Lifecycle Management & CRM Automation System

Turning disconnected email and SMS flows into a stage-based lifecycle system across acquisition, checkout recovery, onboarding, replenishment, and re-engagement.

I designed this CRM operating system and built it in Klaviyo together with my colleagues. It connected customer stage, decision barrier, next-action intent, product relationship, and channel role—while adapting automation journeys to different products and purchase contexts.

02 · Abandoned Checkout Design Logic

From customer hesitation to F1 and S1 recovery journeys

F1 and S1 are two different machines, each with its own recovery journey. The design runs from understanding why customers stop to giving each touchpoint a distinct conversion job.
