Appointment reminder message with a time range

How do I set up the reminder call to give the customer an hour window of arrival time instead of a set time that we would arrive. Example, I would want it to say, “This is your reminder for tomorrow between noon and one pm.” Instead of, “This is your reminder for tomorrow at noon.” Thanks!

There is no option to set this up directly. However, you can use the Message Designer to get what you want to achieve.

There are two times related to an appointment, one is the start time and the other is the end time. So you can think your appointment is for the possible arrive time. So for a 2:00 PM appointment, make it a 1:00 PM appointment with a one hour duration. With that, design a reminder message using the built-in Message Designer to say:

“This is your reminder for tomorrow between”
+
Appointment start time
+
“and”
+
Appintment end time.
