Customer Retention: Mailchimp vs Hadrian
DIRECT ANSWER
Customer retention is a company's ability to keep existing customers purchasing or subscribed over a defined time period. It is measured as the percentage of customers who remain active from the start to the end of a period. High retention compounds revenue growth because each cohort's lifetime value extends without additional acquisition spend. Mailchimp addresses customer retention as a tool you prompt manually; Hadrian's agents execute it continuously on your live brand data under your approval gate.
What customer retention means in practice
The retention rate formula is: ((Customers at end of period − New customers acquired during period) ÷ Customers at start of period) × 100. Tracking this monthly and by acquisition cohort reveals whether new segments retain as well as older ones — a critical diagnostic for expansion-stage companies.
For marketing teams, customer retention is a lever that needs consistent, ongoing execution — not a one-off task. The question is whether your tooling runs it continuously or requires manual effort each time.
