How to interpret leakage severity

90-100% retention = Low leakage
Customer base is stable. Focus on loyalty and upsells.

80-89% retention = Moderate leakage
Leakage exists. Improve follow-up timing and inactivity tracking.

70-79% retention = High leakage
Revenue loss is meaningful. Prioritize re-engagement and churn workflows.

Below 70% retention = Critical leakage
Acquisition effort may be getting wasted. Retention must be fixed urgently.
