The Seven Habits of a Highly Effective Customer Marketer (part two)

The second habit of a highly effective customer marketer: build long-term relationships. Stop treating post-sale as the end of marketing's job — it's where retention, LTV, and expansion revenue live, and the data shows that's where best-in-class companies compound.

Part 2: Build long-term relationships

Introduce these 7 mindset adjustments to your daily activities to become an effective customer marketer and prove your programs are worth their weight in gold — literally.

In the previous post in this series we focused on laying the foundations for a customer-led growth culture, and the need for customer marketing to adopt and evangelize a new, cross-functional approach. This week, I'd like to highlight one of the pillars of a Customer-Led strategy that is often referred to as creating "customers for life."

In the B2B industry this type of marketing strategy is even more r/evolutionary because the relationship between marketing and the customer was traditionally something that started to dwindle as the hand-off to Sales, Support and Success was made.

But it's the age of the customer, and we now know that marketing to customers is far more than a "nice to have" initiative. Customer marketing is delivering an upsurge in previously-uncharted marketing metrics like retention, revenue, and lifetime value.

Why long-term relationships are now a financial imperative

The economics of B2B growth have flipped. New-logo acquisition is more expensive, buying cycles are longer, and buyers rely more on existing users than on vendor messaging. Consider:

• McKinsey's analysis of 100+ B2B SaaS companies found Net Revenue Retention is the single metric most correlated with enterprise value — top-quartile valuation multiples averaged 24x revenue vs. 5x for the bottom.
• Companies with the most sophisticated value-realization and adoption journeys produce NRR roughly 7 percentage points higher than peers with basic practices (McKinsey, 2025).
• Best-in-class B2B SaaS firms generate more than 50% of new ARR from expansion, not new logos.
• 56% of B2B buyers consult existing users before purchasing — 71% for enterprise deals (TrustRadius, 2024).

Translation: the post-sale relationship is now the single biggest source of growth in B2B. That's customer marketing's turf.

So, our habit for today is to shift your mindset and behavior to serving a long-term game

Don't settle for a short funnel. Place as much (or even more) importance on the post-sale relationship as you would on generating demand, and the customer-led magic will begin to flow in.

1. Build long-term relationships. Stop optimizing for the first conversion and start optimizing for the fifth renewal. The compounding economics of Customer Lifetime Value dwarf the one-time gain of a signed contract.
2. Treat customers as the demand channel. Your best-fit prospects want to hear from people who look like them. Peer proof — reviews, references, case studies, community voices — outperforms vendor-authored content at every buying stage (G2, 2024).
3. Operate from a single source of truth. A shared view across Marketing, Sales, and CS is what makes "long-term" actually work. See how Team Dashboards embed that view into the CRM.
4. Map relationships, not just accounts. Champions leave, buying committees change, and the person who signed the contract may not be the person who renews it. Key Account Marketing is relationship hygiene at scale.
5. Invest in community. Community and advocacy programs turn one-to-one relationships into one-to-many growth loops.
6. Listen, then act. Voice of Customer programs only pay off when the signal actually changes something downstream — a roadmap, a campaign, a CS play.
7. Measure what compounds. Retention, NRR, LTV, advocacy participation, reference velocity — these are the numbers that CFOs fund.

What this looks like in practice

A long-term relationship mindset shows up in the calendar. You schedule customer conversations with the same urgency as pipeline meetings. You build nurture journeys that extend past year one. You make sure Sales is paid to grow accounts, not just to close them. You treat advocacy like an always-on channel, not a once-a-quarter ask — which is exactly why we wrote how to scale advocacy without burning out your best customers.

The marketers who do this don't just keep their customers longer. They build the kind of category-defining businesses that analysts cite as examples.

Frequently asked questions

What is customer marketing?

Customer marketing is the discipline of marketing to and with existing customers to drive retention, expansion, and advocacy — the post-sale half of the revenue equation. See the full definition in our Guide to Customer Marketing.

Why is building long-term customer relationships a customer marketing responsibility?

Because the post-sale relationship now generates the majority of B2B SaaS revenue (expansion, renewal, advocacy-driven new business). Someone has to own it, and customer marketing is the function closest to the signal.

What metrics prove customer marketing's value?

Net Revenue Retention, Customer Lifetime Value, advocacy participation rate, reference velocity, expansion pipeline generated, and review volume are the numbers that tie customer marketing activity to revenue.
