I agree with everyone else. It's always a waste of energy to read into an email. And some schools have a policy of only disclosing acceptance information via certain channels. I worked for the study abroad office at my school, and no one was allowed to discuss information re: program status over the phone, email or in person. Everyone had to either wait for a letter in the mail, or else in extenuating circumstances program directors could disclose info to the applicant directly.
If you really have a lot of concerns, or if you've been accepted somewhere, but are waiting to hear from your reach school, give them a call and see if you can get anything more substantial that way.
And with a phone call, at least you get a tone of voice to read into, rather than a dead email.
