What does the “Start Initial Feedback Sequence” button do?

The “Start Initial Feedback Sequence” button allows you to start the built in Feedback Email Sequence for the first time, to any contact or segment of contacts, that have been uploaded to the software individually, or via CSV file, that have never been added to the Initial Feedback Request Sequence.  

These contacts are tagged with the “Not Invited Yet” status, and are the only contacts that will allow this button to be activated.
