Design a subscription service journey covering Discovery (marketing channels, referrals), Free Trial (signup, initial usage, feature exploration), Conversion (upgrade prompts, pricing decisions, payment setup), Active Usage (regular engagement, feature adoption, value realization), Renewal Decisions (usage evaluation, price sensitivity, alternatives consideration), and Churn/Retention (cancellation attempts, win-back offers, exit surveys, reactivation campaigns). Map engagement levels, satisfaction metrics, billing touchpoints, customer support interactions, and identify moments of highest churn risk and retention opportunities.
