Most brands focus on getting new customers. We help you make more money from the ones you already have – through emails, SMS, and proven retention strategies.
So, what's our deal?
TL;DR version
PS: We recommend acting quickly. Due to capacity limits, we take on a maximum of 3 new clients each month, with others being placed on a waitlist.
Full version (if you're brave enough…)
Do you run an e-commerce store and want to achieve the following in the next 90 days?
Collect thousands of new potential customers for your database every month,
Convert these leads into paying customers,
Turn them into loyal fans of your brand who keep coming back,
Reduce your customer acquisition costs (CAC)...
...and ultimately transform your e-commerce store into a true household name?
If so, grab a coffee and get comfortable, because this might just be the best sales letter you’ve read in a while.
Do I have your attention?
Great.
Now, you might be thinking, “Sure, that sounds amazing, but it can’t be that simple. What's the catch?” and I totally get it.
What business owner with common sense wouldn’t be a bit skeptical of such a bold claim?
Well, it’s not easy — but over the next few minutes, I’ll prove to you that it’s absolutely possible.
How will we do it?
With good old email marketing.
"Wait a second—email? Isn't that a dead channel no one uses anymore? I don’t even read emails myself. I just delete them without a second thought."
Maybe YOU don’t read emails, but your customers do. Here are some stats you should know:
Acquiring a new customer is 5 to 25 times more expensive than retaining an existing one. (Source: Harvard Business School)
The average ROI for email marketing in e-commerce is 42:1 — meaning for every $1 invested, you get $42 back. (Source: DMA)
81% of online shoppers are more likely to make repeat purchases — whether online or in-store — based on personalized emails that reflect their shopping behavior and preferences. (Source: eMarketer)
Email marketing drives more conversions than any other channel, including social media and direct search, with an average conversion rate of 4.29%. (Source: Monetate)
49% of people said they’d like to receive promotional emails from their favorite brands weekly. (Source: Statista)
59% of respondents said marketing emails influence their purchase decisions. (Source: SaleCycle)
Here’s the kicker: with email marketing, you’re not dependent on anyone else. Not Meta, not Google, not TikTok — no one can take this channel away from you.
Your email list is yours.
You have complete control over your database.
(which is quite handy now that the big platforms are dishing out blocks left and right without any explanation – ask me how I know🤦♂️)
This means email marketing remains incredibly effective, especially in today’s world, where paid ads are getting more expensive, and customer acquisition costs keep climbing.
There’s never been a more critical time to focus on conversion rates and customer retention.
From my experience, I can confidently say that email marketing is still by far the most underrated tool in the e‑commerce game — which is fantastic news for you. It’s a golden opportunity to grab, giving you a chance to leave your competition in the dust.
Our results
We went all in on understanding how billion-dollar brands dominate email marketing—and how we could adapt those strategies for our clients at the 7- and low 8-figure levels.
The mission?
Build a solution that’s cost-effective, easy to manage, replicable, and scalable.
Big brands have resources, teams, and expertise our clients don’t—but that didn’t stop us from bridging the gap with a strategy built to win.
And it worked!
After diving deep into research and analysis, we distilled the most powerful email marketing techniques into a system tailored to our clients’ needs. The results speak for themselves:
Over 2,500 unique campaigns created.
More than 30.6 million emails sent.
Over $10,000,000 in revenue generated.
Our clients stick with us for 12+ months because the impact is impossible to ignore. It’s not just effective; it’s a game-changer for their businesses.
But don’t just take our word for it. Hear directly from the clients and partners who’ve experienced the impact of working with us:
Jan Pop
ex-CMO at FABINI
"I had the opportunity to work with Peter and RetentionUp for eight months after they took over email marketing at FABINI. Within just a few months, they transformed our basic transactional emails and manually sent newsletters into a sophisticated system of automated emails and top-notch campaigns that delivered significantly better results.
Thanks to Petr, email marketing quickly became one of our top sales channels, and RetentionUp became a key partner, helping us not only with email marketing but also with our overall marketing strategy.
What I appreciated most about Petr was his comprehensive thinking, proactive approach, reliability, and habit of going above and beyond expectations. If I were to choose a partner for email marketing again, I wouldn’t hesitate."

Oh my god, another agency…
"That sounds great, but I don’t want to work with another agency. I’ve had enough of them."
I get it. You’ve worked with agencies before and got burned.
Let’s be honest. Most agencies these days are essentially snake oil salesmen.
But you’re not alone. Our team consists of people who have owned or worked for real 7 and 8 figure e-com brands, so we’ve dealt with these kinds of agencies plenty of times ourselves. So, what sets us apart?
We get paid for results – No hourly rates or hidden fees. We have clearly defined deliverables (inputs) that consistently generate the desired results (outputs).
In other words: We don’t guarantee results. We guarantee building a proven system that will inevitably help you achieve those results.
We’re not a massive agency – We don’t have hundreds of clients, nor do we plan to. We’re a small team of passionate professionals who genuinely care about our clients. With us, you’ll feel like you have your own in-house team (but at a third of the cost).
Limited capacity – Since we don’t want to become a massive agency, we have limited capacity. Each month, we take on a maximum of 3 new clients, sometimes fewer. That’s because we want to deliver the best possible service and give you our full attention. That’s why we carefully select our clients and don’t work with just anyone.
From e-com brands, for e-com brands – Members of our team have worked internally for real 7 and 8 figure e-com brands. Thanks to this experience, we understand how they actually operate, what it takes to build them, and we share with you our experience regarding anything, not just email marketing.
To sum it up, we’re the complete opposite of a typical agency. The difference between us is like night and day.
If you’re looking for a big agency to handle all your marketing channels from A to Z, we’re not the right fit for you.
But if you’re looking for true email marketing specialists with real experience in building brands, you’re in the right place.
How does the partnership works?
“We already have email marketing in place…”
Let me guess:
A 10% discount on the first order.
A basic abandoned cart sequence with 1 or 2 reminders.
Mass campaigns about sales or new products sent to your entire list.
A bit of “personalization” by adding a first name to your subject lines.
Maybe some segmentation — grouping customers by purchase history or location.
Sound familiar? This is where most of our clients are when they start working with us. While it’s a decent start, it’s nowhere near unlocking the full potential of email marketing.
Here’s the truth: many agencies will sell you on flashy things like advanced segmentation, endless A/B testing of subject lines or send times, and all kinds of “sexy” tactics.
Why?
Because it sounds impressive and lets them charge you more – but in reality, these things rarely make a meaningful difference (again, ask me how I know).
The real key to success isn’t about chasing what’s “new”. It’s about nailing the fundamentals and doing them far better and more than anyone else.
So, what happens when you work with us?
Strategy tailored to you – We analyze your email marketing and create a strategy that focuses on doing the essentials at a higher level.
Building a strong foundation – We implement the five pillars of email marketing: database growth, automations, campaigns, deliverability, and optimization.
Focused improvement – Once the basics are in place, we refine, scale, and consistently execute to achieve maximum results.
Clear communication – You’ll get straightforward reports and full transparency into your email performance.
This is just a snapshot of what we do. Want to know more? Book a call with us and we’ll show you how mastering the fundamentals can transform your email marketing. 👇
Excited? Well there's a catch…
Woah, woah, woah — I understand you’re excited and ready to start, but there’s something we need to discuss first.
As I mentioned earlier, due to our company philosophy and small, dedicated team, we can’t (and don’t want to) work with just anyone who reaches out. We are extremely selective about who we choose to partner up with.
We’re not looking for short‑term collaborations but rather long‑term partnerships where we can help build an incredible brand that we can all be proud of.
Here are the three most important criteria our ideal client needs to meet:
A brand with vision – We don’t work with dropshipping stores or other e‑commerce businesses that simply resell products from cheap suppliers with the sole aim of making a quick buck, without caring about customers or the broader impact. We want to partner with brands that have a clear vision and mission. Brands with products that people genuinely love and that improve their lives.
Paid advertising – We only work with brands that regularly invest in paid advertising. Without traffic, even the best email strategy won’t work. If you’re not investing in paid ads, we won’t be able to help you just yet.
Monthly revenue above $150k/month – For one important reason: if you’re still searching for product‑market fit or haven’t successfully scaled paid ads, your focus should be there first. Without traffic, email marketing will be an uphill battle.
If this opportunity resonates with you and you meet these three criteria, click the button below to schedule a call and let's take your brand to the next level. 🙂
PS: Still not fully convinced?
Alright, challenge accepted. Let’s break down your options:
Do nothing – You can ignore this offer and stick with what you’ve been doing. Sure, you’ll save some money upfront, but you’ll potentially leave millions on the table every year. Just remember, doing nothing has its own cost.
Hire a big-name agency – They’ll promise you the moon and stars. When you have a new product or sale, they’ll blast a generic email to your entire database, generate some sales, and report back with “amazing results” you probably could have achieved on your own. Meanwhile, you’ll be pulling your hair out over their lack of communication and transparency. Oh, and don’t forget the hefty invoice for “25 hours of work” plus upsells for additional services you apparently must have to succeed.
Build your own full-time team – You could hire a dedicated email marketing team, but they’ll need training to get up to speed. You’ll spend countless hours onboarding them or paying for expensive courses to teach them theory. Even then, you’ll likely underutilize their potential and overpay for mediocre results.
Work with us – Click the button below and partner up with seasoned email marketing experts who’ve generated over $10,000,000 for their clients purely through email. We know what it takes to build a brand that customers truly love, and we genuinely care about your success.
With us, you’re not just another client — we’ll treat you like a true partner. You’ll feel like you have your own in-house email team, but at a third of the cost. Together, we’ll create something exceptional.
The decision is yours. We’re ready when you are. 🙏

Founder of RetentionUp
