$10.4M in Email Revenue Selling $7,000 Saunas
Austin LaudCEO of Peak Saunas
Email revenue nearly doubled in 2025, and 2026 is running 65% ahead of the same period last year.
“The benchmark that all of the eCommerce gurus were saying was that email should be 30% of your revenue.
And I was like, ‘Whoa. Mine is basically none.'
So that means I can add 30% to my business if I just implement email.
Long story short, hiring the professionals here, I think basically the first or second month that they came on board, it was somewhere around 23%.
So okay, we're moving in the right direction.
And I think now, over the last 30 days, it's like 48%. Which is a home run.
What they do is not just, ‘Okay, I've created one email with this copy and this design, and I'm going to put it out there.’
It's way more complex than that.
It's like engineering. The name actually makes a lot of sense.
Basically, they're testing a bunch of different variations with copy and designs. It's super intricate.
Out of all the agencies that I've worked with, they're the only ones that have exceeded my expectations.
It's one that I trust, that I'm not having to think about or manage at all.
I literally open the link that they send me once a week or twice a week to see what's upcoming.
And I'm continually blown away, thinking:
‘Wow, I could not do this myself to this level.’”

Email Revenue Accounts For 37% Of Sales Selling $1000 Mattresses
Stephen Martin-RolskyThe Flatpack Co.
“Overall, I believe we’re at either 37% or 38% in revenue attributed to Klaviyo. And I genuinely feel as though we’re just getting started.
The other metric we’re laser-focused on is revenue per recipient. We’re a super high-AOV brand — our average order value is a little over $1,000.
We’ve seen our revenue per recipient go up. When you look at the detailed view in Klaviyo, it’s quite a bit higher — almost double right now — compared with the average in our industry.”
“The first drafts we got back were, I think, less than 36 hours after we signed up. We hadn’t even had our official onboarding call yet.
Those were already ten times better than anything the previous agency had ever done for us. They were also better than anything we had written.
We’re rolling out this new brand messaging, and we hadn’t quite figured out how to put it into words. You guys helped us break through that wall right away.
They understood the assignment.
They actually read the onboarding docs that I sent. We were so impressed.
You guys learn. That’s the key.
The next email is better. And the next email is better...
So I can see that I’m investing in something that will grow over time if we both keep working at it.”

Email Revenue Nearly Quadrupled Selling $400 Work Bags
Doug BrooksCOO at Veto Pro Pac
Klaviyo-attributed revenue grew from $806K before Email Engineers to $3.10M in 2025, while email’s share rose from 15.9% to 34.9%.
“We saw the potential of Klaviyo, but we realized that it was a fairly complex platform where you could do a lot more with it than we were capable of doing.
We all wear a lot of hats in this company. We don’t have somebody with that particular skill set, and the learning curve and the time involved would not have the ROI that we would want.
I think working with your team has really helped us because your expertise was evident from the beginning.
The time you spent to learn about our business was helpful because it saved me the time from having to explain that to you.
And then your ability to present that in a way that really portrayed our brand accurately was extremely helpful.
My experience has been nothing but positive. The results have been great.
And for somebody who’s very busy like I am, to not have to hold your hand the entire time is extremely valuable to me.
And to get the results that we’ve gotten is fantastic.
So yes, of course, I would highly recommend Email Engineers.”

Grew Email From Under 5% to 35–40% of Revenue
David RoseCMO at Prolube Oil
“We were at less than 5% email contribution to revenue... now it’s upwards of 35% to 40%.
We had taken a stab at it ourselves and had some people internally work on the flows and get things set up. There was a baseline.
I think we just needed to take that next step and find somebody who really understood it deeply.
After interviewing several people, we were pretty confident that you were going to be able to take it on.
And it’s worked out.
We’re far more consistent with the campaigns. We’re constantly building out new flows and evolving the flows that are working and not working. The ones that we don’t see working, we’re optimizing.
The quality of the work is great. I think those are the two key components that I look for.
So I definitely would recommend you guys.”

“They’re someone you want on your side and not your competition’s”
Ryan S.CMO at At Home Medical
Before working with Matias and his team we were having trouble with weekly campaigns.
Coming up with fresh (and profitable) ideas week after week is hard. That’s why we decided to search for experts in the field.
We decided to move forward with Email Engineers and we’re glad we did.
We saw results the same week they started creating and sending out emails. Cooperation was easy.
I was afraid this would suck up our time but they have a great process to make everything run as smooth as possible.
Email copy is on-brand and the designs are superb.
They’re someone you want on your side and not your competition’s.
Work with Email Engineers, you won’t regret it.

Added ~10% to Total Revenue Through Campaigns Alone
Caleb T.Founder at STXND
“Matias and his team — you guys — all of your campaigns have pretty much crushed it.
I believe you guys added a complete 10% of our revenue with email campaigns. It’s kind of a no-brainer for me to just have them with me now.
I didn’t want to feel like, ‘Okay, this is still going to be 50% of the work of just doing it myself.’ That was the main thing scaring me from working with an email agency.
You guys keep things super clear and simple. I feel like you guys keep the accountability very clear on who needs to do what and when for things to flow.
That part was a huge relief for me. I don’t feel like I need to be an octopus man. It feels like you guys are responsible for the entire email section.
Before, it was kind of this thing I had to do on the side. But now I confidently feel like it’s an added stream of revenue that we’re considering when we’re forecasting...
“It really — and I’m not just saying this — feels like Matias and his team are literal partners… The optimization and expertise really show, and they really take care of their clients.” ”

$615,000+ in Sales From Email Alone
Drew UrquhartFounder at God The Father
Working with Matias and his team was a game-changer for our brand. Over the course of our partnership, we’ve generated over $615,000 in sales from email alone through Klaviyo.
Even though we’re in a super niche space, his team totally nailed the messaging—our emails didn’t just look good, they resonated and converted.
Honestly, I didn’t even think people checked emails this much anymore, lol, but apparently Matias made ours addictive.
They took the time to understand our audience, and it showed in the results.
Highly recommend Email Engineers if you’re serious about growing your email channel beyond sales and flash offers here and there.

~20× Return From Klaviyo Flows
Elliott RaderCo-Founder at The Gluten Free Brothers
“I can tell you that about 42% of our overall website revenue is coming from email campaigns...
We knew that we were leaving some opportunity on the table with our current Klaviyo setup.
So we found Matias and Email Engineers, and he certainly helped us optimize, think of new content, and really bring expertise to building out flows.
That includes the user experience of customers who go through those flows, how to best reach them, how to best connect with them, the timing, the setup.
It’s all those things.
It really takes an expert like Matias and the team to set these up the way they should be in order to maximize your ROI from email marketing.
They’re responsive. They’re smart. They know what to do to get the job done.”

Nearly 5× the Pre-Agency Email Revenue with a $500 AOV
Kevin R.Owner at BuyRite Electric
A year ago, email was doing fine for us, making up 19% of our total revenue. Not bad, but I knew there was more on the table.
Our at-the-time agency had been stuck for months. That’s when we reached out to Matias and his team.
Fast forward a year, and email is now responsible for 31 to 36% of our total revenue.
Even better, we didn’t run more discounts or sales. Instead, Matias’ team completely changed the way we approach email. Every send had a purpose and every campaign was built to convert.
They took the time to truly understand our audience and what makes them buy.
I think that made all the difference. As a result, email became a consistent and predictable revenue stream. Open rates jumped from 25% to 64% as well.
I’ve worked with agencies before. Most overpromise and underdeliver.
These guys did the opposite. Hiring them was the best decision we made this year.

“The emails have generated millions of dollars”
Louis H.Eight-Figure eCommerce Brand Founder
“Our structure was mainly front-end focused.
We had flows set up, but no real consistent campaigns because I prefer the company structure to be more front-end focused — just gathering new customers.
Structuring an email team was not something I was familiar with, so I was looking for a competent agency to take that over.
Now all of our flows are optimized.
Emails are converting better.
And, of course, we have consistent campaigns now.
Those have generated millions of dollars ever since we started working with Email Engineers.
You guys are great to work with.
It’s pretty much hands-off for me, so it allows me to focus on running the team and on what we’re really good at, which is all the other parts of the business.
So it’s pretty much hands-off and a limited amount of work to get a lot of added benefit.

We research what makes your product worth buying to your customers, and what makes them hesitate. Then we turn those insights into emails that help them justify the investment, and feel confident choosing your brand.
Our team handles strategy, copy, design, implementation, and ongoing Klaviyo optimization.
Give More of Your Subscribers a Reason to Choose You
Schedule a strategy call and we’ll show you where the biggest opportunities are in your Klaviyo account, what we’d change, and how we’d use email to convert more of your existing traffic into revenue.
We build and manage email marketing for eCommerce brands selling products that take more consideration than normal to buy.
You can hire us to research, write, design, and build your Klaviyo flows, or manage your ongoing email marketing, including campaigns, flows, segmentation, testing, and optimization.
Our work gives customers reasons to want your product, answers the questions holding them back, and helps them feel confident choosing your brand.
Because there’s often a lot to resolve between liking a product and buying it.
Customers may compare alternatives, research the details, discuss it with their partner, or work out whether the purchase is worth the money.
That gives email an important job. It can show how the product fits into their lives, explain what makes it worth the price, and provide the evidence they need to feel comfortable buying.
We build your email marketing around those decisions.
We start by figuring out why people buy and why others don’t.
That means studying your customer reviews, support conversations, ads, competitors, past email performance, customer language, and other sources of research.
Then we use those insights to develop the emails, offers, campaigns, flows, and lead-capture experiences your customers see.
We don’t believe the difficult part of email marketing is simply sending more emails. It’s figuring out what your customer needs to see, understand, and believe before they’re ready to buy.
Our goal is to make email as hands-off as possible for your team.
With our ongoing management service, we handle the strategy, copy, design, campaign production, flow development, and ongoing optimization inside Klaviyo.
Your team provides the business context, approvals, and information we need to make good decisions. We handle the execution.
Yes. Email can play a significant role in helping subscribers make their first purchase.
For a product customers might own for years, that means helping people choose the right option, understand its value, and resolve their doubts before buying.
After the purchase, we can also support onboarding, product use, reviews, referrals, and relevant additional purchases, depending on what makes sense for your business.
We begin by understanding the business before trying to change it.
We review your existing Klaviyo account, campaigns, flows, customer data, offers, products, and messaging to identify the largest opportunities.
From there, we prioritize the changes we believe can have the greatest impact rather than changing things simply for the sake of changing them.
We’re best suited for established eCommerce brands selling products worth over $1000.
Price can be part of that consideration. So can comparing specifications, choosing the right model, trusting the quality, or understanding how the product will fit into their lives.
Typically, our clients generate more than $200k per month and already have meaningful traffic, an email audience, and a product people want.
Customer reviews, sales conversations, and past marketing results give us more to work with when identifying what could help more people buy.
Our engagements are customized around the scope of work and what your brand actually needs.
The easiest way to determine fit, scope, and pricing is on a strategy call.
We’ll look at where the largest opportunities are in your current email program and explain what we would recommend doing about them.
We normally get email to account for 32-38% of total sales within 60 days. The exact number depends on your existing email setup, traffic, and how long customers typically take to make a purchase.
An account with missing or underdeveloped flows presents a different opportunity from one with an established email program. And a product people consider for several months needs to be evaluated over a different timeframe from one they buy within a few days.
On the strategy call, we’ll discuss the opportunities we see and what a reasonable timeframe for evaluating progress would look like.
We’ll talk through your current email program, where you believe the biggest opportunities are, and what you’re trying to accomplish.
If we believe we can help, we’ll explain what we would do, how the engagement would work, and what it would cost.
If there’s a fit, we’ll discuss next steps.
