We want to enable the Mobile Opt-In feature in TNEW but we don't know of any great options to send out text messages to our patrons. In addition to sending out texts to lists of patrons, ideally we would be able to send out a 'Welcome' text after enrolling as well as the option to opt-out as a reply to the text message. Does anyone have any recommendations or have any experience with this that they'd be willing to share?
