The Best Ecommerce Marketing Agencies

Updated September 6, 2026 · 7 agencies · How we build these lists

The short answer

The right ecommerce marketing agency depends on which constraint is actually limiting growth. Pilothouse fits brands adding channels without adding agencies. inBeat fits brands short on creative volume. Stryde fits brands whose customers search the category by name. The Social Shepherd fits social-first and TikTok Shop brands. Darkroom fits brands selling across DTC, Amazon, and retail at once. Sweat Pants Agency fits brands whose constraint is paid acquisition cost. Avenue Z fits brands prioritizing AI search visibility and earned media.

Before comparing proposals, work out whether your primary constraint is acquisition cost, conversion, creative output, organic visibility, or repeat purchasing. Agencies are not interchangeable across those problems, and the most common hiring mistake is buying media management when the actual bottleneck is that you cannot produce enough creative to keep an account learning. Give every finalist the same brief and compare their first 90 day priorities.

Agency profiles

Pilothouse

Best for brands adding channels without adding agencies

Victoria, BC

Pilothouse runs Amazon, Google, Meta, TikTok, YouTube, email, SMS, and CRO through channel-specific in-house teams, with 500 or more DTC brands served and $1B+ in attributable revenue reported. The fit when the constraint is coordination across channels rather than depth in one.

inBeat

Best for brands whose constraint is creative volume

Montreal, Canada

inBeat produces UGC and creator content at volume through a nano to macro creator network, and runs paid across Meta, TikTok, Snapchat, and Google. Named work includes Dr Squatch, HelloFresh, New Balance, and Native. The right call when you cannot produce enough distinct concepts to keep an ad account learning.

Worth knowing: Less relevant if you already have creative supply and need better media buying.

Stryde

Best for brands whose customers search for the category by name

Stryde works only in search: ecommerce SEO, Google Ads, and AI search optimization, deliberately excluding paid social. It states a $1M to $15M revenue band, which is narrower and more specific than most agencies publish. Named work includes Ergobaby, Goal Zero, and Nomatic.

Worth knowing: A poor fit for brands in categories where demand has to be created rather than captured.

The Social Shepherd

Best for social-first brands and TikTok Shop

Bath and London, UK, with New York and Miami

The Social Shepherd runs organic social, creative production, and paid social as a single practice rather than separate departments, with a more developed TikTok Shop offering than most. Named work includes UNIQLO, ASICS, BARK, and Lavazza, and it has been named Best Large Social Agency three years running.

Darkroom

Best for brands selling across DTC, Amazon, and retail at the same time

New York, NY

Darkroom is built for the allocation question that appears once a brand sells in several places at once, and runs an in-house modeling platform aimed at it. Named work includes Olipop, Everlane, and Anne Klein.

Sweat Pants Agency

Best for brands whose constraint is paid acquisition cost

Nashville, TN

Sweat Pants Agency is built around high-volume creative testing on Meta and Google for DTC and subscription brands, reporting over $350M in managed spend and Meta Premium Partner status. Its case studies concentrate on categories where repeat purchase carries the economics, including Hunt A Killer, Kitty Poo Club, and Tearribles.

Avenue Z

Best for brands that want to be visible in AI search and earned media

New York, Miami, and Orlando

Avenue Z combines PR with AI search optimization on the thesis that being cited by language models follows from being written about. For brands that care whether ChatGPT or Perplexity names them in a category answer, that pairing is the relevant offer. Named work includes Dave, Better, and Cocokind.

Frequently asked questions

How much does an ecommerce marketing agency cost?
Retainers commonly start around $3,000 to $6,000 per month for a single channel and rise with scope and spend. Many agencies price as the greater of a base retainer or a percentage of ad spend, typically 5 to 15 percent. Creative production is the largest variable and is frequently scoped separately, so ask for it to be quoted explicitly.
How do I know which constraint is limiting my growth?
If CPAs are rising while conversion rate holds steady, the constraint is usually creative or audience saturation. If traffic is healthy but conversion is low, it is the site or the offer. If both are fine but revenue is flat, it is repeat purchase. If you are invisible for category searches, it is organic visibility. Diagnose this before you brief agencies, because each one will tend to see the constraint their service happens to solve.
Should I hire one full-service agency or several specialists?
Specialists usually go deeper per channel; a single agency reduces coordination cost and makes cross-channel measurement coherent. The practical threshold is internal capacity. If nobody on your team has time to arbitrate between three agencies making competing claims on the same revenue, consolidate.
What should I ask every agency on the shortlist?
Give all of them the same brief and ask for their first 90 day priorities, the named people who will do the work and how many other accounts those people carry, the measurement plan including which metric they manage to, and two references from brands in a similar revenue band and business model. The differences in those four answers are usually more revealing than the pitch decks.
