Understand what opt-in means after the first session
For teams that need a more credible view of consent, engagement and retention.
A careful interpretation
People who opt in may already be more engaged. We document that selection effect and use appropriate cohorts, pre-consent behaviour and sensitivity checks before drawing conclusions.
Study outputs
- Cohort definitions and data quality review
- Retention and engagement curves by permission journey
- Channel and use-case analysis where available
- Limitations, confidence and practical implications
The result is a decision aid, not a claim that permission alone causes retention.
