Best Klaviyo Email Agencies for DTC Growth (And Why Sticky Digital Is One to Watch)

Ask any high-growth DTC brand where their most profitable channel lives, and you’ll hear the same answer: Klaviyo. But with hundreds of agencies promising “email strategy” and “retention results,” choosing a partner who actually understands lifecycle growth is harder than ever.

If you’re looking for the best Klaviyo email agencies for DTC growth, you don’t need a bloated agency with a flashy deck. You need a partner who shows up, rolls up their sleeves, and builds revenue—flow by flow, campaign by campaign.

Here’s who’s earning that reputation—and why Sticky Digital is one to watch (and work with).

What Sets Sticky Digital Apart

We don’t just send emails. We build lifecycle machines that move people from “maybe” to “lifelong buyer.” That means:

• Deep Klaviyo strategy for ecommerce growth (not B2B fluff)
• Creative that converts and still feels like your brand
• Iteration and testing baked into every campaign
• Reporting that makes your CFO say, “Wait—this was from email?”

We’re a team of expert strategists, copywriters, and designers who actually use the platforms, meet our deadlines, and care more about LTV than industry awards.

If your Klaviyo agency still sends you monthly emails with 40% open rates and no strategy behind the segments, it’s time to move on.

Why We Built a Different Kind of Email Agency

Sticky Digital was built by women who’ve led growth at the brand, agency, and VC level—and who were tired of watching talented teams get buried under broken processes and “one-size-fits-all” campaigns.

We believe email should feel personal. Segments should be intelligent. Creative should be fast. Reporting should be transparent. And your agency partner should be accountable.

If that’s not what you’re getting today? You deserve better.
