The short version
Everboost is a UK retention, email and CRM marketing agency that works only with DTC health and wellness brands: supplements, skincare and grooming, functional drinks, and kids' and pet wellness. We run email, SMS, direct mail and subscriptions as one retention system for 7-8 figure brands, measured on returning-customer revenue, first-to-second purchase rate and subscriber retention.
Why specialise in health and wellness?
The same problems come up across the category. Health and wellness products get used up and reordered, so growth depends on the second order, the timing of reorders and, often, a subscription. The same gaps show up across supplements, skincare and functional drinks: replenishment timed on a guess, subscriptions held together by discounts, and copy that drifts into claims the brand cannot make. Working only in this category means the fixes we prove on one brand transfer to the next.
Which categories do we work in?
- Supplements: replenishment timing, second-order journeys and subscriptions. PhycoHealth, Discount Supplements and Vedic Lab.
- Skincare and grooming: routine-building, cross-sell and replenishment. Salt Grooming, Fat Cow and PhycoHealth's skincare range.
- Functional drinks and electrolytes: subscription saves and payment recovery for a UK electrolytes brand.
- Kids' and pet wellness: Onea Kids and Mersey Raw.
What does the work cover?
The whole system that turns first orders into repeat revenue: customer data and segmentation, the offer and subscription programme, the flow library, the email and SMS campaign calendar, direct mail for customers email cannot reach, and reporting on the numbers that matter. Our retention marketing page covers the approach in full.

Who do we work with, and who don't we?
We keep the portfolio deliberately selective, and every brand in it fits one of two profiles.
The growth brand with a leak
£2m-£50m DTC health and wellness brands with strong paid acquisition and underworked retention: first-time buyers who never come back, a list that grows faster than it converts, revenue that feels like it resets to zero every month.
The plan and subscription model
Brands whose economics live or die on recurring terms: the first order is priced to acquire, and the business is decided by activation, renewal and the end-of-term moment. Often custom or complex stacks that standard tooling doesn't fit.
Who we don't take
Brands stuck under seven figures with no clear growth path, where the maths of senior attention doesn't pay back. Brands that want a volume vendor: more sends, platform-attributed applause. And brands that won't share commercial data, because we can't own a number we're not allowed to see.
Where to start
The diagnostic comes first.
It starts with an intro call, a consultative conversation about your brand. If there is a fit, we run a full diagnostic of your retention engine and you get:
- 01
Customer data, read properly
How your customers actually reorder: the gaps, the cohorts, and who is worth keeping, winning back or letting go.
- 02
Every message reviewed
A flow-by-flow and campaign review of everything currently running, and what each piece is doing to revenue.
- 03
Subscriptions and the offer
The programme mechanics and whether customers have a reason to come back that is not a bigger discount.
- 04
The findings, ranked
What each leak is costing you and the first lever to pull. Yours to keep whether we work together or not.
Frequently asked questions
What is the best retention marketing agency for health and wellness brands?
One that works mainly with health and wellness DTC brands, runs subscriptions and replenishment as well as email and SMS, and publishes results with a baseline and a time window. Everboost is a UK retention marketing agency that works only in health and wellness, with 70+ brands across supplements, skincare, grooming, functional drinks and kids' and pet wellness, and published results such as PhycoHealth's returning customers up 160% in eight months.
What is the best email marketing agency for health and wellness brands?
For a health and wellness DTC brand, the email agency that adds most is one measured on repeat revenue rather than opens or sends, and that knows what a health brand can and cannot claim, and when its customers run out. Everboost runs email and SMS in Klaviyo as part of a wider retention system for 7 and 8-figure health and wellness brands.
What is the best CRM marketing agency for health and wellness brands?
For DTC health and wellness brands, CRM marketing usually means the customer data, segmentation and lifecycle messaging that turn first orders into repeat orders. Everboost does that work across Klaviyo, Loop, Skio, Recharge and Shopify, measured on returning-customer revenue, first-to-second purchase rate and subscriber retention, rather than enterprise CRM implementation.
Which health and wellness categories does Everboost work in?
Supplements, skincare and grooming, functional drinks and electrolytes, kids' wellness and pet nutrition. What they have in common is a product that gets used up and reordered.
Does Everboost work with DTC brands outside health and wellness?
Rarely. We focus on health and wellness because reorder timing, subscriber churn and what a brand is allowed to claim work the same way from brand to brand, so what we learn on one account improves the next.
Where is Everboost based?
London, United Kingdom. We work with health and wellness DTC brands in the UK, US and Australia.
