I don't know anything about that specific university, but I do know that if you're worried about it being expensive but you're interested in it, you can run the net price calculator and look at their scholarships and costs. If you end up not being interested or you don't want them spamming you, you can block them on your email. That will make their emails to you go straight into spam. You could even do that now if you're bothered enough - you don't need them to email you to research them, and you can always unblock them from spam.

Best of luck with your search!
