Best Ecommerce Marketing Agencies for 2026

An ecommerce marketing agency in 2026 does more than buy ads. It is expected to grow a direct-to-consumer business across acquisition and retention, manage creative at the volume modern platforms consume it, and tie spend back to unit economics the finance team will defend. The work now spans Meta and Google, TikTok and Amazon, retail media, email and SMS, landing-page conversion, and the measurement plumbing that connects all of it to revenue.

Choosing one is hard because the surface metrics lie. Platform ROAS still looks healthy while contribution margin erodes, because signal loss from iOS and cookie deprecation pushes more credit onto channels that were going to convert anyway. Creative demand has outpaced what most brands can produce, so agencies that cannot ship volume stall. And the retention side of the business, the lifecycle email and SMS that actually compounds LTV, is too often run as a separate vendor from the acquisition team that determines who enters the funnel in the first place. Add Shopify, marketplaces, and a sprawl of storefronts, and the question of who can run all of it well gets genuinely difficult.

Our point of view at QRY is simple to state and harder to practice: the job is to grow contribution profit and incrementality, not platform-reported ROAS. A dollar of media is only worth spending if it produces a sale that would not have happened otherwise, and the agencies worth hiring can prove which dollars clear that bar. This list is built around that lens.

How to use this list

Read the descriptions, not just the names. These nine agencies serve different brands at different stages, and the right one depends on your growth economics, your channel mix, and how integrated you need retention to be with acquisition. Several of these shops also appear on our broader best paid media agencies roundup, but here we are looking specifically through a DTC ecommerce growth lens rather than a general media one.

If you want a deeper diligence framework before you sign anything, we wrote a separate guide on how to choose a paid media agency that walks through the questions worth asking on a pitch call.

1. QRY

QRY is an independent paid media agency built around the principle that the job is to grow contribution profit, not platform-reported ROAS. For ecommerce brands, that means full-funnel paid media across Meta, Google, TikTok, Amazon, and CTV; performance creative built to feed a continuous test pipeline; lifecycle and retention integrated into the same media plan rather than siloed with a separate vendor; and the measurement infrastructure (incrementality testing, media mix modeling, and platform data together) that ties every spend decision back to contribution margin.

Headquarters: Jersey City, NJ

Year Founded: 2016

Team Size: 20–50

Key Services:

• Full-Funnel Paid Media
• Performance Creative
• Incrementality Testing and Media Mix Modeling
• Lifecycle and Retention Marketing

Why Choose QRY:

Most ecommerce agencies will grow your platform ROAS while contribution profit quietly flattens, because platform-reported numbers reward channels that claim credit for sales that were already coming. QRY is built to refuse that. The practice centers on incrementality: which media dollar genuinely produced a sale, where diminishing returns actually begin for your specific brand, and what the next dollar is worth. Senior practitioners own the client relationship directly, so the people doing the strategic thinking are the people you talk to, and the way that work is structured is described in our paid media operating model.

We're a fit for: DTC brands that want a partner accountable to contribution profit and incrementality, with senior practitioners on the relationship. We're not a fit for: brands that only want last-click ROAS managed cheaply.

• Consumer Packaged Goods
• Financial Services
• Healthcare

2. Common Thread Collective

Common Thread Collective is an ecommerce growth agency based in Santa Ana, California, working with direct-to-consumer brands across paid media, creative, web, and content. It is a Shopify Plus partner known for a structured forecasting and growth methodology that frames media planning around projected revenue rather than channel-level optimization alone. The agency focuses on DTC brands doing roughly $5M to $200M in annual online revenue, with a model that connects acquisition spend to growth economics from the start.

Headquarters: Santa Ana, CA

Year Founded: 2012

Team Size: 50–200

Key Services:

• Paid Media (Meta, Google, TikTok)
• Performance Creative and Content
• Web and CRO
• Revenue Forecasting and Growth Modeling

Why Choose Common Thread Collective:

The draw here is the forecasting discipline. Rather than starting from last month's ROAS, the agency works backward from a revenue model, which forces the kind of contribution and growth conversations many DTC brands skip until it is too late. The combined paid, creative, web, and content scope suits brands that want fewer vendors managing the funnel. Brands looking for a pure media-buying specialist with no interest in the web or content layer may find the model broader than they need.

Industries:

• Direct-to-Consumer Ecommerce
• Apparel and Lifestyle
• Consumer Goods

3. Pilothouse

Pilothouse is a full-funnel DTC performance agency based in Victoria, BC, with in-house media buyers running Meta, Google, TikTok, Amazon, and YouTube alongside in-house creative production. The model is structured so buying and creative sit under the same roof, which shortens the loop between what is tested and what is shipped. The agency has reported managing significant cumulative revenue for its clients across the DTC brands it works with.

Headquarters: Victoria, BC

Year Founded: 2019

Team Size: 50–200

Key Services:

• Paid Social and Paid Search
• Amazon and YouTube Advertising
• In-House Creative Production
• Full-Funnel DTC Performance

Why Choose Pilothouse:

What stands out is the breadth of in-house buying across the major DTC channels at once, which matters for brands whose growth is not a one-platform story. Creative and media operating together tends to produce a faster iteration cycle than an agency that outsources production. That same full-funnel breadth is the trade-off: a brand that only needs one channel run exceptionally well may not need the whole apparatus. Pilothouse also appears in our roundup of best performance marketing agencies, and the ecommerce read on it is its multi-channel in-house buying depth.

Industries:

• Direct-to-Consumer Ecommerce
• Consumer Goods and Lifestyle
• Food and Beverage

4. MuteSix

MuteSix is a Los Angeles DTC performance agency, now part of Dentsu's iProspect, offering omnichannel media buying across Meta, Google, TikTok, YouTube, and Amazon with strong in-house video and creative production. It is a TikTok partner and leans heavily on video as a growth lever for consumer brands. The agency was founded in 2015 and was acquired by Dentsu in 2019, bringing broader platform relationships and network resources to its DTC client base.

Headquarters: Los Angeles, CA

Year Founded: 2015

Team Size: 200–500

Key Services:

• Omnichannel Paid Media (Meta, Google, TikTok, YouTube, Amazon)
• In-House Video Creative Production
• DTC Performance Marketing
• Email and SMS Marketing

Why Choose MuteSix:

If video creative is the bottleneck on your growth, MuteSix's in-house production depth is the reason to look here. Being part of a larger group brings broader platform relationships and resourcing, which can help brands scaling into multiple channels at once. The flip side of group ownership is worth diligencing directly: ask who staffs your account day to day and how senior that team is. For DTC brands where video volume and omnichannel buying are the constraint, the fit is clear.

Industries:

• Direct-to-Consumer Ecommerce
• Beauty and Personal Care
• Consumer Lifestyle

5. Brighter Click

Brighter Click is a DTC ecommerce paid-media specialist based in Raleigh, NC, running paid campaigns across Meta, Google, TikTok, and Pinterest alongside performance creative and UGC sourcing. The agency positions its work around contribution margin and inventory flow rather than ad-account metrics alone. It serves growth-stage DTC brands that need both the media buying and a creative engine under one roof.

Headquarters: Raleigh, NC

Year Founded: 2019

Team Size: 20–50

Key Services:

• Paid Social and Paid Search (Meta, Google, TikTok, Pinterest)
• Performance Creative Strategy
• UGC Sourcing and Production

Why Choose Brighter Click:

The reason this one earns a place is the stated focus on contribution margin, which is the right unit for a growth-stage DTC brand and not where most specialists of this size start. Pairing paid media with UGC sourcing addresses the creative-volume problem directly rather than treating it as someone else's job. As a smaller specialist, the practical question is capacity at scale, so a brand approaching significant spend should pressure-test how the team grows with the account. For a growth-stage brand that needs paid plus a creative engine in one place, the profile fits well.

Industries:

• Direct-to-Consumer Ecommerce
• Health and Wellness
• SaaS and Tech

6. Black Propeller

Black Propeller is a Bel Air, Maryland paid media agency running paid search, paid social, Amazon, SEO, and performance creative, with a reported $100M-plus in annual ad spend under management. Founded in 2012, the agency has a center of gravity in search and social acquisition for growth-stage and mid-market brands across ecommerce and lead-generation categories. The scope covers Google, Meta, Amazon, and broader search and social channels.

Headquarters: Bel Air, MD

Year Founded: 2012

Team Size: 20–50

Key Services:

• Paid Search (Google, Microsoft)
• Paid Social (Meta, TikTok)
• Amazon Advertising
• SEO and Performance Creative

Why Choose Black Propeller:

Black Propeller's strength is disciplined paid search and social execution for brands whose growth is mostly an acquisition-efficiency problem. The Amazon and SEO capabilities round out a search-led ecommerce program where intent capture matters as much as demand generation. Retention is less central here than at the lifecycle-heavy shops on this list, so a brand whose growth depends on LTV expansion should weigh that. Brands that lead with paid search may also want to compare it against our best PPC agencies list.

Industries:

• Ecommerce
• Lead Generation and Services
• Consumer and B2B

7. Structured Agency

Structured Agency is a Marina del Rey, California ecommerce agency running paid social (Meta, TikTok, Google), email and SMS lifecycle, and performance creative, with acquisition and retention managed together rather than as separate engagements. The agency was founded in 2018 and has built depth in beauty, fashion, food and beverage, and wellness DTC brands, where category-specific retention curves and creative format knowledge matter.

Headquarters: Marina del Rey, CA

Year Founded: 2018

Team Size: 20–50

Key Services:

• Paid Social (Meta, TikTok, Google)
• Email and SMS Lifecycle Marketing
• Performance Creative (In-House)

Why Choose Structured Agency:

The integrated lifecycle layer is the differentiator. Email and SMS running in concert with paid acquisition is exactly the structure that compounds LTV, and many brands discover too late that splitting those across vendors quietly caps growth. Category depth in beauty, fashion, food and beverage, and wellness DTC means the team has seen the specific retention curves those products produce. If you are weighing a move from a current partner, our guide to the 7 questions to ask before switching media agencies is a useful gut check before you commit.

• Beauty and Personal Care
• Fashion and Apparel
• Food and Beverage
• Health and Wellness DTC

8. Darkroom

Darkroom is an AI-native DTC growth agency founded in 2017, offering integrated paid media, Amazon, TikTok Shop, performance creative, retention, and conversion rate optimization under one roof. The agency operates across a distributed team and leans on AI across bidding automation, creative testing, audience modeling, and reporting rather than retrofitting legacy workflows. It manages significant ad spend for consumer brands across beauty, wellness, CPG, and food and beverage.

Headquarters: Los Angeles, CA

Year Founded: 2017

Team Size: 50–200

Key Services:

• Paid Media (Meta, Google, TikTok Shop, Amazon)
• Amazon and TikTok Shop Management
• Retention and CRO
• Performance Creative and AI-Driven Testing

Why Choose Darkroom:

Darkroom's pitch is integration: paid, marketplace, creative, retention, and CRO under one roof with an AI-native approach to how the work gets done. For a DTC brand selling across its own store, Amazon, and TikTok Shop at once, that single-operator coverage removes a lot of vendor coordination. The breadth means the right diligence question is depth: confirm the marketplace and retention teams are as strong as the paid one, not just attached to it. For brands that want one partner across the full DTC and marketplace surface, the model is coherent.

Industries:

• Beauty and Wellness
• Consumer Packaged Goods
• Food and Beverage
• Direct-to-Consumer Marketplace Brands

9. Power Digital

Power Digital is a data-science-led agency headquartered in San Diego, with paid media across Meta, Google, Amazon, and retail media, retention, and a proprietary modeling platform (nova) that connects spend to revenue outcomes. The agency was founded in 2012 and has grown to over 500 employees, serving mid-market to larger consumer brands across ecommerce, health and wellness, and lifestyle categories. For ecommerce brands, the relevant challenge it addresses is attribution fragmentation across own-store, Amazon, and retail media revenue.

Headquarters: San Diego, CA

Year Founded: 2012

Team Size: 500+

Key Services:

• Paid Media (Meta, Google, Amazon, Retail Media)
• Data Science and nova Platform Analytics
• SEO and Content Marketing
• Retention and Lifecycle Marketing

Why Choose Power Digital:

For an ecommerce brand, the case for Power Digital is its modeling capability applied to DTC contribution-margin growth rather than channel reporting, which is increasingly necessary as marketplace and retail-media revenue blurs the picture across own-store and Amazon. The analytics depth helps brands that need retention and acquisition planned against one revenue model rather than two disconnected dashboards. The diligence question worth asking before signing is whether the engagement is genuinely modeling-led for your DTC P&L or whether it operates as a standardized channel-management package with analytics presented separately. Brands evaluating media-buying capability specifically can also see our best media buying agencies comparison for a complementary view.

Choosing the right ecommerce marketing agency

The right ecommerce agency depends less on which name ranks first and more on whether the shop's specialization matches the growth question your business is actually trying to answer. A growth-stage Shopify brand fighting CAC inflation has a different problem than a mid-market brand whose growth now hinges on LTV expansion, which is different again from a brand where Amazon and TikTok Shop have become a meaningful share of revenue. Match the agency to that question, not to a list position.

Each agency here has a real specialization. Common Thread Collective brings a forecasting model. Pilothouse and MuteSix bring in-house buying and creative depth. Brighter Click and Structured Agency bring focused growth-stage and lifecycle work. Black Propeller leads with paid search. Darkroom integrates marketplace and AI-native operations. Power Digital brings analytics modeling. And QRY is built for the brands that need paid growth measured on contribution profit and incrementality, with senior practitioners owning the relationship directly. Before you commit to any of them, ask how they isolate incremental contribution from baseline demand, what proof they can show from a holdout or lift study, and whether their measurement approach would survive a channel going dark for a month. That discipline separates agencies accountable to your P&L from ones accountable to their own dashboards.

If you are mid-evaluation, the diligence questions that matter are not the ones most agency websites prepare you for. Our guide on how to choose a paid media agency walks through the proof points to demand and the red flags worth taking seriously before you sign.
