We're looking for a community texting system, who do you use?
We currently have Forrent.com Community Messenger. For some reason within the past year when we send a mass message to all of our residents, it does not go to everyone. We're in Texas.
Please help!

Aptexx was great when I used it because it let us text prospects and residents. I also think Rent. has a new texting solution

Text box is great.

We use AppFolio as our PM software, and they include texting. It works fairly well but needs drastic improvements. Two major issues are: 1. Mgmt is unable to send images via text. 2. The notification of a text message only goes to the last person who sent out a text message. Ie) If the leasing agent sends a text to Bob and then Bob decides to send a text to the Property manager weeks later, the leasing agent receives the notification and not the PM. I think it would be best for either everyone in the office to receive the text or each person to have their own dedicated texting number.
