Fact 1: You do not have a traffic problem. You have a margin per customer problem.

As you scale, CAC (cost to acquire a customer) rises until the first order barely breaks even. That’s the invisible ceiling most brands hit:

You’re spending $50 to make $50, so growth stalls. 

The solution isn’t spending more on ads. It’s to earn more per customer, so you can afford to outbid, outspend, and outgrow your competitors. 

When your earn more per customer, you escape the CAC trap and unlock a new ceiling for paid media growth.

Here’s how to know if you have this problem:

  1. You spend more, without really making more…
  2. You keep testing creatives, but CPAs keep climbing…
  3. You’re unsure why customers only buy once and how to fix it…

 

How we can solve your problem:

  • Shift your focus from ‘Klaviyo revenue’ to LTV:CAC, cohort retention, and earning more from every single customer.
  • Design lifecycle systems that multiply value after the first order (so every buyer is worth more, faster).
  • Use experimentation to prove incremental lift, so you can scale paid with confidence.

Fact 2: You’ve likely been “burned” by Klaviyo agencies before.

If you’re like most founders we talk to, this isn’t your first rodeo. You’ve hired agencies. Maybe even multiple. And it went like this:

“We paid $4.5K/month and still had to do half the work.”

“They sent emails, but didn’t move revenue.”

“Open rates looked fine. Conversions were flat.”

“They didn’t get our product, our brand, or our customer.”

“Took 3 months to onboard, and by then we’d lost momentum.”

You didn’t get a roadmap. You didn’t get ownership. You didn’t get ROI.

Thay talked a big game, but all you got was busywork.

And now you’re paying the price. 

Fact 3: One more “Klaviyo audit” won’t help.

Most agencies show up with a generic audit, a few templates, and a junior strategist.

They point at flows you “don’t have yet” – but ignore your margins, your product, and your customer journey.

What you REALLY need someone is who understands your funnel, your brand, and your economics, and turns that into action this week, not next quarter.

That’s why YOCTO works differently

We start with a 45-60‑minute Strategy Activation™ (a  working session meant to uncover your #1 retention opportunity). Within 48 hours, you get a focused roadmap:

  • What to fix
  • What to test
  • What the impact will be
  • And exactly who’s doing what

Then we execute.

We onboard in a day. Lock owners and deadlines. And by Day 6, you’re seeing live segmentation, optimized flows, experiments, and campaign lifts — not slide decks.

We own your entire lifecycle stack: Email, SMS, WhatsApp, Direct Mail, Push, In-App – whatever it takes to turn one-time buyers into loyal repeat customers.

This is full-funnel retention design built around your product, your funnel, and your LTV targets.

Or maybe I’ve got it all wrong, and you’re already winning. But you’re still looking for an edge to take you to the next level.

Either way, YOCTO’S properietary approach might be the competitive edge you need.

We’ve helped brands just like yours overcome every lifecycle challenge they’ve faced – or will face  – especially in health, wellness, supplements, and CPG.

And we’re ready to do the same for you.

So if this sounds like what you’re looking for, then I’ve got an offer for you below…

We earn you TRIPLE our fee in as little as 90 days – or your money back.

HOW IT WORKS

Over the course of the next few months, we'll roll out a systematic, perfectly structured, and comprehensive 3-phase retention system designed to make you #1 in your market. The goal is complete market domination and anything less is considered a failure.
PHASE 1 Stop churn before it starts

We rebuild onboarding so new customers stick, by running three post‑purchase tracks in sync.

Transactional: Clean, fast, trusted. Messages that calm nerves and set expectations—so everything feels easy and under control.

Marketing (Pre‑delivery): Turn the wait into momentum. People know what Day 1 looks like and feel an early win—before the box arrives.

Marketing (Post‑delivery): Make the product a habit. Plain‑English guidance and timely check‑ins so progress feels obvious. The second order feels natural, not forced.

These are not cookie‑cutter “thank you” flows. The best part? That’s just Phase 1.

Outcome: fewer early cancels, more second orders, happier customers, fast.

PHASE 2 Make them love you (proactive retention)

We give people reasons to stay before they think about leaving.

Surprise & delight: Quiet moments that make customers feel seen. Small touches, big impact.

Digital IP: Members‑only value that lives beyond the box. Useful, simple, and actually used.

Progress & recognition: Friendly nudges and small celebrations that make momentum visible. When progress is felt, loyalty follows.

No more discount spam that cheapens your brand. This is a proven, repeatable system that makes customers feel cared for.

Outcome: more usage, higher satisfaction, longer stays, stronger LTV.

PHASE 3 Save the ones who want to leave (reactive retention)

We remove the real blocker—fast—and let people feel in control the whole time.

Smart cancel: When someone heads for the exit, we understand why and open the better path. If cost, pace, or fit is the issue, we guide them to a plan that matches their reality—no pressure, no maze. Staying becomes the easiest choice because it finally feels right.

Payment saves: Failed payments shouldn’t feel like a fight. We give a calm, one‑tap way to fix details and keep everything rolling—same tone, same brand, zero panic. It’s a soft safety net that quietly protects revenue without annoying anyone.

Winbacks: If they still leave, the door stays open. We reach out when timing is on our side, with a message that actually speaks to their reason for leaving. No guilt trips—just a clear “this might fit better now” and a single, simple step to return.

Outcome: fewer losses today, more come‑backs later, and revenue you used to leak—kept.

HERE ARE SOME OF THE NICE THINGS PEOPLE SAID ABOUT US

Matteo Grassi Co-Founder Popup | Ex Shopify September 14, 2021, Matteo was YOCTO’s client
A true master in retention marketing.
I have been working with many agencies and freelancers but George has brought the best results combined with a outstanding work ethic.
Erikas Plotkinas CMO | Kilo.health June 1, 2022, Erikas was YOCTO’s client
George really knows what he is doing. Also, he is a super hard-working guy who puts many hours into making things happen. He helped Kilo.Health improve conversion rates and helped our internal team with leveling up their skills.
Mykolas Mickus CMO at ZENOO January 6, 2022, Mykolas was YOCTO’s client
I've worked with George on two projects now, and he's great. First, he doubled the conversion rates of our cart abandonment emails. Then he created advertorials for us that performed so well that we were able to scale our acquisition to new heights. This is one of the easiest recommendations I make because I know he will deliver results. Plus, he's easy to work with and an overall nice guy.

And last but not least, I love his honest approach to doing business. If he can deliver it - he will do it. If he can't - he will say that. He won't try desperately to oversell his services as many other people do.
Vasilis Skolikis CMO | FitBuddy January 20, 2023, Vassilis was YOCTO's client
George is the creme de la creme of lifecycle email marketing. With the help of YOCTO & George, we managed to create, communicate and deliver value to a target market at a profit with top-class email marketing. George has amazing work ethics and he is really data-driven on his decisions.
Ieva Vaitkunskaitė Head of D2C Growth | Yamo.bio September 7, 2022, Ieva was YOCTO’s client
I have a chance to work with George this year and I can say only good words about him and the work he did! George was helping our company with conversion copywriting and email marketing. His knowledge, experience in both topics & insights that he shared with us after the audit and during the consultation sessions were very valuable. Would definitelly recommend to work with him, especially if you want to level up your game in email marketing.
Kieren Quarmby CEO at Digital Vikings October 4, 2021, Kieren was YOCTO’s client
I worked with George to take a deep dive into our email strategies, campaigns and analytics for our D2C eCommerce company. George did a phenomenal job and we came out the other end of our time together in a much healthier position.
Katya Samotoi Managing Partner | Viceroy Group June 7, 2022, Katya was YOCTO’s client
I've been collaborating with George for quite a bit now and have to say - he is a retention marketing ninja. He takes Email Marketing to a whole new level! 100% recommend George to anyone.

Besides the amazing job he is doing, he is also a fantastic and easy-going human.
Augustas Vinikas Email Marketing Lead | Keto Cycle September 14, 2021, Augustas was YOCTO’s client
I have been working with George for quite some time now and can only say the best words. Not only have we seen tremendous positive impact on our results, but George is also a great mentor to our colleagues.
Spiros Petrou CEO | Red Raven Eyewear May 19, 2022, Spiros was YOCTO’s client
I have been working with George for more than 2 years and I can tell he is a true expert on his subject.

He is really organised with his work and always consistent on meeting his deadlines.

The ROI was more than 10x for our company.

I would highly suggest to anyone serious about e-commerce to work with George.
Savvas Zortikis Co-founder & CEO of Viral Loops (acquired) April 11, 2022, Vasilis was YOCTO’s client
We're very happy to have worked with George and his team on one of our e-commerce projects! He's a real expert in email marketing and e-commerce marketing in general. We saw a positive ROI within 30-45 days of starting. Very organized, easy to work with, he really goes the extra mile and it shows. I highly recommend reaching out to him if you'd like to go to the next level.
Evaldas Einikis Growth Lead for DTC Brands January 4, 2022, Danas was YOCTO’s client
George knows his stuff :). Need a converting copy? He’ll do it. Want to improve your email marketing game? He’ll help.

Honestly, from the beginning of our collaboration results keep going up! What I really like about his work is his attention to detail and that he dives deep to understand the customer.
Great guy to work with if you want to get to another level.
Danas Kurlavičius Head of Email Marketing | FastingSolutions November 23, 2021, Danas was YOCTO’s client
Exceptional attention to detail. Expert in email marketing. Content converts really well.
Alvydas Opulskis CEO at HW.Media September 14, 2021, Alvydas was YOCTO’s client
"Amazing" is the word that first comes to mind when asked to describe George Kapernaros. He is an awesome conversion copywriter and a great email marketing specialist.

Fact: In 2025, you need something more than someone to schedule your emails.

Let's be honest. The way most email marketing agencies operates is more or less this:

“We will add 30% revenue by email” (if only that were true…)

They send more emails, but conversions stay flat, and you’re left wondering if email even works.

 

They don’t understand your brand, your customer, or your positioning,  so you end up redoing half their work yourself.

In short, they dramatically overpromise, but in reality, you
get mediocre, uninvolved execution that binds you to deliverables that might or might not even be right for you.

Or worse,  you hand retention to a generalist…

An in-house team juggling a dozen other tasks…

A freelancer who’s learning on your dime…

Or a “full-service” agency that treats lifecycle as an optional upsell, not a growth engine.

They talk about what your brand could be, but they’ve never actually built retention systems that work. They don’t have the reps, the data, or the scar tissue.

They can’t see what we see, because they haven’t lived it 100+ times across the exact same challenges you’re facing now.

And this is precisely why we’ve launched this offer.

At the end of the day, YOCTO wins when you win.

And if I can promise you one thing, it’s this: My team and I will treat your company like my own.

– George Kapernaros, CEO of YOCTO
