I'm from the Twin Cities and on the Dreshdae Cantina PvE Server (Sith).

That actually wasn't an email for the EGA. It was an email explaining when the EGA will begin, how the EGA email invites would be in waves depending on your preorder code redemption date, and to also pre-load the game client. It's basically telling you, be ready, but this is not your actual invite. EDIT: Beaten to the punch by Aviney.
