Currently Chilipiper supports sending unique reminders to attendees if they do not RSVP for their scheduled meeting, but it does not include branching logic that ensures the attendees will only recieve one type of reminder. As a result, if an attendee does not RSVP for their meeting, they can receive the general reminder messages AND reminder messages unique to those that don't RSVP. There would be benefit to providing branching logic to allow users to control that.
