DIRECT ANSWER
Customer acquisition cost (CAC) is the total sales and marketing spend required to acquire one new paying customer, calculated as total acquisition spend divided by new customers acquired in the same period. It is a primary efficiency metric for growth teams, typically evaluated alongside LTV to determine whether customer economics are sustainable. In Lifecycle Marketing specifically, this means Maintain a real-time lifecycle stage model (MQL, SQL, trial, active, at-risk, churned) per contact and Trigger stage-appropriate nurture sequences automatically on stage transitions — all of which Hadrian's Lifecycle Marketing Agent executes autonomously on your live data.
What customer acquisition cost (cac) means in Lifecycle Marketing
