Add canceled subscribers to churn segment and remove active

Cancellations aren't updating lists, so you keep emailing ex-customers and distorting metrics. It moves them to a canceled segment and removes actives before the next send.

Overview

Untracked cancellations lead to wasted sends and skewed campaign metrics. This flow ensures cancellations are reflected in your audience within minutes, so campaign managers can suppress ex-customers and protect deliverability before the next broadcast.
