Text Box is the best texting program out there, I believe! It works just like your phone. You can text anyone at anytime, and they can text back. It uses your office phone number, so you can tell residents and prospects they can call OR text you! The company will set up your contact list so that all of your residents are already entered by apartment number, building, and name. If you need to text an entire building, you can just text @bldg3 and it will send an individual text to all in building 3! It is great.
