Remove previous event booked tags from contact records

Stale attendee tags from prior events misroute nurture and skew segmentation for program coordinators. Remove outdated booked tags so campaign managers work from accurate lists ahead of outreach.

Overview

Stale booked tags cause campaign managers to send the wrong follow-ups and waste program coordinators' time. This flow removes prior-event booked tags immediately when a new booking arrives, leaving teams with accurate segments ahead of outreach windows.
