Engagement scores feel modern. They also travel poorly across programmes. A login drop two months before an annual renewal may mean nothing if members only visit when a handbook ships. An NPS dip can lag a price change that already finished its cancellations.
Open rates on renewal emails fail when the real decision happened on a printed invoice or a payroll deduction the member never sees in their inbox.
When we run a Churn Signal Diagnostic, each candidate must show lead time against voluntary exits and coverage across the cohort — not just a correlation in a slide. Signals that fire for everyone, or only after the cancel is logged, drop off the shortlist.
Better candidates are often dull: skipped gift renewals, expired corporate seats, consecutive payment retries, or a plan downgrade that still leaves the member “active” in a vanity dashboard. Dull signals are easier for a desk to act on before the renewal window closes.
