I understand the issue of letting people opt out of text messaging, but we need a system we can use with prospects. Asking a prospect to opt-in to texts from an agent they don't know will not work. It makes texting in prospecting campaigns impossible. Even with existing clients it is burdensome. Clients do not want to opt in. Adding "Text STOP to opt out of text messaging" once a month or something could work if it is really necessary, but sending a second text message is not acceptable.
