Guild Wars 2

I am wondering if the newsletter mail must be the same as the account mail for the chance to get an beta invite. The thing is that i have an old ISP mail that i use from gw1 till now and another gmail account that i actually use for mail. Can i register whit gmail or should i better change my account mail to gmail ?

I would assume that it needs to be the same as the account, seeing as they most likely also looks at the account standing and such when making the decisions about whom to invite.
