email do they plan on sending the unlock code to? The email for my windows live ID is what i use to recover my account with on other peoples xboxs, so i assumed it woulc be that, but when I went to the contact information section of the xbox live website, the email address listed is different, and it is one that no longer exists. Please let me know what email they plan on sending it to, and what i should do if its the email address I have no access too. Thank you in advance.
