Effective Retention Email Strategies
1. Monitor engagement drops
Users who stop logging in are at risk. Trigger re-engagement campaigns when activity declines.
2. Address failed payments
Involuntary churn from payment failures is preventable. Dunning emails recover 30-50% of failed charges.
3. Celebrate milestones
Anniversary emails, achievement notifications, and usage milestones reinforce value.
4. Gather feedback
NPS surveys and feedback requests show you care and surface issues before they cause churn.
