Remove updated event registrants from outreach lists quickly

Updated registrant rows can leave outdated contacts in outreach campaigns, causing duplicate invites to senior attendees. It removes matching entries so lists stay accurate before invites go.

Overview

When your registrant spreadsheet drifts out of sync with outreach campaigns, senior prospects can get duplicate invites and your team looks disorganized. This flow keeps campaign membership aligned to the latest spreadsheet changes so outreach accuracy improves and duplicate sends are prevented before your next invite run.
