I want the ability to send a series of messages in a Campaign based on a Custom DATE field.
For example...
  1. Send 1 Week BEFORE {birthday_date} @ 02:00pm ET (SMS)
  2. Send ON {birthday_date} @ 10:00am ET (VOICE)
  3. Send 1 Day AFTER {birthday_date} @ 11:00am ET (RINGLESS)
This way I can create a dynamic campaign based on the date in the custom field.
