Communicate trade-offs and influence launch

Suppose the experiment shows significant lifts in notification success metrics (views, CTR, notification-driven actions) but a meaningful decrease in usage of accounts without notifications among multi-account users. How would you: (1) frame the trade-off for a PM and cross-functional partners; (2) estimate longer-term user value and potential churn risk (e.g., CLV impact, account-level activity diversity) to decide whether to launch; (3) propose mitigations (e.g., target only non-preferred accounts, frequency capping, per-person eligibility rules) and a phased rollout with guardrail thresholds; and (4) outline a monitoring plan post-launch to catch regressions and unintended behaviors?
