SMS mailing android, why get banned?

Question

Android

I plan to create a program for an android phone to send messages.
The mailing list is not spam, for employees about the status, there will be no complaints. Well, although, of course, someone can make a bad guy =)))
Approximately 100 pieces a day.
Will there be a ban, what are the consequences? Are there apps for this?

Answer 1

Googled my calls.
