The 10 Best Klaviyo Agencies for DTC Brands (2026)

The YOCTO editorial team is in-house lifecycle strategists, email and SMS specialists, and Klaviyo-certified operators behind every article on this site. YOCTO’s client work has been published by Klaviyo, Skio and Loop under their own names, and its retention methodology - the LTV Parthenon - is published in Forbes. Klaviyo Elite Master, 2025-2026.

We looked up every agency on this list in Klaviyo’s own partner directory on 23 September 2026 and wrote down the tier it actually holds. Ten cleared. One of them advertises a higher tier on its own website than the directory gives it, which is the short version of why this page exists: the badge in a footer is a marketing decision, and the badge in the directory is a fact.

Key Takeaways

  • Partner tier is checkable in ninety seconds in Klaviyo’s own partner directory, and it is the single fastest way to test whether an agency describes itself accurately. Every tier below was read there on 23 September 2026.
  • One agency here claims a higher tier on its own site than the directory shows. We have listed the directory tier, because that is the method. We are not naming it, because tiers get re-reviewed and a site can simply be out of date. Check the ones you shortlist.
  • One of the ten publishes results by category rather than by brand - an “automotive case study” rather than a named client. A number with no brand on it cannot be checked by you or by anyone else.
  • “DTC” is not a specialism. Almost every Klaviyo agency serves DTC brands, so the word filters nothing. What filters is whether lifecycle is the whole business or one service among ten.
  • Every agency here is a lifecycle specialist, and that is the filter. The large full-service shops that also sell paid media and development are deliberately absent, including several that appear on competing lists. If you want one agency for everything, this is the wrong list and we say so below.
  • Several agencies on the biggest competing list returned no directory profile we could find. More on that below, with the caveat it deserves.
  • Retention compounds and acquisition does not. A DTC brand that fixes repeat purchase changes the maths on every future acquisition pound. That is why this category is worth getting right.
The fast answer

Start Here, by Situation

Most people arriving on a page like this do not want ten profiles. They want the one page that matches their situation. Here is where to go.

How We Judged These Agencies

Three criteria. All three are things you can check yourself in an afternoon, which is the point.

  1. Verified partner tier. Read from Klaviyo’s own partner directory on 23 September 2026, not from the agency’s own site. Where the two disagree, we published the directory.
  2. Lifecycle as a core offer. Retention, email and SMS have to be what the agency sells, in its own words on its own site. Agencies where email is one line item under paid media and web development are not on this list.
  3. A published client result. A case study you can open, with a number. Where the brand is named we say so; where results are published by category instead, we say that too, because it is a meaningful difference.

We did not score anyone out of ten. Every cell below is a factual state, not an opinion dressed up as data.

Tiers were read on 23 September 2026. YOCTO wrote this list and is on it, judged by the same three criteria.

One column is worth reading twice. Several agencies here do retention; one row covers lifecycle, retention and subscription as a single practice, and that is ours. It is not a claim about effort, it is a claim about evidence: the only result on this page published by a subscription platform is ours, where Skio wrote up a 48% cut in cancellations and a 208% lift in reactivations for Gratsi. Cancellation, dunning and reactivation are where recurring-revenue businesses actually leak, and they are a different discipline from campaign performance.

If you want the tier question on its own - what Elite Master actually means, how many hold it, and whether you need one - that is a separate page: the best Klaviyo Elite Master agencies. This list is about who does lifecycle as the business, at any tier.

The agencies

YOCTO

Klaviyo Elite Master, 2025-2026. YOCTO LTD is based in Nicosia, Cyprus, and works with DTC and subscription brands roughly in the five to one hundred and fifty million range, across supplements, beauty and skincare, and femtech.

The argument for YOCTO in DTC is that we only do the one thing. There is no paid media team whose budget competes with yours, and no development roadmap that pushes a flow rebuild to next quarter. What we build is the repeat-purchase engine: product-level replenishment timing, segmentation that uses the order data properly rather than a handful of tags, winbacks that distinguish a lapsed subscriber from a one-time discount buyer, and the cancellation and reactivation paths that decide what a subscription is actually worth.

Six published results. The first three are our own write-ups. The last three were published by Klaviyo and Skio under their own names rather than ours, which is the harder kind to get and exactly what this page asks of everyone else.

Best for

DTC and subscription brands where repeat purchase is the constraint, the catalogue has outgrown its flows, and nobody owns the lifecycle properly.

Not for

Brands that need paid media, a store rebuild or a full-funnel team. We do lifecycle, and so does everyone else on this list. That is deliberate, and it means a brand that wants one agency for everything should be looking at a different kind of list altogether.

Flowium

Klaviyo Elite Master, and one of the few agencies here whose homepage title is simply a retention marketing agency for ecommerce. Lifecycle is the entire offer, and the site is built around flows, campaigns and the arithmetic of repeat revenue rather than a services grid.

Their published work is a mix. The case-study tiles on the homepage are labelled by category rather than by brand, which tells you nothing you can verify, but the full case-study library does name brands: The Sports Edit at 28% year-on-year growth through Black Friday, and Alen in the same set. If you read one thing before a call, read the named ones.

Best for

Ecommerce brands that want retention as the whole engagement and are comfortable with a mid-sized, lifecycle-only team.

Not for

Buyers who need every case study to carry a brand name before they will shortlist.

Chronos Agency

Klaviyo Elite Master, positioned explicitly as a retention and lifecycle marketing agency for DTC brands, and the largest operation on this list by volume of accounts: they cite more than 500 brands and publish a system built around email, SMS and push together rather than email alone.

That scale is the argument and the caveat in one. A 500-brand playbook means the patterns are tested and the team has seen your category before. It also means you are one account among many, and the named senior operator you meet in the pitch is not necessarily the person in your account on a Tuesday. Their success stories publish strong figures, but the ones on the index are grouped by category rather than by brand.

Best for

Brands that want a proven playbook, push notifications included, and are comfortable with a large agency.

Not for

Brands that want a small senior team and a named lead who stays on the account.

Magnet Monster

Platinum Master in the directory, and the clearest focus on churn among the agencies here. Their published work leans into retention and churn together, which in practice means cancellation flows and the repurchase mechanics that a straight email agency often leaves alone.

They publish named client results, which puts them in the smaller half of this list: Carved at a 200% increase in email revenue with a click-rate lift alongside it, and French Florist at a 20% revenue increase achieved while halving the attribution window, which is a more honest way to report a number than most.

Best for

DTC brands where churn, not acquisition, is the constraint.

Not for

Brands wanting an Elite-tier bench for a complex multi-region account.

Andzen

Klaviyo Elite Master, based in Australia, positioned as retention and CRM for ecommerce with Klaviyo at the centre rather than as one integration among many. They are the strongest option here for brands operating in Asia-Pacific time zones, which matters more than it sounds when a Black Friday send needs a decision at 6am your time.

They publish named results, including Rose-Hip Vital growing revenue 25% in the month after migrating to Klaviyo, and client work with Hard Yakka. Migration is a visible strength; if you are moving onto Klaviyo rather than optimising an account that is already there, they are worth a call.

Best for

Brands in Australia and Asia-Pacific, and anyone migrating onto Klaviyo rather than tuning an existing account.

Not for

Brands wanting local hours and local deliverability knowledge in North America or Europe.

Get Better

Klaviyo Elite Master, based in the UK, positioned as CRM and email marketing specialists. They publish more case studies than almost anyone here, which is the quiet signal worth paying attention to: a library of named clients is harder to fake than a headline.

Published figures include PerfectTed at 312% revenue growth year on year across campaigns and flows, MOMA Foods, and a 245% revenue increase in flow automations. The range of named brands across food, drink and consumer goods suggests a team comfortable outside a single vertical.

Best for

UK and European brands wanting a CRM specialist with a deep, checkable client library.

Not for

Brands whose core problem is recurring-revenue churn rather than campaign and flow performance.

Hustler Marketing

Klaviyo Elite Master, and by their own description a full-service email marketing agency. The emphasis is execution volume: a large team producing a high cadence of campaigns and flows, with a case-study library covering tools, supplements and niche retail.

Full-service in their sense means email and SMS end to end rather than email plus paid media, so this is still a lifecycle agency. The trade-off is style: if you want a strategist to challenge your offer and your retention programme before writing a single email, look at the retention-first agencies above. If you want throughput and a team that will simply ship, this is the profile.

Best for

Brands that need volume and consistency of output across email and SMS.

Not for

Brands whose problem is strategy and pricing rather than production capacity.

Underground Ecom

Klaviyo Elite Master, focused on email for fast-growing ecommerce brands. We know their work well enough to have written about it separately, and the positioning is genuinely lifecycle-first rather than a services menu.

The gap, stated plainly because we apply the same rule to ourselves, is that we could not find a published client result with a figure on their site. That does not mean the work is not there. It does mean the fastest check available to you comes back empty, and you are relying on references instead.

Best for

Fast-growing brands scaling email who are happy to diligence by reference and account walkthrough.

Not for

Procurement processes that require published, checkable client outcomes.

Essence of Email

Gold Master, and the most explicitly boutique agency here: a small email and SMS team selling senior attention rather than scale. For a brand that has been passed to a junior account manager at a larger agency, that is the entire pitch and it is a good one.

They publish named results, including Oransi at a 9,245% revenue increase with Klaviyo and email strategy. A number that large is a function of a very low starting base rather than a repeatable benchmark, and it is worth reading the case study to understand what moved rather than anchoring on the headline.

Best for

Smaller brands that want senior operators on the account rather than an account team.

Not for

Brands needing a large bench, multi-region coverage or an Elite-tier requirement.

Mailody

Klaviyo Elite Master, based in Germany and operating in German. For a DACH brand, working in your own language with an agency that understands local consent norms and the way German consumers respond to email frequency is worth more than a marginally better case study from an English-speaking team.

The same gap applies as to two others on this list: we could not find a published client result with a figure. Elite Master is a meaningful credential and a strong starting point, but the proof is a conversation rather than a link.

Best for

German-speaking brands in the DACH market wanting Elite-tier Klaviyo work locally.

Not for

Brands outside German-speaking markets, or buyers who need published outcomes.

Narrowing it down

Why There Is No Full-Service Agency on This List

Criterion two did most of the work on this page, and it is worth being explicit about what it removed. Several well-known Klaviyo partners hold a perfectly good tier and were left off because lifecycle is one service among ten on their own site: one is a growth agency weighted to paid media, one is a store-development shop with lifecycle attached, one leads with acquisition, and two are enterprise media agencies. None of that makes them bad. It makes them a different purchase.

So the fit question inside this list is not specialist versus full service. Every one of the ten is a specialist. The question is which kind: lifecycle only, lifecycle plus CRM breadth, or production volume across email and SMS.

Agency Engagement shape Best-fit stage
YOCTO Lifecycle, retention and subscription DTC and recurring-revenue brands where repeat purchase is the constraint
Flowium Lifecycle only Brands wanting retention as the whole engagement
Chronos Agency Lifecycle only, large bench Brands wanting scale and a 500-brand playbook
Magnet Monster Lifecycle and churn DTC brands where churn is the main number
Andzen Lifecycle and CRM Brands in APAC wanting platform depth
Get Better Lifecycle and CRM UK brands wanting a CRM specialist
Hustler Marketing Full-service email and SMS Brands wanting execution volume
Underground Ecom Lifecycle only Fast-growing brands scaling email
Essence of Email Boutique email and SMS Smaller brands wanting senior hands
Mailody Lifecycle only German-speaking brands in the DACH market

Read that against your actual constraint. If the store converts and the problem is that customers do not come back, any of these will go deeper than a full-service agency would, for less money. If you are replatforming or rebuilding in the same quarter, none of them will do that for you, and splitting the work across two agencies creates a seam exactly where your customer data lives. That is a real cost, and it is the one reason to consider a wider agency instead of anyone on this page.

The check nobody publishes

Why Most DTC Agency Claims Do Not Survive a Check

“DTC” is the least useful filter in this category. Klaviyo is a DTC ecommerce platform, so every agency in the ecosystem serves DTC brands by definition. Searching the directory for it returns most of the directory. The word tells you nothing and appears on every site, which is exactly why it is on every site.

Three checks do work, and all three take minutes.

Read the tier in the directory, not the footer. One agency on this list advertises a higher tier on its own website than the directory records. We have published the directory tier and we are not naming them, for a reason worth stating: Klaviyo re-reviews tiers periodically, and a site that is six months out of date is careless rather than dishonest. But it demonstrates the point. A badge you cannot verify is decoration.

Check whether the result has a brand on it. Two agencies here publish figures attributed to “an automotive brand” or “cycling and triathlon equipment”. Those numbers may be entirely real. They are also unfalsifiable, and a claim nobody can check is worth less than a smaller claim that anyone can. Ask for the brand name on the call and see what happens.

Check they are in the directory at all. The largest competing list of Klaviyo agencies for DTC brands includes at least three names for which we could not find a directory profile after searching by several plausible identifiers. We are stating that carefully, because a failed lookup is not proof of absence and the directory search is unreliable for name matching. But if the single fastest credential check available to a buyer returns nothing, that is worth knowing before a call rather than after a contract.

What to watch for

Red Flags When Evaluating a Klaviyo Agency

These come up repeatedly in audits of accounts that were previously agency-managed.

  • The pitch opens with templates. If the first slide is design, the agency is selling production. Your first month should be spent on deliverability, list health and what data is actually reaching Klaviyo from your store.
  • Revenue claims with no attribution window. “We grew email revenue 300%” means nothing without knowing the window and the model. An agency that volunteers its attribution settings before you ask is telling you something good about itself.
  • Flow counts as a deliverable. Forty flows is not better than twelve. It is usually worse, because the overlap creates suppression problems nobody is tracking.
  • No mention of suppression or sunsetting. An agency that only talks about sending is going to burn your list and then explain the drop in deliverability as an inbox-provider change.
  • A single named strategist in the pitch who does not appear again. Ask directly who is in the account weekly, and ask to meet them.
  • No opinion about your offer or your subscription programme. In DTC the email is rarely the constraint. An agency with no view on pricing, bundles or cadence is going to optimise around a problem it cannot fix.
What happens next

What the First 90 Days Should Look Like

Whoever you pick, the shape of a competent DTC lifecycle engagement is consistent, and knowing it is the easiest way to tell during a pitch whether the agency has done this before.

Weeks one to three: audit and data. Deliverability, list health, and a real look at what product, order and subscription data is reaching Klaviyo from the store. This is where most problems are actually found.

Weeks two to six: the flows that pay for the engagement. Welcome, abandoned browse and cart, post-purchase, and a first pass at replenishment or subscription lifecycle depending on your model.

Weeks four to ten: segmentation and suppression. Engagement tiers, sunset rules, and the segments that make recommendations land. The least visible work and the most durable.

Weeks eight to twelve: campaigns on top. Only once the flows and the suppression logic exist, because a campaign calendar layered onto an unsegmented list is how DTC brands burn deliverability in a launch quarter.

By day ninety you should see flow revenue rising as a share of total, better engagement on the segments you kept, and a lower cancellation rate if you sell subscriptions. What you should not expect is a moved lifetime-value curve. That compounds across repeat cycles and is judged in quarters.

Our recommendation

Which One Should You Call First?

We are not a neutral party and it would be insulting to pretend otherwise. We wrote this list, we are on it, and we think you should call us. What we can do is show our work, which is what the whole page has been: the tier read in the directory rather than taken off a footer, the results published with brand names on them, and the agencies we left off named with the reason.

The case for YOCTO in DTC is narrow and it is the whole pitch. We do lifecycle and nothing else. There is no paid media team competing for your budget, no development roadmap pushing a flow rebuild to next quarter, and no account tier where you get the junior. What that buys you is the repeat-purchase engine built properly: product-level replenishment timing, segmentation that actually uses your order data, winbacks that know a lapsed subscriber from a discount hunter, and cancellation paths that decide what a subscription is really worth. Healf, ColonBroom, BetterMe, Mira, Jimmy Joy and Gratsi are above, with sources, three of them written up by Klaviyo and Skio rather than by us.

If that is your constraint, the fastest next step is the free audit. It is a real teardown of your account presented live, you keep the scorecard and the gameplan, and there is no obligation at the end of it.

If it is not your constraint, the table above tells you what every other agency here publishes and what it does not, and the section list at the top points you at whichever of our pages matches your category. We would rather you found the right page than the wrong agency.

The Vertical Deep Dives

DTC is a category, not a brief. The mechanics change enough between verticals that we keep a separate, separately verified list for each of the ones we work in.

Frequently Asked Questions

What is the best Klaviyo agency for DTC brands?

There is no single answer, and any list that gives you one is selling. The useful question is what your constraint is. If repeat purchase has stalled, hire a lifecycle specialist. If you are rebuilding the store at the same time, hire a wider team. If you sell subscriptions, hire someone whose case studies mention churn rather than open rates. The table above sorts the twelve by that distinction rather than by rank.

Does a DTC brand need the top partner tier?

Rarely. Tier tells you about an agency’s relationship with Klaviyo, not about whether it understands your repurchase cycle, and plenty of Gold and Platinum partners do better lifecycle work than a larger Elite shop that treats email as one service among ten. Use tier as a credibility floor and a fact you can check, not as a ranking. We keep the tier question on its own page: the best Klaviyo Elite Master agencies covers what the tiers mean, how many agencies hold the top one, and when it is genuinely worth insisting on.

What separates a DTC lifecycle agency from an email agency?

An email agency optimises sends. A lifecycle agency owns the commercial mechanics behind them: when a customer should be asked to buy again, what happens at cancellation, how a subscriber differs from a repeat one-time buyer, and which segments should be suppressed rather than mailed. In DTC the difference shows up in the second quarter, when the campaign lift plateaus and the flows are the only thing still compounding.

Is DTC experience actually a useful thing to filter on?

Barely. Klaviyo is a DTC ecommerce platform, so essentially every agency in its ecosystem serves DTC brands and every one of them says so. The filters that separate agencies are whether lifecycle is the whole business, whether they publish results you can check, and whether their case studies match your commercial model. Subscription and one-time purchase are different businesses even when both are DTC.

How much does a Klaviyo agency for a DTC brand cost?

Most agencies at this level price by proposal, and the market runs from a few thousand a month at boutique shops to five figures at enterprise agencies. YOCTO publishes its packages, which start at EUR 5,500 a month, month to month. The full breakdown of what drives agency pricing is in our Klaviyo agency pricing guide.

Should a DTC brand hire a retention specialist or a full service agency?

It depends what is broken. If the store converts and customers do not come back, a lifecycle specialist goes deeper for less, which is why every agency on this list is one. If you are replatforming or relaunching in the same quarter, a wider team is worth the premium and you should look outside this list, because we excluded full-service agencies on purpose.

What should you ask a Klaviyo agency on the first call?

Ask who is actually in the account weekly, and meet them. Ask what attribution window and model their published numbers use. Ask what they would do in the first thirty days and listen for whether deliverability and data come before design. Ask what they would refuse to do. And ask for the partner tier so you can check it yourself in the directory while you are still on the call.

How fast should a DTC retention programme show results?

Execution ships in weeks: welcome, abandoned cart, post-purchase and winback go live quickly and their leading indicators show inside 60 to 90 days. Cohort lifetime value moves slower because it compounds across repeat cycles, so judge it in quarters. Anyone promising a step change in month one is describing a discount, not a retention programme.
