I have used Zipwhip for several years, they have a very convenient feature that allows admin to save SMS Templates with placeholders so that we can repeatedly send the same message as needed.
For example, a Template named "Prescription Reminder":
Hi [First Name], it's time to update your prescription. Dr. Holcomb has availablility next week to see you. Let's get you booked!
This Template can be chosen from a dropdown and sent to multiple people with 1 click as an anonymous group message.
This feature does not exist in RingCentral, I have talked with support several times.
