What is Customer Marketing?

Customer marketing encompasses activities like advocacy programs, reference management, case study creation, review generation, and customer communications designed to deepen relationships and maximize customer lifetime value.

Customer Marketing vs. Demand Generation

While both functions drive revenue, they operate on different sides of the customer lifecycle:

Demand Generation focuses on acquiring new customers. It owns top-of-funnel activities like content marketing, paid advertising, events, and lead nurturing. Success is measured by pipeline generated and new logos acquired.

Customer Marketing focuses on existing customers. It owns post-sale activities like onboarding communications, advocacy programs, customer communities, and reference management. Success is measured by retention, expansion, and proof assets generated.

The two disciplines should work together. Customer marketing creates the proof (case studies, reviews, references) that demand generation uses to convert new prospects. When aligned, they create a flywheel: happy customers generate proof, proof converts new customers, new customers become advocates.

Core Customer Marketing Activities

Customer marketing teams typically own four key areas:

Customer Advocacy — Identifying and nurturing customers who are willing to publicly support your brand. This includes managing advocacy programs, coordinating speaking opportunities, and recognizing top advocates.

Reference Management — Building and maintaining a pool of customers who can speak with prospects during the sales cycle. This requires tracking reference availability, matching references to opportunities, and preventing reference fatigue.

Case Studies and Proof Assets — Creating customer stories that demonstrate real-world results. This includes written case studies, video testimonials, ROI data, and customer quotes for sales and marketing use.

Review Generation — Driving customers to share feedback on third-party platforms like G2, Gartner Peer Insights, and TrustRadius. Strong review profiles build credibility during buyer research.

Why Customer Marketing Matters

Customer marketing has become essential for three reasons:

Retention drives profitability. Acquiring a new customer costs 5-25x more than retaining an existing one. Customer marketing programs that improve engagement and satisfaction directly impact the bottom line.

Expansion is the growth engine. For SaaS companies, 70-80% of revenue often comes from existing customers through upsells, cross-sells, and renewals. Customer marketing supports expansion by keeping customers engaged and aware of new capabilities.

Proof fuels the pipeline. B2B buyers trust peers more than vendors. Case studies, reviews, and reference calls are among the most influential content types in purchase decisions. Customer marketing creates this proof.

Frequently Asked Questions

How is customer marketing different from customer success?

Customer success focuses on helping individual customers achieve their goals with your product—driving adoption, solving problems, and preventing churn. Customer marketing focuses on mobilizing successful customers for business impact—creating proof, generating references, and supporting expansion. The two teams work closely together, with customer success identifying happy customers and customer marketing activating them.

When should a company invest in customer marketing?

Most B2B companies benefit from dedicated customer marketing once they have 50+ customers. Before that, customer marketing activities are typically handled by product marketing or customer success. Signs you need customer marketing: sales is asking for references you cannot provide, case studies are outdated, and reviews are sparse.

What skills does a customer marketer need?

Strong customer marketers combine relationship-building skills with marketing execution. They need empathy to work with customers, project management skills to coordinate across teams, writing ability for case studies and communications, and analytical skills to measure program impact.
