01Welcome Flow
Your welcome flow explains why someone should want your product and choose your brand.
“Why choose your brand?”
Make the difference clear.

We’ll Turn Your “Reminder Flows”
Into “Acquisition Flows”
That Reduce CAC
and Increase ROAS
We dig through your support tickets, customer feedback, and market to find what makes people hesitate—and what makes them buy. Then we write, design, and build your Klaviyo flows around those findings, with our team managing the work from research to launch.
Get Your Acquisition Flow BlueprintComplete a short brief. Matt will prepare a plan for your flows before you meet.
Does most of your flow revenue come from the first email?
Some drop is normal. Customers who buy leave the flow, so fewer people receive the emails that follow.
But there may be another reason.
Open the second and third emails. Are they giving people new reasons to buy, or are they saying the same thing again?
Revenue
The first email has already reminded them.
If they still haven’t bought,
forgetting may not be the problem.
Why they
don’t buy

I forgot ← Reminder email
Is it worth the money?
Will it work for me?
Why yours?
Are you legit?
They may not believe the product is worth the price. They may not know whether it will work for them, why they should choose yours, or whether they can trust your brand.
Sending another reminder does not answer any of those questions.
Acquisition Flows
are built differently.
Each email answers a different question that can stop the sale.
02Browse Abandonment
Your browse flow helps someone decide whether the product is right for them.
“Will it work for me?”
Explain the formula.
Show the ingredients, amounts, and evidence relevant to their needs.
03Cart Abandonment
Your cart flow answers the questions stopping someone from completing their order.
“Is it worth the money?”
Make the value tangible.
Explain what they get, why it matters, and what supports the price.
04Checkout Abandonment
Your checkout flow resolves the remaining questions before someone buys.
“Can I trust you?”
Give them confidence.
Answer practical concerns with reviews and clear policies.
Example questions and email topics. Your flows are built around your research.
To write those emails, we first find out why your customers buy, why they hesitate, and what questions they ask before ordering.
We find out what your customers need to hear.
Then we build the emails that say it.
We read the conversations your support team is already having.
Invite us into your help desk. We review tickets and chats, speak with your support team, and identify recurring questions, buying concerns, and the answers that help people decide.

I’m looking for sleep support, but does this contain melatonin?
It’s melatonin-free. Here’s the full ingredient label.
That helps. I want to know exactly what I’m taking.

Verified Klaviyo Results
Result: Grew Email From Under 5% to 35–40% of Revenue
David Rose
“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.”
Result: Email Revenue Grew 3.5×
Stephen Martin-Rolsky
“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.”
Result: Nearly 5× the Pre-Agency Email Revenue
Kevin R.
Verified ReviewA 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.
Result: “They’re someone you want on your side and not your competition’s”
Ryan S.
Verified ReviewBefore 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.
Result: Email Revenue Nearly Quadrupled
Doug Brooks
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.”
Result: $10.4M in Email Revenue Since 2024
Austin Laud
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.’”
Result: Added ~10% to Total Revenue Through Campaigns Alone
Caleb T.
“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.”

Result: ~20× Return From Klaviyo Flows
Elliott Rader
“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.”
Result: “The emails have generated millions of dollars”
Louis H.
“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.
It’s a great partnership.”
Result: $615,000+ in Sales From Email Alone
Drew Urquhart
Verified ReviewWorking 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.
