Short answer
Customer marketing is marketing aimed at existing customers to drive adoption, retention, expansion and advocacy rather than new acquisition. Activities include onboarding campaigns, product education, community programs and upsell offers. Because retaining and growing customers is often cheaper than winning new ones, customer marketing is important to recurring revenue businesses.
