The Klaviyo Agency for Fast-Growing DTC & Subscription Brands
YOCTO is a Klaviyo Elite Partner agency running retention and lifecycle programs for DTC supplement, beauty, and subscription brands. One of roughly 40 agencies worldwide holding Klaviyo Elite - trusted by Kilo.co, BetterMe, Orbio.world, Healf, Frøya Organics, Gratsi, Miracare, Elavate & 100+ others.
Klaviyo Elite Partner. One of Roughly 40 Agencies Worldwide
Klaviyo reviews it twice a year, and agencies lose it. Elite is the top rung, not the entry one.
Reviewed, not bought
Klaviyo reviews it twice a year against managed revenue, SMS adoption across the client book, team-wide certification, published client results and a qualitative assessment by the partner team. Agencies lose it.
“Certified” is the entry rung
Most agencies you will compare us against are Silver or Gold. When a competitor says “Certified Klaviyo Partner”, that is rung one of the same ladder.
What it buys you
Earlier feature access, a direct line into Klaviyo’s product and deliverability teams when something breaks, and a seat where the roadmap is discussed before it ships.
Doing $500K+ a Month and Retention’s Still Flat? It’s One of Six Things
We’ve audited hundreds of Klaviyo and subscription accounts. The brands that stall out almost always have the same six problems - and none of them are obvious until someone actually opens the account. Find yours.
Your Klaviyo lifecycle program isn’t built for subscriptions.
The core is there - welcome, abandonment, post-purchase all running. But nobody’s converting one-time buyers into subscribers, winning back the ones who cancel, or nurturing active subscribers differently from first-time shoppers. You have an email program. You don’t have a subscription program.
Failed payments are quietly churning subscribers you already won.
Cards decline, the retry logic barely fires, and recurring revenue you already earned just disappears - month after month, invisible on the dashboard. It’s one of the biggest leaks we find, and one of the easiest to fix.
Your billing reminders are training subscribers to cancel.
Every reminder is a prompt to quit, and most lead with “you’re about to be charged” instead of what they’d lose. Send too many, or word them wrong, and you’re manufacturing your own churn.
Your cancellation flow is a text page, not a save system.
No “here’s what you’ll lose” page, no save offer matched to why they’re leaving, no follow-up. People who’d have stayed for the right offer cancel in two clicks - whether you’re on Loop, Recharge, or Smartrr.
Prospects, subscribers and cancellers are all in the same Klaviyo segment.
“Engaged vs. not engaged” isn’t segmentation. One-time buyers, active subscribers, and cancelled subscribers each need a different message - and right now your best customer sees the same discount as a first-time visitor.
Your Klaviyo flows look like they’re working - until you check the triggers.
Half of them sit in draft, the “shipping” emails fire on a metric that’s been broken for months, and attribution inflates numbers that hide dead automations. You’re paying for a system that isn’t sending.
LTV Parthenon
The framework we built from auditing hundreds of DTC subscription brands. Three pillars decide your customer lifetime value - and the nine numbers underneath them are the only ones we chase. The rest is noise.

A Free Klaviyo Audit That Ends With a Gameplan
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 point, 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, and lifting subscription AOV. You see which ones actually pay for themselves, and which don’t.
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. No vague “you could do better.” 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 the targets and trajectory to hit them. Not a 40-page deck. A plan clear enough to hand to anyone and start tomorrow.
All built from your live Klaviyo, Shopify, and subscription data - never a template.

What Our Klaviyo Agency Runs Inside the Account
This is the surface area we own, end to end, so no part of the program sits waiting on someone else to pick it up.
Klaviyo Subscription & Failed-Payment Recovery
Dunning sequences, card-update prompts and pre-renewal saves wired to Recharge, Skio or Loop. Involuntary churn is the cheapest revenue in the account and most programs never touch it.
Klaviyo Cancellation & Save Flows
Reason-specific save offers instead of a blanket discount, routed on why the subscriber is actually leaving. We took one supplement brand from a text cancel page to 11x more reactivations.
Klaviyo Flow Architecture
The full automation map rebuilt around lifecycle stage rather than campaign calendar: welcome, post-purchase, replenishment, win-back, and the triggers deciding who enters what.
Klaviyo Reporting & LTV Attribution
Cohort lifetime value, payback window and revenue-share reporting built inside Klaviyo, so retention is measured on compounding value rather than last click.
Klaviyo Segmentation & Predictive Analytics
Segments that separate prospects, active subscribers and cancellers using predicted CLV, churn risk and next-order date rather than opens and clicks.
Klaviyo Campaign Management
Planned, produced and sent. Promotional calendar, editorial cadence and send-time discipline that does not burn the list to make a quarter.
Klaviyo Deliverability & Sender Reputation
Authentication, list hygiene, sunset policy and reputation repair. Inbox placement is the precondition for everything else.
Klaviyo SMS & WhatsApp
Segmented, compliant messaging that complements the email program instead of duplicating it. Runs alongside WhatsApp where the audience is there.
Klaviyo Email Template Design & Coding
On-brand, accessible, dark-mode-safe templates built as a reusable system rather than one-off sends.
Klaviyo Migration
From Mailchimp, Omnisend, Listrak, Attentive or Braze. Contacts, historical data, integrations and flows moved without a revenue gap in the transition.
Klaviyo Account Audit & Consulting
A full technical and commercial review of the account: what is broken, what it is costing you, and the order to fix it in.
Klaviyo CDP & Data Integration
Subscription platform, helpdesk, loyalty and reviews data unified into the profile so segmentation can actually use it.
Klaviyo List Growth & On-Site Capture
Forms, incentives and routing that grow a list worth sending to, measured on downstream LTV rather than raw signups.

I Diagnose Every Account Myself
I founded YOCTO to do one thing better than anyone else - turn DTC retention into a measurable system. I sit on the Klaviyo Partner Advisory Council, the Forbes Business Council, and the Fast Company Executive Board - and I personally run the audit on every account before a single deliverable ships.
