The Post-Sale Power Play: How Customer Marketing Drives NDR Across the Full Funnel
Most marketing teams are optimized for pipeline and new logo acquisition. But in SaaS, the metric that defines long-term growth isn’t new business, it’s Net Dollar Retention.
In this session, we’ll unpack why customer marketing is one of the most misunderstood and underutilized growth levers in modern B2B organizations. Kevin will share how to transform customer marketing from a reactive advocacy function into a full-funnel growth engine that drives adoption, retention, and expansion.
We’ll explore how to build prescriptive onboarding programs, create a scalable advocacy flywheel, align cross-functional teams around shared OKRs, and use customer insights to power both post-sale and pre-sale motions.
If your board conversations are increasingly focused on retention and expansion, this session will give you a practical playbook to move beyond churn mitigation and into sustainable growth.
For years, most marketing teams have been optimized around one thing: pipeline.
But when you step into a board meeting today, the conversation often sounds different. Leaders want to know about churn. Expansion. And the metric tying it all together: Net Dollar Retention (NDR).
In a recent CMO Series conversation, Kevin Lau, VP of Global Customer Marketing at Freshworks, shared why customer marketing is becoming one of the most important growth levers in modern SaaS organizations and why so many companies still misunderstand it.
Below are the biggest insights from the discussion.
Customer Marketing Is More Than Advocacy
Many organizations still treat customer marketing as a narrow function focused on case studies and references.
According to Lau, that definition is incomplete.
In traditional B2B organizations, customer marketing and customer advocacy are often treated as the same thing. In reality, advocacy is only one part of a much larger lifecycle strategy.
True customer marketing spans the entire customer journey. It supports both:
- Pre-sale efforts, by providing proof and credibility for prospects
- Post-sale engagement, by helping customers adopt, succeed with, and expand their use of a product
When done well, it creates a flywheel where successful customers drive both retention and new business.
Why Net Dollar Retention Matters More Than Ever
In SaaS, growth is not just about acquiring new customers. It is about keeping and growing the ones you already have.
Net Dollar Retention has become a critical indicator of company health because it measures how much revenue grows within the existing customer base. A company with 110–120% NDR can grow even without acquiring new customers.
This makes retention and expansion just as important as acquisition.
Yet many organizations still focus most of their marketing investment on demand generation. Lau argues that marketing has a major opportunity to influence the other side of the equation.
“Customer marketing can play an even bigger role in driving NDR and long-term growth,” he explained.
The Most Important Window for Retention: The First 30–90 Days
One of the strongest predictors of long-term retention happens immediately after the sale.
According to Lau, the first few months of a customer’s journey are critical for adoption and long-term success. If customers quickly see value and feel supported during this period, they are far more likely to stay.
Marketing can play an important role here by helping design structured onboarding programs.
Examples include:
- Welcome email series and onboarding content
- Product training resources and education programs
- Clear communication around support channels
- Guided journeys that help users reach value faster
These efforts ensure customers know how to use the product and where to find help before frustration sets in.
Measuring Customer Health Requires More Than CSAT
Many companies rely heavily on surveys like CSAT or NPS to understand customer satisfaction.
While useful, Lau notes that these metrics often function as lagging indicators. They capture feedback after problems occur rather than identifying risks earlier.
A more complete view of customer health should combine multiple signals, including:
- Product usage and adoption data
- Relationship strength with account teams
- Feedback from executive business reviews
- Support history and escalation patterns
By bringing these signals together, companies can build a more accurate 360-degree picture of customer health and identify churn risks earlier.
Advocacy Still Plays a Critical Role
Customer advocacy remains one of the most powerful growth engines available to marketers.
When customers share their experiences publicly through case studies, events, or community engagement, they create credibility that marketing alone cannot manufacture.
But many advocacy programs fail because they rely on repeated requests to the same group of customers.
Lau recommends building more structured programs that focus on mutual value. That means understanding what customers want in return.
For many advocates, the benefits include:
- Professional visibility through speaking opportunities
- Direct access to product teams and early features
- Networking with peers and industry leaders
When advocacy programs are designed around customer value, they become sustainable instead of transactional.
Customer Marketing Is the Bridge Across the Organization
Customer marketing naturally sits at the intersection of multiple teams.
It touches:
- Sales
- Customer success
- Product
- Support
- Marketing
Because of this position, the function can serve as an orchestrator across the organization.
Customer marketers often collect valuable insights from customer feedback, community interactions, and advocacy programs. Those insights can help product teams improve features, help support teams reduce recurring issues, and help marketing teams strengthen messaging.
When aligned around shared goals like retention and expansion, these cross-functional efforts become a powerful driver of growth.
How AI Is Changing Customer Marketing
AI is also beginning to reshape post-sale marketing strategies.
One of the biggest immediate benefits is the ability to analyze large volumes of customer insights. Teams can use AI to extract themes from interviews, analyze call transcripts, and identify proof points for marketing campaigns.
Looking ahead, Lau believes AI will also enable more predictive engagement.
With better data and automation, teams will be able to:
- Identify customers likely to become advocates
- Trigger personalized lifecycle campaigns
- Recommend next best actions for account teams
In other words, customer marketing will become more proactive and data-driven.
The Future of Growth Is Customer-Led
As SaaS markets become more competitive, companies can no longer rely solely on new customer acquisition.
Retention, expansion, and advocacy are becoming central to sustainable growth.
Customer marketing sits at the center of that shift.
By connecting onboarding, education, customer insights, and advocacy into one cohesive strategy, marketing teams can help create what Lau describes as the ultimate goal: customers for life.
