Beauty marketing agency: ten worth shortlisting, grouped by the job they actually do

A beauty marketing agency grows a cosmetics, skincare or personal care brand by owning one of four jobs: retention through email, SMS, loyalty and reviews; social and influencer; brand experiences; or marketplaces. Decide which job your growth gap needs first. Below are ten agencies, each described from its own site and grouped by that job.

Which kind of beauty marketing agency are you hiring?

Most beauty brands that hire the wrong agency did not pick a bad agency. They picked the right agency for a different problem. A brand with strong first-order volume and weak repeat purchase does not need another influencer push, and a brand nobody has heard of does not need a loyalty program yet. Start with the gap, then read only the group that fixes it.

Why beauty brands win or lose on the second order

Beauty is a replenishment category. A serum runs out, a cleanser runs out, a lipstick shade gets reordered, and every one of those moments is either a repeat order on your site or a lost customer on a marketplace. That is why the owned channels carry so much of the economics. Klaviyo's 2026 benchmarks, drawn from more than 183,000 accounts, put the health and beauty placed order rate at 1.02% for campaigns and 1.65% for automated flows. Across all industries, flows are 5.3% of sends and nearly 41% of email revenue.

Proof decides the first order. Bazaarvoice's Shopper Experience Index, published 30 September 2025 from more than 7,000 consumers, found 43% of shoppers look for reviews as their most common step after discovering a product, and 46% named authenticity as their top frustration. Okendo's March 2024 benchmark put the typical review rate at 2.5% to 5% of orders, with the top decile of brands at 22%. A beauty brand with a collection program that sits in the bottom of that range is selling with half the proof its competitors show.

Put those together and the job most beauty brands under-hire for is retention: the flows that time a reorder to the size of the bottle, the review program that turns buyers into proof, and the loyalty economics that keep a customer from switching to a cheaper dupe.

What a beauty retention program should include

If retention is the job you hire for, ask for these pieces by name, because they are where beauty programs differ from generic ecommerce ones.

• Reorder timing by product size. A 30 ml serum and a 100 ml cleanser run out on different cycles; the replenishment flow should know which one the customer bought.

• Quiz and regimen data in segmentation. Skin type, concern and shade answers should decide which products a customer sees next, not just which discount.

• A sample to full-size path. Customers who bought a trial size or a sample set get their own sequence toward the full product.

• Photo and video reviews collected after use, not after shipping, with the incentive offered for any honest review.

• Loyalty built to beat the dupe. Early access to launches and shade drops, and a tier that rewards the regimen buyer, hold customers better than points alone.

• Subscriptions only for true replenishables, offered after the product has proven itself.

Retention agencies: email, SMS, loyalty and reviews

1. BMO Media: retention across email, SMS, loyalty and reviews

BMO Media is a lifecycle marketing agency for DTC brands and a Klaviyo partner. For beauty and personal care brands we run the flows, campaigns, SMS, loyalty and review collection as one program, so the reorder reminder, the review request and the points balance never compete for the same inbox. Jukebox, a natural body care brand selling soaps, lotions and deodorants, came to us with a Q4 strategy built on reused templates. We replaced them with new creative built around the brand's natural ingredients and scents, tested subject lines and send timing before the sale, and primed prospects with education ahead of Black Friday. Email revenue rose 45% year over year in Q4.

If your gap is proof, our reviews and UGC program builds collection, timing and syndication; if it is repeat purchase, our loyalty program agency models the economics before a perk is promised; and the email side runs through our ecommerce email marketing agency.

2. Stimulate

Stimulate describes itself as a customer retention marketing agency for DTC brands specializing in email and SMS retention strategies. Its published case studies include a skincare brand, and it offers separate email automation, email marketing and SMS services. A fit for beauty brands that want an email and SMS specialist rather than a full lifecycle program.

3. Chronos

Chronos describes itself as a Klaviyo Master Elite agency running email, SMS and push retention for more than 500 DTC brands. The scale suits beauty brands that want a large retention team and a deep bench of designers; ask who will run your account day to day.

Social, influencer and PR agencies

4. 5W

5W's beauty practice runs social, influencer, paid media, SEO and generative search visibility as one program for beauty and grooming brands. It comes from a PR background, so the fit is brands that need earned media and creator reach at the same time.

5. Movers+Shakers

Movers+Shakers positions itself as a thought partner for social-first creativity, with a body of TikTok-led work. The fit is beauty brands whose growth problem is cultural relevance on social rather than conversion or retention.

Brand experiences and integrated creative

6. CASE Agency

CASE designs experiences and digital activations for beauty, lifestyle and wellness brands, and lists Rare Beauty among its work. Hire it for launches and moments that need to be seen, not for the flows that convert them afterwards.

7. AMP

AMP's beauty and personal care practice runs social campaigns, digital strategies and consumer-first experiences, with an Aquaphor case study on its site. A fit for established brands that need integrated campaign work.

8. Helen + Gertrude

Helen + Gertrude is a certified women-owned integrated marketing agency with a dedicated beauty section in its work. It pairs data-driven creative with media planning, which suits brands buying campaigns and media together.

Marketplaces and full-service growth

9. Front Row

Front Row describes itself as a global growth partner for marketplaces and commerce, with an Amazon beauty case study for OUAI and separate solutions for lifecycle retention and Shopify development. The fit is beauty brands where Amazon is already a large share of sales.

10. Darkroom

Darkroom describes itself as an AI-native, full-service growth marketing agency for enterprise consumer brands, with a retention service covering email, SMS and lifecycle programs. A fit for larger brands that want acquisition and retention under one contract.

What beauty marketing agencies cost

Almost none of the agencies above publish a rate card, and the ones that quote ranges quote them for different scopes, so a price comparison across groups is meaningless. What you can compare is the model. Social, PR and experience agencies usually bill a monthly retainer plus production and media. Marketplace agencies often add a share of sales. Retention agencies bill a monthly retainer sized to the flows, campaigns and channels in scope, and the platform fees (Klaviyo, Attentive, Postscript, Okendo, Yotpo, LoyaltyLion) sit on your account, not the agency's.

Beauty brands also hire in-house sooner than most categories, because launch calendars move fast and creative approvals sit with the founder. That works for social. Retention is harder to staff, because it needs a strategist, a designer, a copywriter and someone who reads the data every week, which is why many beauty brands keep social in-house and hire out the owned channels.

The useful test is payback. Ask each shortlisted agency what revenue its work should produce in the first 90 days and how it will prove the number is incremental. A retention agency should be able to answer with flow revenue per recipient, repeat purchase rate by cohort and review rate per order; a social agency should answer with reach that converts, not reach alone. Our guide to what email marketing agencies charge breaks the retention pricing models down.

Five questions to ask before you sign

• Which of our products replenish, and on what cycle? A beauty retention plan without reorder timing by product size is a campaign calendar, not a program.

• How do you collect reviews, and what do you offer for them? Since 21 October 2024 the FTC rule on reviews bans incentives conditioned on a positive review, with civil penalties up to $51,744 per violation. A reward for any honest review is allowed; our review request email guide shows the compliant ask.

• Who owns the accounts? Your Klaviyo, Attentive and review platform accounts should be in your name, with the agency invited as a user.

• What will you report every month? Attributed revenue alone flatters every agency. Ask for revenue per recipient by flow, opt-out rate per send and repeat purchase rate by cohort.

• Which beauty brands are you working with now, and what changed for them? A case study with a number and a date beats a logo wall.

If you sell through creators and UGC already, our guide to UGC marketing for ecommerce covers how to turn that content into conversion on the product page, and our sibling post on fashion marketing agencies uses the same grouping for apparel brands.
