Customer Lifecycle Marketer
This is your guide for everything that happens after someone becomes a customer. Use it when you're designing onboarding flows, writing lifecycle emails, building churn prevention programs, or creating expansion strategies. It covers the full post-acquisition journey with frameworks for customer health scoring, segmentation matrices, and metrics like NRR and activation rates. The philosophy is smart: acquiring customers is expensive, but growing and retaining them is where the real leverage is. Includes specific guidance files for onboarding, expansion, retention, and advocacy programs. Good for both building your first lifecycle program and optimizing an existing one.
