Klaviyo Marketing Agencies (5)

START WITH THE BRIEF

What kind of Klaviyo marketing help do you need?

Klaviyo can support a better relationship after the first visit or purchase. Decide whether the priority is the customer journey, email and SMS creative, data quality, or the store that feeds the program.

Ask which flows the agency would build, how segments and consent work, and what repeat-purchase result the team would watch.

THE DIRECTORY, WITH CONTEXT

A closer look at each agency

Each profile below explains the agency's broader specialty, where it may fit, and what to ask before hiring.

Cake Commerce

Specializes in ecommerce consulting, design, email, influencers, loyalty, and reporting

Consider for: A retail brand with an operating store and customer data that wants acquisition and repeat purchase measured as one commercial journey.

Why included: Identifies itself as a Klaviyo partner for ecommerce email and SMS. See the agency example ↗

Before hiring: Worth exploring when acquisition and repeat purchase need one plan. Ask for the proposed channel mix, reporting ownership, and the costs of any loyalty or dashboard tools.

Blue Wheel Media

Specializes in retail media, marketplaces, direct-to-consumer growth, social commerce, and lifecycle marketing

Consider for: A beauty or consumer brand selling through retailers, marketplaces, and its own store that needs a shared plan and product-level reporting across those channels.

Why included: Documents a client email program with automated flows in Klaviyo. See the agency example ↗

Before hiring: A useful comparison when a beauty brand sells through retailers, marketplaces, and its own store. Ask how the team separates new demand from sales that shift between channels.

Blue Water Marketing

Specializes in SEO, email, social, display, retargeting, and design

Consider for: A business with existing campaigns but uncertain returns, prepared to share channel access and choose a few tests before expanding the mix.

Why included: SEO, email, social, display, and retargeting give the team several levers, making an audit and channel priorities important before execution. Visit the agency website ↗

Before hiring: Consider it if your acquisition channels need coordinated testing. Ask what the initial audit covers, which channels the team would prioritize, and how spend will be reported.

Avex

Specializes in Shopify design and commerce architecture with lifecycle services such as email and SMS

Consider for: An established commerce team with a complex catalog, integration, or customer journey and the resources to maintain substantial custom work.

Why included: Shopify design, commerce architecture, and lifecycle work can be scoped together when the storefront itself is a growth constraint. Visit the agency website ↗

Before hiring: Consider it for a demanding commerce build with the budget and internal team to maintain custom work. Compare a simpler native-theme approach and ask what long-term ownership will cost.

Happy Shark Media

Specializes in social media, web design, SEO, email, and photography together

Consider for: A visual consumer brand short on both creative assets and distribution capacity, with a clear audience and approval process for recurring content.

Why included: Photography and visual production sit beside social, web, search, and email, connecting content assets with the places they will be used. Visit the agency website ↗

Before hiring: Worth exploring when your content library and channels need attention at the same time. Ask who produces the creative, who runs the campaigns, and what ongoing output is included.

BEFORE YOU CHOOSE

Questions worth taking to a first conversation

Relevant work: Ask for a recent project that resembles your brief and learn what the agency actually delivered.
The proposed team: Meet the people who would do the work and ask what they would focus on first.
Scope and results: Ask which flows they will build, how consent is managed, and how results are measured.
Costs: Clarify fees, outside production or software costs, and what happens after launch.
