The honest version of this page: we are a retention agency and we appear on this list. Weigh our entry accordingly. The list exists because beauty is the vertical where agency selection is hardest to get right: the technical work (replenishment, sampling funnels, routine expansion) has to coexist with a creative bar most retention shops cannot clear, and few agencies have both.
How this list was put together
A practitioner's list: agencies whose work we have seen and rate from operating in the same market. Nobody paid for placement, there is no ranking order, and our entry carries the same fit note as the rest.
Agencies we rate for beauty and skincare
Homestead Studio
A Klaviyo and Shopify Plus specialist for higher-AOV lifestyle brands, with creative baked into the retainer rather than added on. That composition is exactly what beauty demands: the design work is not a deliverable, it is the product. The first fit to evaluate for a prestige or design-led brand, where every send has to hold up next to the best inboxes in commerce.
Magnet Monster
A Klaviyo Elite Master partner with 300+ DTC brands and full-service retention across email, SMS, WhatsApp, and direct mail. The consumables mechanics that drive skincare retention (replenishment cadence, subscription lifecycle) are core competence at that scale, and the breadth suits beauty brands running loyalty and multi-channel programs.
Underground Ecom
A UK-based Klaviyo Elite Master partner and Klaviyo's EMEA Agency Partner of the Year 2025, data-led and revenue-tied. A fit for growth-stage beauty brands that want measurement rigor while scaling fast, and for teams that want the business case visible on every initiative.
Retention Harbor
That is us. We build Klaviyo retention systems for DTC brands, beauty among them, on the architecture in our beauty setup guide and skincare flows guide: zero-party data capture, sample-to-full-size funnels, usage-timed replenishment, routine expansion. Retention only; if you want paid and creative production under one roof, a fuller-service shop fits better. The right conversation with us is a brand whose acquisition works and whose second-purchase rate does not.
How to choose between them
Beauty selection is two filters run in order, as covered fully in our beauty agency selection guide:
- The creative filter first: the last ten beauty emails they shipped (not the portfolio), judged against the prestige brands in your customer's inbox, plus confirmation the portfolio designer works your account, their revision turnaround, and how brand guidelines get onboarded.
- The mechanics filter second: can they walk a sample follow-up sequence for two different product types, per-product replenishment timing, and a routine-expansion path without preparation.
Most agencies pass one filter. The shortlist is whoever passes both for your brand specifically. If two finalists pass both, a paid test brief (one campaign email from your real launch assets) resolves it faster than reference calls.
How to run the process
- Week 1: run the 30-minute self-audit, and pull your own numbers: sample conversion if you sample, routine depth, repeat rate.
- Week 2: calls, same questions to all, creative samples requested up front so you review before the call rather than live on it.
- Week 3: proposals, judged on creative scope specificity: count the designed emails, confirm flow creative is in scope, confirm who owns the template system.
Terms worth checking before signing
- You own the account, the flows, and the template system. Built in your Klaviyo, under your login, yours if you part ways.
- Creative scope in numbers: designed campaigns per month, flow refresh cadence, revision rounds included. Beauty retainers at the same price diverge 2x on this.
- Out clause at 60 to 90 days, standard.
- Reporting terms: attribution window named, clicks over opens, sample-funnel and routine-depth metrics in the monthly report rather than vanity opens.
What to include in your first inquiry
Monthly revenue range, list size, category mix (skincare, color, hair), whether you sample or run discovery sets, your subscription attach rate if any, and a link to your brand guidelines. An agency fluent in the vertical will respond with questions about your routine architecture and data capture. A generalist will respond with a campaign calendar.
Frequently asked questions
What matters more in beauty, strategy or creative?
The honest answer is that creative is the constraint. Strategy gaps can be closed in a quarter; a creative capability gap usually cannot, and in this vertical design quality is a conversion variable.
What does a beauty retention agency cost?
The standard mid-market range, roughly $6,000 to $12,000 a month, with creative depth the main variable inside it. Full comparison against in-house in our in-house vs agency guide.
What benchmarks should we hold an agency to?
Category orientation numbers: opens around 30.5% and clicks around 1.4 to 2.2% for health and beauty, top-decile flow conversion near 5.4%. Judge on clicks and revenue per recipient, since Apple MPP inflates opens, and ask what attribution window produced any number in the deck.
Is a paid test brief a reasonable ask?
Yes, and paying for it is what makes it reasonable. One real email from your real assets beats every reference call on the list.
