Nostalrius Begins - Quality wow vanilla realm (1.12)

hi i dont use my old email address coz i cant access it is there a way to change it if i provide other info ? any help on this would be great.
thanks.

There is no (and probably never will be) a way to change your email of the game account.

The only option right now to change the email is by creating a new elysium account by using a new email. You can create the transfer token on the website too, you dont "need" access to your nostalrius registered email.
