Add source tag for contacts removed from lists

Your marketing list removals leave contacts without source context, causing mis-segmentation and duplicate outreach. The workflow tags those contacts so campaign managers can segment accurately same day.

Overview

When subscribers are removed from lists, source attribution often disappears and segments break, making outreach less precise. This flow finds the matching contact and tags them with the removal source so campaign managers and marketing ops can re-segment and avoid duplicate outreach within the same day.
