Best Klaviyo Agencies for Beauty & Skincare Brands (2026)

We went through the Klaviyo partner directory agency by agency and checked thirty of them against three criteria. Nine cleared. This is the list, with the partner tier we read off Klaviyo’s own directory on 22 September 2026 rather than off anybody’s footer, and the published beauty work each one can actually show you.

Key Takeaways

• Partner tier is checkable in ninety seconds and a surprising number of footers are out of date. Every tier here was read in the Klaviyo directory on 22 September 2026.
• Most “beauty” agency claims do not survive a check. Klaviyo’s directory lets agencies tick a “Retail: Apparel & Beauty” box, and they tick it wholesale. Twenty-one of the thirty we checked had nothing on their own site to back it.
• One agency on this list is not a Klaviyo partner at all. Velour Agency does good, narrow work for clean beauty brands, and it does not appear in the directory. Both things are true and you should know both.
• Beauty breaks segmentation in a way other categories do not. Shade, formulation and variant data decide whether a replenishment reminder lands or insults the customer.
• A routine is not one product. A customer buying a cleanser, a serum and an SPF is on three different repurchase cycles, and a single generic winback treats all three as one.
• Only three of the nine publish a beauty result with a number and a brand name on it. Two more publish named beauty case studies with no figure, and four publish nothing. That is the fastest filter on this page.
• Specialism and scale are a real trade-off here. The narrowest agency on this list works only with clean beauty; the broadest will also rebuild your Shopify store. Neither is the right answer until you know which constraint you are solving.

How We Judged These Agencies

Three criteria, and all three are things you can check yourself rather than take on faith.

1. Verified Klaviyo partner tier. Read from the Klaviyo partner directory at connect.klaviyo.com on 22 September 2026, not from the agency’s own site.
2. A named beauty or skincare practice. The agency has to say so on its own site, in its own words, with beauty work behind it. A directory industry checkbox does not count, for reasons set out below.
3. A published beauty client result. A case study on their own site, with a number and a named brand, that you can open and read. Where there is none, the table says so.

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

Tiers and practices were re-checked on 22 September 2026. YOCTO wrote this list and is on it, judged by the same three criteria.

YOCTO

Klaviyo Elite Master, 2025-2026, and one of two Elite-tier agencies here with a dedicated beauty and skincare practice. 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, with beauty and skincare as one of three named verticals alongside supplements and femtech.

The argument for YOCTO in beauty is the replenishment maths. Most beauty programs are built as if a customer buys one thing; YOCTO builds them around the routine, which means product-level repurchase timing, variant-aware segmentation, and winbacks that know the difference between a lapsed serum buyer and a lapsed sample buyer. The named clients on the beauty and skincare practice page include Evereden, Boujee Hippie and Frøya Organics.

Best for

Beauty and skincare brands where repeat purchase, not acquisition, is the constraint, and where the catalogue is big enough that generic flows have stopped working.

Not for

Brands that want their store rebuilt at the same time. YOCTO does lifecycle, not Shopify development. Two agencies further down this list do both.

UN/COMMON

Klaviyo Elite Master, and the deepest published beauty portfolio on this list by a distance. UN/COMMON runs Beauty & Cosmetics as a formal case-study category rather than a token example, and the names in it are ones you will recognise.

Their beauty work includes Rare Beauty by Selena Gomez, where they ran the go-to-market lifecycle strategy for an international launch on roughly a month of preparation; Dermalogica, which came to them with no built-out automated flow infrastructure and wanted repeat purchasers and loyalty; Wander Beauty, replatformed from Magento to Shopify 2.0; and Beautyblender, a conversion-optimisation and ecommerce rebuild. Ursa Major sits in the same category on the conversion side.

Worth being clear about what that portfolio means. UN/COMMON is a full-service Shopify Plus agency where lifecycle marketing is one practice among design, replatforming and conversion work. For a beauty brand that needs the store and the email program moved together, that is the argument. For one that only wants lifecycle, it is a bigger engagement than you need.

Best for

Established beauty and cosmetics brands doing a launch or a replatform where the email program has to move at the same time as the store.

Not for

Small brands wanting a lifecycle-only retainer. You would be buying the narrow slice of a wide agency.

Ivy & Co. Studio

Klaviyo Platinum Master, and the only agency here whose entire positioning is beauty. Their own line is “thoughtful strategy, content, and creative for beauty and wellness brands”, and the client wall backs it: Haus Labs, Florence by Mills, DIBS Beauty, Coco + Eve, Herbivore, Odele, Pipette, by/rosie jane, NuFACE, GHD Hair, VI Peel and Juvia’s Place.

That is an unusually dense beauty roster for a small team, and it covers the sub-categories that actually behave differently from one another: colour cosmetics, haircare, skincare and devices. They publish a +120% increase in email revenue for Juvia’s Place, and 49% of revenue attributed to email for Vitality Institute.

They are a small group, which is the trade-off. If you want a large bench and a named account team of six, this is not that. If you want people who have built a shade-aware segmentation model before because they have done it a dozen times in your exact category, it very much is.

Best for

Colour cosmetics, haircare and skincare brands that want category fluency from day one and do not need a large agency around it.

Not for

Brands needing paid media, development or a full-funnel team under one roof.

Stimulate

Klaviyo Gold Master, and the strongest published proof per client on this list. Stimulate runs a Skincare and Beauty case-study category rather than a single token example, covering TEMPTU, Silver Mirror, Skinmedix and Editor’s Pick.

The Skinmedix case study is the one to read: 381% growth in email revenue and a 47% increase in lifetime value, published with the brand named. Silver Mirror, a facial bar, is credited with 213% list growth in the first two months. Whatever you make of any single number, the pattern of publishing them with brand names attached is rarer than it should be.

Best for

Skincare brands that want to see category-specific work before signing, and clinic or facial-bar models where retail and service revenue mix.

Not for

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

The Media Captain

Klaviyo Gold Master, based in Columbus, Ohio, with a beauty, skincare and cosmetics practice. The unusual thing about them is that they own a beauty brand themselves: DermWarehouse, which they have grown to more than five million in annual revenue and over one hundred thousand customers, and which they say draws more than forty per cent of its revenue from email.

That is a genuinely different qualification from a case study. An agency running its own profit and loss in your category has felt the cost of a bad send. Their published client work includes Boss Gal Beauty at a 44% conversion rate increase.

Best for

Beauty brands that want an operator who has carried the inventory risk, and brands with a retail or clinic footprint as well as ecommerce.

Not for

Brands outside North America wanting local hours and local deliverability knowledge.

Sticky Digital

Klaviyo Platinum Master, retention only, and by their own description a hundred per cent female-led. Beauty is one of four verticals they name, alongside wellness, food and beverage, and apparel, so this is a retention specialist that works in beauty rather than a beauty specialist.

That distinction matters less than it sounds. Their public position is that segmentation architecture, suppression logic and loyalty integration come first and campaigns are layered on top, which is the right order for a category where over-mailing burns a list fast. They publish no individual beauty case study with a named brand and a number, which is the one gap in an otherwise strong profile.

Best for

Brands that want a retention-only team and are comfortable being one of several categories on the roster.

Not for

Buyers who need to see a beauty result with a brand name on it before they will sign.

Roswell NYC

Klaviyo Platinum Master and a Shopify Platinum Partner, based in New York. Beauty is the first industry they name on their own site, ahead of fashion, haircare, jewellery, luxury, wellness and consumer packaged goods, and haircare appearing separately is a reasonable signal that the distinction means something to them.

Set expectations correctly, though. Roswell is a full-service commerce agency: retention marketing is one of roughly fourteen services listed alongside branding, photography, custom development, subscription commerce and migrations. A beauty brand hiring them for lifecycle alone is hiring a fraction of the offer. A beauty brand that needs a Shopify build, photography and the email program treated as one project is hiring exactly the right shape.

Best for

Beauty and haircare brands in the middle of a rebuild or migration who want retention designed in rather than bolted on afterwards.

Not for

Lifecycle-only retainers, where a specialist will go deeper for less.

Forge Digital Marketing

Klaviyo Silver Master, with a dedicated skincare marketing practice covering Klaviyo lifecycle work and Shopify together. The lower tier reflects scale rather than quality: Silver Master still means an agency that fully manages client accounts rather than referring them on.

They position across the full funnel rather than retention alone, which cuts both ways. If you want one team on paid, SEO and email it is a fit; if you want a specialist who only touches lifecycle, it is not. They publish no named beauty client result.

Best for

Smaller skincare brands that want acquisition and retention under one roof and do not yet need a dedicated lifecycle team.

Not for

Brands with a large catalogue where variant-level segmentation is the whole problem.

Velour Agency

The narrowest positioning here by some distance: done-for-you Klaviyo systems for sustainable skincare and clean beauty brands, and nothing else. For a clean beauty brand that wants an agency fluent in its specific claims environment, that focus is the whole argument.

It comes with a caveat we are not going to bury. Velour Agency does not appear in the Klaviyo partner directory as of 22 September 2026, so there is no tier to verify and no directory profile to read. That is not evidence of bad work, and plenty of good operators are not in the programme. It does mean the single fastest check available to you returns nothing, so the diligence falls back on references and a look at the actual account.

Best for

Clean beauty and sustainable skincare brands that value category fluency over programme credentials.

Not for

Buyers whose procurement process requires a verifiable partner tier.

Why Most Beauty Agency Claims Do Not Survive a Check

Twenty-one of the thirty agencies we checked surfaced against beauty and skincare searches without having beauty on their own site in any form we could verify. The mechanism is worth understanding, because it is the same mechanism that fills every other list like this one.

Klaviyo’s partner directory lets each agency describe itself and tick industry boxes. One of those boxes is “Retail: Apparel & Beauty”. It is self-selected, it is never audited, and it bundles two unrelated categories into a single tick. Search the directory for “beauty” and you get dozens of agencies whose only connection to the category is that checkbox.

Two concrete examples from this check, both of which we would have had to include to reach a longer list. One agency’s directory profile names beauty inside its stated niche; its own site leads with fashion, homeware and a supplement brand, and there is no beauty client on it. Another describes supporting brands “across the luxury, beauty, food and fashion industries”; its published work is a menswear label, a sneaker retailer, a cookware brand and a fashion house. Neither is dishonest, exactly. Both would have been filler.

The ninety-second version of this check, if you are doing it yourself: open the agency’s own site, look for beauty in the industries or work section, and try to open one beauty case study with a brand name on it. If the only place beauty appears is a directory tag, you have learned what you needed to know.

What a Beauty Retention Program Has to Solve

The reason category experience matters here is not branding. It is that four or five things about beauty break the default Klaviyo setup, and an agency that has not met them before will ship a program that looks correct and underperforms quietly.

A routine is several repurchase clocks, not one. A cleanser runs out on a different schedule from a serum, and an SPF on a different one again. The default replenishment reminder fires on order date, which means a customer who bought three products gets one reminder timed for the average of three different cycles, and it is wrong for all three. Product-level timing is the fix, and it needs clean variant data to work at all.

Shade and formulation are identity, not attributes. Recommending the wrong foundation shade or the wrong formulation for a skin type is worse than recommending nothing: it tells the customer the brand was not paying attention. This is why variant-level segmentation matters more in beauty than in almost any other category, and why so many programs quietly cap out. The data is usually there in Shopify; it is just not being passed into segments.

Sample and discovery buyers are a different population. Someone who bought a discovery set is not a lapsed customer when they do not reorder in thirty days; they are a customer mid-decision. Treating them with the standard winback sequence trains them to wait for a discount. They need education and a shade or formulation match, not a coupon.

The second purchase is won with education, not promotion. In skincare especially, the reason a first-time buyer does not return is often that they used the product wrong, stopped too early, or did not know what to pair it with. Post-purchase education sequences do more for repeat rate here than any campaign calendar, and they are the thing most commonly missing.

Launch cadence burns lists faster in beauty than anywhere else. Category norms push frequent drops, and frequent drops push frequent sends. Without suppression logic and engagement-tiered sending, a brand can spend a year building a list and burn its deliverability in one launch quarter.

None of that is exotic. It is simply the difference between an agency configuring Klaviyo and an agency that has watched these five things go wrong in your category before.

Specialist or Full Service?

The three criteria above tell you who is real. They do not tell you which one fits, and the
single biggest fit question in this list is not tier or category depth. It is whether you are
buying a lifecycle team or a whole commerce team.

Read that table against your actual constraint rather than your wish list. A brand whose
store converts fine and whose customers simply do not come back is buying the wrong thing if it
hires a full-service agency, and will pay for strategy, design and development capacity it never
uses. A brand replatforming in the same quarter is buying the wrong thing if it hires a
lifecycle specialist, because the handover between the agency rebuilding the store and the
agency owning the customer data is exactly where flows break.

The honest summary: five of the nine are lifecycle-first and four sell a wider engagement.
Neither group is better. They answer different questions.

What the First 90 Days Should Look Like

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

Weeks one to three: the audit and the data. Deliverability and list health
first, then a proper look at what product and variant data is actually reaching Klaviyo from
Shopify. In beauty this is usually where the real problem is found, and an agency that wants to
start by redesigning templates has told you something about its priorities.

Weeks two to six: the flows that pay for the engagement. Welcome, abandoned
browse and cart, post-purchase education, and a first pass at replenishment. Replenishment is
the one that needs the product-level timing discussed above, so expect it to be staged rather
than switched on whole.

Weeks four to ten: segmentation and suppression. Engagement tiers, sunset
rules, and the variant-aware segments that make beauty recommendations land. This is 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
beauty brands burn deliverability during launch season.

What you should be able to see by day ninety: flow revenue rising as a share of the total,
better engagement on the segments you kept, and a replenishment sequence that fires per product
rather than per order. What you should not expect by day ninety is a moved lifetime-value curve.
That compounds across repeat cycles and is judged in quarters, not weeks.

Which One Should You Call First?

If you want the deepest published beauty portfolio and you are moving your store as well as your email, call UN/COMMON. If you want people who work in beauty and nothing else, and you value that over agency size, call Ivy & Co. Studio. If you want published proof in skincare specifically before you talk to anyone, start with Stimulate. If you want an agency that has run a beauty brand rather than only advised one, call The Media Captain. If you are a clean beauty brand and credentials matter less than category fluency, Velour Agency is the specialist, with the directory caveat above.

If the constraint is that repeat purchase has stalled and the catalogue has outgrown its flows, that is the problem we built our beauty practice around, and the free audit tells you what is wrong whether or not you hire us.

Frequently Asked Questions

Do you need a beauty specialist, or will any Klaviyo agency do?

A generalist can build the flows. A specialist knows the category maths: that shade and formulation matter more than price in a replenishment reminder, that a routine is several products bought on different cycles, and that a first-time buyer of a serum behaves nothing like a first-time buyer of a supplement. That is why every agency here names beauty on its own site rather than treating it as one more logo on the wall.

How many Klaviyo agencies actually have a beauty practice?

Fewer than the directory suggests. We checked thirty and nine cleared all three criteria. The gap is almost entirely the “Retail: Apparel & Beauty” industry checkbox, which agencies self-select and nobody audits, and which bundles apparel and beauty into one tick. Treat it as a filter for building a shortlist, never as evidence.

How do you verify the partner tier of a Klaviyo agency?

Look the agency up in the Klaviyo partner directory at connect.klaviyo.com and read the badge on its profile. Do not trust the website footer. Every tier in the table above was read there on 22 September 2026, and one agency on this list does not appear in the directory at all, which is the sort of thing a footer will never tell you.

What does the Master part of the tier mean?

Below Elite, each Klaviyo partner level splits into two tracks. Master is for agencies that fully manage client accounts, Advisor is for referral-focused partners. Elite exists only in the Master track. So Gold Master and Platinum Master both mean the agency manages accounts rather than referring them on.

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

It depends on what is actually broken. If the store converts and the problem is that customers do not come back, a lifecycle specialist will go deeper for less money. If you are replatforming, relaunching or rebuilding at the same time, splitting that across two agencies creates a seam exactly where your customer data lives, and a full-service team is worth the premium. This list contains both on purpose, and each entry says which it is.

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

Most agencies at this level price by proposal, and the range across 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.

What should a beauty brand ask an agency before signing?

Ask which beauty clients they have run, and to see the flows rather than the deck. Ask how they handle shade and variant data in segmentation, because that is where beauty programs usually break. Ask what happens to your replenishment timing when a customer buys three products on three different cycles. And ask for the partner tier so you can check it yourself.

How fast should a beauty retention program show results?

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