SaaS Startup: 120% Email Revenue Growth

+120% Email Revenue

Challenge, solution, and results

01 · Challenge

Growing SaaS platform with 12K users but declining retention.

  • No onboarding sequence (new users didn't understand the product)
  • No re-engagement (inactive users churned silently)
  • No upgrade messaging (free users didn't know about premium)
  • Generic broadcast emails

40% annual churn, leaving significant revenue on the table.

02 · Solution

We mapped 12K user journeys into new, active, inactive, paying, and at-risk segments, then built onboarding, activation, upgrade, and win-back flows with feature-led creative.
