The Email Marketing Agency for Beauty Brands Built on Repeat Purchase
In beauty, the product runs out, the routine evolves, and the customer is one promo away from switching. We’re a Klaviyo Elite Partner that builds the email and SMS programs beauty and skincare brands need: driving replenishment, building the routine, and keeping customers loyal in a category where everyone else is discounting.



In Beauty, Acquisition Is Easy and Loyalty Is Brutal.
The category is crowded, the product is replenishable, and customers churn to whatever’s on sale. When beauty brands stall, it’s almost always one of these.
Nothing prompts the refill.
A serum lasts six weeks, a foundation three months - but with no replenishment flow timed to each product’s run-out, the easiest repeat sale you have goes unprompted.
You’re addicted to discounting.
Every email leads with a promo, so you’ve trained customers to wait for the next one and trained your margin to shrink. Loyalty built on discounts isn’t loyalty.
One-time buyers never become regulars.
A first purchase is a trial. Without flows that build the routine and move people to subscription or repeat, your hardest-won customers buy once and vanish.
You don’t segment by what they bought.
Someone who bought a cleanser, someone building a full routine, and someone who hasn’t purchased in six months all get the same email - instead of messaging tied to their products and skin goals.
Your flows ignore your catalog.
Cross-sell and routine-building are where beauty AOV grows, but your post-purchase flows don’t recommend the next product based on what they already own.
New launches go to everyone, equally.
A drop is your biggest revenue moment, but blasting the whole list - instead of sequencing VIPs, lapsed buyers, and category-relevant segments - leaves money on the table.
The Klaviyo Program That Turns a First Purchase Into a Routine.
Beauty retention is about getting customers to refill, expand, and stay loyal without leaning on discounts. We build all three in Klaviyo.
Replenishment & Repeat
Flows timed to when each product runs out, plus the conversion points that move one-time buyers to subscription and repeat - so the refill happens on schedule, not on a whim.
Routine & Cross-Sell
Post-purchase flows that recommend the next product based on what they own, building a full routine and a higher AOV - the opposite of a single-SKU customer.
Loyalty Beyond Discounts
Segmentation by purchase and skin goal, VIP and launch sequencing, and win-back that brings lapsed customers back on value - so you stop renting loyalty with promos.
Your Free Audit Is a Complete Gameplan, Not a Sales Call.
Most agencies sign you, then disappear for eight weeks to “audit” before they tell you anything. We do the opposite. Before you pay a cent — before you even decide — you get a full teardown of your account and the exact plan to fix it, built from your real numbers. Here’s what lands in your inbox.
A Full Unit Economics Analysis
We pull your real numbers from Shopify and Klaviyo — margins, breakeven, retention order by order, and the most you can spend to acquire a customer without losing money. You see exactly where the business makes money and where it leaks.
Every Growth Lever, Mapped
The full set of levers that move LTV — converting one-time buyers to subscription, cutting voluntary and failed-payment churn, reactivating cancellers, lifting subscription AOV. You see which ones actually move the needle.
A Prioritized Lifecycle Scorecard
A flow-by-flow benchmark of your current program — what’s working, what’s broken, what’s missing — scored against brands like yours and ranked by revenue impact. A number, and a reason.
The Complete Gameplan
One prioritized roadmap — which flows to fix, kill, or build, which subscriber segments to split out, and which subscription levers to pull, in order, with targets and trajectory. Not a 40-page deck. A plan you can start tomorrow.
All built from your live Klaviyo, Shopify, and subscription data — never a template.

The Founder Does the Diagnosis
George Kapernaros founded YOCTO to do one thing better than anyone else: turn DTC retention into a measurable system. He sits on the Klaviyo Partner Advisory Council, the Forbes Business Council, and the Fast Company Executive Board — and he personally runs the audit on every account before a single deliverable is complete.
