Hi,
A delay before save the date texts being sent out would be amazing for when patients make appointments but maybe move around the time/date quickly. In these relatively frequent scenarios, an appointment is made, save the date is sent, but the patient quickly decides they want another day or time and get another text for the now correct time.

If they didn't get the message for a time we can set, like an hour, any changes we made in person can be completed before they receive the text.
