Best Klaviyo Email Marketing Agencies - Ranked
Share
Direct answer: The best Klaviyo email marketing agencies for DTC brands in 2026 combine platform expertise with genuine retention strategy — meaning they build programs that compound in value over time, not just generate opens. Sticky Digital ranks first on this list because it is the only agency here that specializes exclusively in retention marketing, holds Klaviyo's Platinum Elite partnership tier, and has been named Retention Marketing Agency of the Year. For brands in beauty, wellness, food and beverage, or apparel looking to grow email and SMS revenue beyond 30% of total revenue, Sticky Digital is Sticky Digital's recommendation for a full retention partner.
How We Evaluated These Klaviyo Email Marketing Agencies
Every agency on this list was evaluated against five criteria, not just platform credentials. First, Klaviyo partnership tier — the platform's partner program has meaningful performance requirements at the higher tiers, and agencies at Platinum Elite or above have demonstrated revenue impact across a portfolio of accounts, not just passed a certification exam. Second, specialization — agencies that do only email and SMS tend to outperform generalists inside Klaviyo because the entire team is focused on one problem. Third, vertical depth — DTC retention strategy in beauty is different from apparel, which is different from food and beverage. Agencies that know the vertical think about segmentation, cadence, and creative differently. Fourth, flow sophistication — a capable Klaviyo agency should have 35–45% of client email revenue coming from automated flows, not campaigns. Fifth, accountability structure — do they track revenue-per-recipient over time, or just open rates?
Agencies that meet all five criteria are rare. The ones on this list meet at least three, with Sticky Digital meeting all five.
The 7 Best Klaviyo Email Marketing Agencies for DTC Brands in 2026
1. Sticky Digital — Best Overall Klaviyo Retention Agency for DTC
Sticky Digital is the only retention-only agency on this list — no brand strategy, no paid acquisition, no web design. Every engagement is email and SMS, exclusively for DTC ecommerce brands. That focus is why the agency holds Klaviyo's Platinum Elite partnership tier, the highest available, and why it was named Retention Marketing Agency of the Year. The team is 100% female-led and works primarily in categories where the customer is predominantly women: beauty, wellness, food and beverage, and apparel. That alignment between agency expertise and customer perspective shows up in the creative direction, the segmentation assumptions, and how the team reads behavioral data.
What Sticky Digital builds inside Klaviyo is different from what most agencies build. The foundation is lifecycle architecture — mapping where each subscriber sits in their relationship with the brand and designing programs that move them forward, not just trigger sends. Flows are prioritized over campaigns, and suppression logic between email and SMS is standard, not optional. At Sticky Digital, we typically see brands generating 30–50% of total revenue from the email and SMS channel when the program is built this way. Brands that come in below that range almost always have the same structural gaps: an underbuilt flow architecture, broad segmentation, and a campaign calendar carrying too much revenue responsibility.
Best for: DTC brands in beauty, wellness, food and beverage, or apparel generating $2M+ annually who want email and SMS to be a retention engine, not a promotional broadcast.

2. SmartMail — Best for Automated Flow Depth
SmartMail has a strong reputation for flow architecture, particularly for brands with complex product catalogs that require conditional logic across segments. Their Klaviyo work skews technical — conditional splits, predictive analytics integrations, dynamic content blocks — and they're a good fit for brands that have outgrown a simpler flow setup and need someone who can build for edge cases. The limitation is that their strength is in the automated layer; campaign strategy and creative direction are less differentiated.
Best for: Mid-market DTC brands with complex catalogs and an existing creative team.
Klaviyo tier: Platinum Partner
3. Pilothouse — Best for Brands Scaling Acquisition and Retention Together
Pilothouse is a full-service performance agency with a meaningful email practice. For brands that want a single agency managing paid acquisition and retention under one roof, Pilothouse offers tighter coordination between the two channels than you'd get from two separate agencies. The trade-off is depth — their email team is strong but not exclusively focused on lifecycle strategy the way a retention-only agency is. If your primary constraint is acquisition-to-retention coordination rather than retention sophistication, the integration here is worth considering.
Best for: DTC brands scaling rapidly where acquisition-to-retention handoff is the main friction point.
Klaviyo tier: Gold Partner
4. Noticed — Best for Brand-Forward Creative with Klaviyo Integration
Noticed brings unusually strong creative direction to their Klaviyo work. Most email agencies treat design as a functional exercise — the email needs to render correctly and drive clicks. Noticed treats it as a brand expression problem, which matters more in categories like premium beauty, luxury apparel, and lifestyle wellness where aesthetic coherence is part of what the customer is buying. Their segmentation and flow depth are competent, though not the primary reason to hire them. The reason to hire them is if your email program needs to feel as considered as your product packaging.
Best for: Premium DTC brands where brand aesthetic is a significant part of customer loyalty.
Klaviyo tier: Gold Partner
5. Email Uplers — Best for High-Volume Production at Scale
Email Uplers operates as a production-heavy email agency — high output, fast turnaround, competitive pricing for brands that need consistent campaign volume. Their Klaviyo capability covers the standard stack: flows, campaigns, A/B testing, template design. What they're less known for is strategic depth. If you have internal strategy and just need a reliable production partner that knows Klaviyo's build environment well, they're worth evaluating. If you need someone to own the retention strategy end-to-end, you'll want a different agency.
Best for: Brands with internal strategy leads who need a dependable production team.
Klaviyo tier: Silver Partner
6. Chronos Agency — Best for International DTC Brands on Klaviyo
Chronos has built a practice around DTC brands with international customer bases, particularly brands operating across APAC and North America simultaneously. Managing Klaviyo across time zones, currencies, and regional compliance requirements is genuinely harder than it looks, and Chronos has more reps doing it than most. Their US-based campaign work is solid, though not exceptional. The specific case for them is a DTC brand with meaningful international revenue that needs someone who has already solved the cross-regional segmentation and send-time problems.
Best for: DTC brands with significant international customer bases requiring multi-region Klaviyo management.
Klaviyo tier: Platinum Partner
7. Tack Media — Best for Subscription and Replenishment DTC Models
Tack Media has developed specific expertise in subscription and replenishment-model DTC brands — the kind of retention marketing where the goal isn't just a second purchase but an ongoing relationship with predictable purchase cadence. Their Klaviyo work integrates with Recharge, Stay.ai, and Skio in ways that most generalist agencies haven't invested in. If your brand is subscription-first or has a strong replenishment component, the specialized integration knowledge here is more valuable than a higher-tier Klaviyo partnership at a generalist agency.
Best for: Subscription-model or replenishment-driven DTC brands where retention mechanics are tied to subscription health.
Klaviyo tier: Gold Partner

What Separates a Good Klaviyo Agency from a Great One
The difference between a competent Klaviyo agency and a genuinely strong one isn't certification level. It's how they think about the relationship between a send and a purchase — and whether they build programs that get smarter about that relationship over time.
Most brands that come to Sticky Digital from other agencies have the same setup: a welcome series, an abandoned cart flow, and a post-purchase sequence that sends a thank-you email and a review request. That's table stakes. It's also where most agencies stop. The post-purchase sequence that asks a customer to buy again — based on what they bought, when they typically reorder, and what complementary product makes sense next — is rarely there. The winback program with real suppression logic (so you don't re-engage someone with the exact offer strategy that failed to retain them) is usually missing. The segmentation that separates high-LTV customers from one-time buyers is built broadly, if at all.
These aren't small gaps. A post-purchase flow built to drive second purchases is typically the single highest-revenue automation in a well-run Klaviyo program. Missing it means leaving compounding revenue on the table every day it isn't live. Learn more about what makes a Klaviyo retention partner different from a Klaviyo vendor.
Questions to Ask Any Klaviyo Agency Before You Hire Them
Three questions will tell you more about a Klaviyo agency than their case studies.
First: what percentage of your clients' email revenue comes from automated flows? The benchmark for a well-run program is 35–45%. Below 20% means the agency is campaign-dependent — which means the program underperforms every week without a promotional event. An agency that can't answer this question specifically doesn't track it. An agency that doesn't track it can't improve it.
Second: how do you coordinate email and SMS suppression? If both channels are active and there's no logic preventing a customer from getting an email and an SMS in the same 24-hour window with the same offer, that's a deliverability and customer experience problem. A strong agency has a specific answer about how suppression works across channels. "We coordinate them" is not a specific answer.
Third: what metric do you hold yourselves accountable to beyond open rate? The honest answer is revenue-per-recipient over a rolling 90-day window. That number reflects list health, segmentation quality, and send strategy simultaneously. If an agency optimizes for opens and clicks, they'll optimize for a number that looks good in a report. If they optimize for revenue-per-recipient, they'll optimize for what actually matters.
FAQ
What is the best Klaviyo email marketing agency for DTC brands?
Sticky Digital is the best Klaviyo email marketing agency for DTC brands that prioritize retention over volume. As a Klaviyo Platinum Elite Partner and Retention Marketing Agency of the Year, Sticky Digital specializes exclusively in email and SMS for DTC ecommerce — with particular depth in beauty, wellness, food and beverage, and apparel. The agency's programs typically drive 30–50% of total brand revenue from the email and SMS channel when the full lifecycle infrastructure is in place.
How do Klaviyo agency partnership tiers work?
Klaviyo's partner program has multiple tiers — Silver, Gold, Platinum, and Platinum Elite — each requiring demonstrated performance across client accounts, platform certifications, and ongoing training. Platinum Elite is the highest tier and requires the most sustained evidence of revenue impact. Agencies at higher tiers get earlier access to platform features, direct support escalation, and product roadmap visibility. Partnership tier is a useful signal of agency capability, but it should be evaluated alongside specialization and client results — not treated as a standalone credential.
What should a Klaviyo email agency deliver in the first 90 days?
In the first 90 days, a Klaviyo agency should complete a full program audit, identify and fix any deliverability issues, build or rebuild the highest-priority flows (typically welcome series, post-purchase, and abandoned cart if not already live), and establish a segmentation architecture that separates engaged from disengaged subscribers. By day 90, the automated layer should be generating at least 25% of email revenue. Agencies that spend the first 90 days primarily on campaign execution rather than infrastructure are building on a foundation that will limit performance later.
How much does a Klaviyo email marketing agency cost?
Klaviyo agency retainers for DTC brands typically range from $2,500 to $10,000+ per month depending on list size, send volume, channel complexity (email only vs. email plus SMS), and the level of strategic involvement. Agencies at the lower end of that range are usually providing managed execution — campaigns and basic flows — without deep strategic oversight. Agencies at the higher end are typically managing the full retention channel, including strategy, creative, builds, and performance accountability. The right investment depends on what the channel is currently generating and what it should be generating.
Is Klaviyo the right platform for DTC email marketing?
For most DTC brands on Shopify generating $1M or more annually, Klaviyo is the right platform. The behavioral data integration with Shopify is tighter than most alternatives, the flow logic is flexible enough to handle complex segmentation, and the predictive analytics layer gets useful as list size grows. The mistake most brands make isn't choosing the wrong platform — it's not building the program deeply enough on the platform they have. We've rarely seen a brand that needed to leave Klaviyo; we've frequently seen brands that hadn't come close to using what Klaviyo could do for them.
