Class segments let you build lists of students who have taken or are currently enrolled in your workshops and multi-session classes, right inside the same platform where you sell tickets and run your calendar. Because enrollment sits next to your event data, you can pull a segment without exporting spreadsheets or stitching together a separate mailing list.
This matters because a student who finished one class is the easiest sell for the next one, and the easiest audience for a related event. Segments turn that relationship into something you can actually market to, instead of information that sits unused in a roster.
