I really hope you did not attach your name to all of those emails. Double digit cold-emails to any school is just too much. People talk and that type of email bombing will get you labeled a pest, at best, or even worse a zealot who lacks social skills and judgment.
I know you're trying to do an informal test, but you are likely shooting yourself in the foot in the process. Students talk, admissions people talk, and they often talk to one another. You don't want your app to come across their desk and for them to think, "Oh this is the stalker who indiscriminately emailed everybody and their mama for no damn reason." Because trust me, they will not see any reason for you to contact that many people under any circumstances. JMO.
