  • ＋ SMS growth and engagement — Some reviews credit the app with growing subscriber lists, improving customer engagement, and supporting sales activity.
  • ＋ Strong overall app quality — A few merchants describe the app as useful, sophisticated, or better than other SMS platforms they have tried.
