Colleges and Universities?

I'm a sopre, and took the PSAT in the fall. I guess they're all graded now, and since I filled in my email address on the form when i took the PSAT, I've received emails from the CollegeBoard site that was connected to the PSAT. Since then, I've gotten emails from Mercer, NYU, Georgia Tech, Emory, Washington and Lee, and the University of Evansville. I got all excited and stuff then I started thinking they probably send these to nearly everyone, right?
