What Elite actually means

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.

01
PROBLEM 01▲ LEAK

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.

02
PROBLEM 02▲ LEAK

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.

03
PROBLEM 03▲ LEAK

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.

04
PROBLEM 04▲ LEAK

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.

05
PROBLEM 05▲ LEAK

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.

06
PROBLEM 06▲ LEAK

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.

Spot yours? That’s where the free audit starts.

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.

01
UNIT ECONOMICS

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.

02
GROWTH LEVERS

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.

03
SCORECARD

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.

04
THE GAMEPLAN

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.

Service surface

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.

Subscription & retention Four areas

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.

Program & channels Five areas

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.

Data & foundations Four areas

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.

Onboarding

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.

Questions Clients Ask Us

Klaviyo lists 6,000+ agency partners. Elite is the top tier - roughly 40 agencies worldwide hold it, on our count of Klaviyo’s directory in August 2026. In practice it means earlier feature access, a direct line to Klaviyo’s product and deliverability teams, and, often, better pricing for you. For you, that’s the difference between an agency that’s proven it can move real revenue on Klaviyo at scale and one that just has the logo on its site.
Most Klaviyo agencies optimize campaigns. We engineer subscription economics - churn, reactivation, and subscriber LTV - on top of a Klaviyo Elite foundation. If your revenue depends on recurring orders, you need a Klaviyo agency that treats retention as a system, not a send calendar. That’s the entire company.
Three things, and they all come back to focus. We’re retention-only - no paid ads, no “full-service” dilution. We’re subscription-specialized - we’ve already solved the exact problems you’re working on, over and over. And we’re small by design - we cap how many brands we take on so we can go deep instead of wide.
It comes down to what we have already seen. Speed - we’ve run this exact play across one subscription brand after another, so we’re not figuring it out on your time. Depth - we solve the subscription and deliverability problems an in-house team can’t. And visibility - we see patterns across far more accounts than any single in-house team ever will, and we bring them straight to you.
DTC and subscription brands roughly in the $5-150M range, mostly US and UK - concentrated in supplements and wellness, beauty and skincare, food and beverage / CPG, and femtech. If repeat purchase and subscription are core to your business, we’re built for you.
A monthly retainer, scoped in hours to what your account actually needs - not per-email or per-campaign pricing. We size it to your account’s complexity and the KPIs we’re moving, then quote it after the free audit, once we know what’s actually broken.
Yes - it’s one of the most common ways brands come to us. We migrate flows, segments, and historical data on a deliverability-safe ramp, so you don’t lose sender reputation or revenue in the move. That dread is the #1 reason brands stay parked on a platform they’ve outgrown; we remove it.
George personally runs the audit and the initial strategy on every account - that’s where the direction gets set. Execution and ongoing strategy development are handled by our expert delivery team.
The honest answer is that it varies enormously. Most run campaigns and build templates. A smaller number own the automation architecture. Very few own the commercial model underneath it - the cohort economics, the churn curve, the payback window - and then build the Klaviyo program to move those numbers. That last one is what we do, which is why our work starts with an audit of your unit economics rather than a content calendar.
Across the market, anywhere from a few thousand a month at boutique shops to five figures at enterprise agencies, and most will not tell you until the third call. Ours is straightforward: packages run EUR 5,500 to EUR 10,000 per month, month to month, with 10-15% off longer commitments. The full breakdown of what drives agency pricing is in our Klaviyo agency pricing guide.
Four rungs. The ladder runs Partner, Silver, Gold, Platinum, Elite. “Certified Klaviyo Partner” is the entry rung and is largely a matter of signing up. Elite is the top rung, held by roughly 40 agencies worldwide on our count of Klaviyo’s directory in August 2026, reviewed by Klaviyo twice a year against managed revenue, certification coverage, published client results and a qualitative assessment. Agencies lose it.
Execution ships fast. Save systems, dunning fixes and core flows go live within weeks, and their leading indicators - save rate, recovered payments, flow revenue - show inside 60 to 90 days. Cohort lifetime value is slower by nature because it compounds over billing cycles; judge that in quarters, not weeks. Anyone promising a step change in month one is describing a discount, not a retention program.
Often yes, and not for the reason you would expect. A good in-house marketer knows your brand better than any agency will. What they rarely have is cross-brand pattern recognition - what a 40% failed-payment recovery rate looks like versus a 12% one, across dozens of subscription accounts. The pairing that works is in-house owning brand and calendar, us owning architecture and economics.
Yes. We run programs across the US, UK and Europe, and the team covers US, UK and EU time zones. Roughly half our client base sells primarily into the US.
