I would like to send mass text messages to clients who are not engaging in their program. People who are not engaging in the program are obviously not on the app. i need to be able to send them a text message, encouraging them to re-engage. Otherwise I will never reach them. It is inevitable that 100% of people will fall along the way. Whey they are in a bad place, they are not using their app - but you can reach them immediately and anywhere with a text. Give it some consideration.
