Sam’s Club CMO: What the Role Demands

The Sam’s Club CMO role is one of the more commercially demanding marketing leadership positions in American retail. Sitting inside Walmart Inc., Sam’s Club operates as a membership warehouse club competing directly with Costco and BJ’s Wholesale, which means the CMO is accountable not just for brand perception but for a metric that most retail marketers never have to defend: renewal rate. When your revenue model depends on members paying to shop with you, marketing has a direct line to the P&L in a way that most CMO roles do not.

Who Is the Sam’s Club CMO?

Ciara Anfield has served as Chief Member Officer and CMO at Sam’s Club since 2022. Her title is worth pausing on: Chief Member Officer. Not Chief Marketing Officer. That framing is deliberate and tells you everything about how Sam’s Club thinks about the marketing function. The member is the product. The member relationship is the business model. And the person leading marketing is accountable for that relationship from acquisition through renewal.

Before joining Sam’s Club, Anfield spent time at Walmart in various merchandising and strategy roles. That background matters. CMOs who come from brand agency backgrounds often struggle in retail environments where the commercial levers are immediate and visible. Anfield’s grounding in how the business actually works, what drives a member to renew, what makes a shopping trip feel worth the annual fee, gives her a credibility inside the organisation that pure brand marketers rarely have from day one.

If you want to understand how CMO roles like this one fit into the broader landscape of marketing leadership, the Career and Leadership in Marketing hub covers the structural pressures, tenure dynamics, and strategic expectations that define senior marketing roles across industries.

What Does the Sam’s Club CMO Actually Oversee?

The remit is broader than most people assume. On the surface, it looks like a retail marketing job: campaigns, promotions, seasonal activity, media spend. But the actual scope includes member acquisition strategy, retention and renewal programmes, the Sam’s Club app and digital experience, Scan & Go technology marketing, and increasingly, Sam’s Club Member Access Platform, which is the club’s retail media network.

That last one is significant. Retail media has become one of the fastest-growing advertising channels in the US, and Sam’s Club’s first-party membership data gives it a targeting capability that most media owners cannot match. When a brand buys media through the Member Access Platform, they are reaching verified purchasers with known income levels, household sizes, and purchase histories. The CMO does not just spend media budgets. She also, in effect, runs a media business that other brands pay into.

I spent years managing large media budgets across retail clients, and the shift from media buyer to media owner is not a small one. It changes how you think about data, about brand relationships, and about where marketing sits on the org chart. At Sam’s Club, marketing is not a cost centre. It is a revenue function in two directions: driving membership revenue and selling media inventory to suppliers.

The Membership Model Changes Everything About Marketing Measurement

Most retail CMOs are measured on sales, traffic, and brand metrics. The Sam’s Club CMO is measured on those things too, but the membership renewal rate sits above all of them. A member who does not renew is not just a lost sale. They are a lost relationship, a lost data point, and a lost media audience. The economics of membership businesses mean that retention is almost always more valuable than acquisition, and marketing has to reflect that priority.

This is where I think a lot of performance marketing thinking breaks down in membership contexts. When I was earlier in my career, I was obsessed with lower-funnel efficiency: cost per acquisition, return on ad spend, conversion rate. Those metrics felt clean and defensible. But they miss the point in a membership model. You can acquire a member cheaply and lose them at renewal. You can have a great conversion rate on a free trial and a terrible renewal rate twelve months later. The metric that matters is lifetime value, and lifetime value is built through experience, not through acquisition funnels.

Setting SMART goals in a membership business means anchoring on renewal rate and member lifetime value, not just new member acquisition numbers. The CMO who optimises for acquisition at the expense of experience is building a leaky bucket.

How Sam’s Club Is Positioning Against Costco

Costco is the dominant player in warehouse club retail. It has higher revenue, more locations, and a brand loyalty that borders on cultural phenomenon. Trying to out-Costco Costco would be a losing strategy, and Sam’s Club has been smart enough not to try.

Instead, Sam’s Club has positioned itself as the tech-forward alternative. The Scan & Go feature, which lets members scan items on their phones and pay without going through a traditional checkout, has become a genuine differentiator. Sam’s Club has also piloted AI-powered exit technology that removes the need for receipt checks at the door, a friction point that Costco members know well. These are not marketing gimmicks. They are genuine product improvements that the CMO then has to communicate in a way that makes them feel like reasons to choose Sam’s Club rather than features on a spec sheet.

This is the kind of positioning work I find genuinely interesting. It is not about spending more on brand advertising than the competitor. It is about finding the specific dimension where you can win and making sure your marketing amplifies that advantage rather than trying to compete on ground where you are already behind. Sam’s Club is not going to beat Costco on treasure hunt merchandise or rotisserie chicken mythology. But it can beat Costco on a shopping experience that feels built for how people actually want to shop in 2025.

Understanding what members actually experience in-club, beyond what they report in surveys, is where tools like real-time feedback capture become relevant for digital touchpoints. The app experience, the checkout flow, the renewal reminder sequence: these are all moments where member sentiment can be measured and improved.

The Digital and App Layer Is Now a Core Marketing Asset

The Sam’s Club app is not a companion to the shopping experience. It is the shopping experience for a significant and growing portion of members. Scan & Go runs through the app. Curbside pickup runs through the app. Member deals, Instant Savings, and personalised offers all surface through the app. The CMO’s remit therefore includes something that looks a lot like product marketing: working with technology and product teams to make the digital experience something members actually use and value.

I have seen this dynamic play out in agencies I have run. When a client’s app becomes a primary channel, the marketing team either gets closer to the product team or it gets marginalised. The CMOs who thrive in these environments are the ones who are comfortable in a product conversation, who can talk about user flows and friction points and session data, not just campaign metrics and brand tracking scores.

Anfield’s role sits squarely in that territory. She is not just running advertising. She is accountable for how members experience the brand across every digital touchpoint, which means the app, the website, the email programme, and the in-club digital infrastructure all fall within her orbit of influence if not direct ownership.

For digital experience optimisation, understanding how members interact with web and app interfaces matters enormously. Behavioural analytics platforms, including session recording and heatmap tools, give product and marketing teams a shared language for where experience breaks down and where it works.

Retail Media and the CMO as a Revenue Generator

Retail Media and the CMO as a Revenue Generator

Sam’s Club Member Access Platform has grown into a meaningful business in its own right. Suppliers pay to reach Sam’s Club members through on-site advertising, in-club screens, and off-site media targeted using first-party membership data. The CMO sits at the centre of this, because the data that powers the media network is the same data that powers member marketing.

This creates an interesting tension. The more aggressively you monetise member data through supplier advertising, the more carefully you have to manage member experience. Members who feel like they are being marketed at inside a club they are paying to shop at will not renew. The CMO has to balance the commercial opportunity of retail media with the member trust that makes the whole model work.

It is a tension I recognise from agency life. When I was running agencies, the clients who were most commercially sophisticated understood that short-term revenue extraction and long-term brand equity are often in direct conflict. The ones who treated their customer base as an audience to be monetised rather than a relationship to be invested in tended to see churn rates that eventually caught up with them. The Sam’s Club CMO has to hold that balance at scale.

Social distribution of content and offers is another lever in the mix. Getting the timing and targeting right on social media posts, particularly for time-sensitive Instant Savings promotions, is where tools like optimised posting schedules can make a measurable difference to reach and engagement without requiring a larger team.

The Millennial and Younger Member Opportunity

Warehouse clubs have historically skewed older. The membership model requires enough disposable income to pay an annual fee upfront, and enough household size or consumption to justify buying in bulk. For a long time, that pointed toward older, established households rather than younger ones.

That is changing. Younger shoppers, particularly millennials who are now well into their thirties and forties, are increasingly household decision-makers with families, mortgages, and a genuine interest in value. Sam’s Club’s technology positioning, the app-first experience, the Scan & Go convenience, resonates with this cohort in a way that a traditional warehouse club model might not. The CMO’s job includes making sure that positioning reaches younger audiences through the channels where they actually spend time, not just through the channels that have historically worked for warehouse club marketing.

There is also a conversion dynamic here worth understanding. A younger member who joins Sam’s Club in their early thirties and has a good experience is a member who might renew for twenty years. The lifetime value calculation is completely different from a member who joins at fifty-five. The CMO who understands that distinction will allocate acquisition budget very differently from one who is purely optimising for this year’s renewal numbers.

What Makes This CMO Role Different from Most

Most CMO roles are accountable for brand and demand. The Sam’s Club CMO is accountable for brand, demand, retention, digital product experience, and a media business. That is not a typical marketing brief. It is closer to what you would see in a subscription business or a platform company than in traditional retail.

The skills that make someone effective in this role are also different. You need commercial fluency, specifically the ability to read a P&L and understand how marketing decisions flow through to membership economics. You need technology comfort, because the app and digital infrastructure are not IT problems. They are marketing problems. And you need the political credibility to operate inside a large organisation, Walmart Inc., while maintaining the strategic autonomy to make decisions that are right for Sam’s Club specifically rather than just aligned with enterprise-wide priorities.

When I was building out agency teams and working with large retail clients, the marketers who struggled most in complex organisations were the ones who had deep expertise in one area but could not translate that expertise into the language of other functions. The finance team does not care about your brand tracking scores. The technology team does not care about your campaign creative. The CMO who can speak all of those languages without losing their marketing conviction is rare, and that rarity is part of why senior marketing roles at companies like Sam’s Club are genuinely difficult to fill well.

If you are thinking about what it takes to build a career that leads to roles like this one, the Career and Leadership in Marketing section on The Marketing Juice covers the full arc from early career decisions through to CMO-level accountability. The commercial grounding that the Sam’s Club role demands does not appear overnight. It is built through specific choices about where you work, what you measure, and how closely you stay connected to the business outcomes your marketing is supposed to drive.
