Shopper Marketing Agency for CPG Brands: In-Store and Digital Activations That Drive Sales

This guide covers what shopper marketing actually means for CPG brands in 2026, how to structure campaigns across in-store and digital channels, what to look for in an agency partner, and where most brands waste their budgets.

• Shoppers today move through digital and in-store touchpoints before buying. Pre-store digital activation drives measurable velocity lift when tied to a promotional calendar

• Trade promotion still accounts for roughly 15-25% of revenue at many CPG brands, with McKinsey putting the average near 20%, but most of that spend is not coordinated with digital

• Retail media (Amazon, Walmart Connect, Target Roundel) is now a standard line item in CPG digital budgets. US retail media ad spend grew 20.4% in 2024 to $52.3 billion and is on track to surpass $60 billion in 2025, per eMarketer

• The agencies getting CPG shopper marketing right can connect digital campaign periods to in-store velocity data, not just digital conversions

• Jetfuel specializes in the digital activation layer: paid social, retail media, and post-purchase Klaviyo flows that close the loop on retail sell-through

What Shopper Marketing Actually Means in 2026

Shopper marketing started as a trade discipline: endcap displays, coupons, temporary price reductions, and Sunday FSIs. Most of that toolkit is still alive in big CPG companies, but it has been expanded significantly by digital channels.

Today, shopper marketing covers everything that influences purchase behavior from the moment a shopper starts building their consideration set to the moment the product lands in their cart. That window now spans weeks, and it crosses digital and physical environments with no clean handoff between them.

Digital has added a pre-store influence layer that traditional shopper marketing could not reach. Paid social ads running in a specific DMA the week before a retailer promotion. Retail media placements on Amazon, Walmart Connect, and Target Roundel capturing shoppers actively browsing the category. Email flows triggered by a past purchase guiding a shopper toward a new SKU before their next store trip.

For CPG brands working with agencies, that pre-store window is where most of the interesting work now lives.

In-Store vs. Digital Shopper Marketing Activations

CPG brands need both layers. In-store activations are where most unit velocity happens at shelf. Digital activations drive the pre-store awareness and intent that makes those in-store moments work. The question is not which to choose but how to coordinate them.

The clearest way to think about it: in-store activations win the trial. Digital activations win the repeat. Brands that coordinate both with shared data build compounding velocity. Brands that run them in separate silos spend twice to get half the result.

How CPG Brands Structure Shopper Marketing Campaigns

The mistake most mid-size CPG brands make is treating in-store and digital as separate campaigns with separate agencies and no shared data. The trade team runs promotions through the retailer. The digital agency runs paid social without knowing the promotional calendar or which stores have display inventory.

The result: wasted spend. Awareness ads run in geos where the product has no distribution. The in-store promotion fires but there was no pre-store reach to prime the shopper. The digital agency reports strong CPM and CTR while sell-through at retail stays flat.

The brands getting this right build campaigns in three phases.

Pre-store (2-4 weeks before promotion). Paid social and digital video in the retailer's core DMAs. Meta prospecting against category buyer audiences. TikTok content targeting in-market shoppers. Retail media search placements for category and brand queries. The goal is getting the brand into the shopper's consideration set before they walk into the store.

In-store week. Secondary placement or endcap if earned. Trade price reduction at shelf. Sampling if the category benefits from trial as a conversion driver. The in-store team executes. Digital channels stay on to capture anyone still in-market who missed the pre-store phase.

Post-purchase (1-4 weeks after first purchase). Email or SMS flows triggered by the purchase event where first-party data exists. Loyalty offer for repeat or cross-sell. Retargeting ads serving replenishment messaging for lapsed buyers. This phase is where trial converts to retention.

Brands that run all three phases with shared data between trade and digital consistently see velocity lift that compounds over time. The ones running each phase in isolation burn trade spend on promotions that never build a loyal base.

What Jetfuel Brings to CPG Shopper Marketing

Our CPG work focuses on the digital activation layer: paid social, retail media, and post-purchase Klaviyo flows. We are not a traditional shopper marketing agency in the sense of managing trade promotion budgets with retailers. We are the team that makes digital channels work in coordination with whatever promotional calendar the brand's trade team is running.

Where we specifically differentiate: we build the feedback loop between digital spend and in-store velocity. If a paid social campaign runs in a retailer's core DMAs the week before an endcap promotion, we track whether velocity at that retailer moves relative to control markets. That signal tells us whether the pre-store spend is actually working or just generating clicks that do not land in-store.

The public benchmarks show how much this layer can move. Grocery TV's meta-analysis of 16 regression-controlled CPG sales-lift studies, controlling for price, seasonality, and store traffic, found an average 14% incremental in-store sales lift from digital shopper activation, ranging from 12% for gum and mint to 18% for produce. That figure is an in-store retail media benchmark rather than a pre-store paid social number, but it points at the same principle: when digital activation is measured against matched control stores instead of clicks, the velocity signal is real and large enough to plan around. We run the pre-store layer the same way, activated DMAs measured against control markets, so the read is causal rather than correlated.

The other gap we fill: post-purchase reactivation. Most CPG brands with any DTC presence or loyalty program have an under-automated Klaviyo account. The shopper who tried the product at a retailer is never contacted again because there is no systematic way to match the purchase event to an email address. We help build those flows.

Shopper Marketing Services CPG Brands Actually Need

Not every service category produces the same return for every brand. The right mix depends on distribution stage, category, and what first-party data the brand has built.

The most common failure mode: a CPG brand asks an agency to run shopper marketing before having the distribution or velocity to make retail media placements competitive. Retail media amplifies velocity once the product is on shelf. It does not build distribution. The sequence matters.

How to Choose a Shopper Marketing Agency for Your CPG Brand

The evaluation comes down to four things.

Do they understand retail velocity, not just digital metrics? An agency that can only report CPM and click-through rate is not equipped for CPG. Shopper marketing success is measured in units sold per store per week, not website sessions.

Do they have retail media buying experience? Amazon Advertising, Walmart Connect, and Target Roundel each have distinct auction mechanics, keyword behaviors, and campaign structures. An agency without hands-on experience on these platforms will learn on your budget.

Can they connect digital spend to in-store performance? This requires syndicated data access or retailer POS data. Agencies that can correlate digital campaign periods to velocity changes at specific retailer banners are running a fundamentally tighter program.

Do they work with your trade team, not around it? The best digital shopper marketing agencies treat the brand's trade team as a data source. Knowing the promotional calendar, the endcap schedule, and which retailers have incremental displays changes how paid media is allocated.
