Full-stack retention marketing for e-commerce
Not an email agency. Your retention growth partner.
The 80% that happens after ads, run & optimized by one lean team.
Not a copy-paste email agency. Not an overseas freelancer. Pareto is a lean team of seasoned retention experts growing brands choose when they know they're leaving LTV on the table but aren't ready to hire in-house (or sign another letdown agency). We run everything downstream from ads: acquisition offers, subscriber growth, email, SMS, onsite chat, referral, loyalty, review gen, even CRO. And we take on all the risk up-front, so you don't have to.
0% client churn since 2022 · 2X ROI guaranteed in 90 days · Month-to-month, no contracts
What we do
Email is the easy part.
Most agencies stop at email. We treat it as the foundation, and across our roster, email alone drives north of 40% of total revenue. Then we build everything around it: SMS, on-site chat, acquisition, and social-to-lifecycle conversion. One lean, AI-powered team running your entire retention engine, so your existing customers become your biggest, most predictable growth lever.
Email Marketing
Where most brands leave money on the table, and where we start. Flows, campaigns, segmentation, and creative built to convert. Across our roster, email alone drives 40%+ of total revenue.
SMS Flows & Campaigns
We build or rebuild your SMS program from the ground up. Across the roster, SMS adds another 15–20% of total revenue, added on top of email, not taken from it.
On-Site Chat Experiences
From customer-service automation to on-site chat campaigns that drive education and conversion at the exact moments that matter in the buyer's journey.
Customer Acquisition & Retention
An elite retention program only works if it's constantly fed. We test acquisition offers through high-converting popups, forms, landing pages, and social flows that lower your cost to acquire and flood your list with red-hot leads, then build the flows that keep them.
Social-to-Lifecycle Conversion
Convert your organic social audience into email and SMS subscribers with custom Klaviyo × Meta flows. No link clicks, site visits, or arm-twisting, simple reply-to flows that turn followers into subscribers at zero cost.
Plus everything around it
The standout offer
Two free emails + your pop-up. On us.
To prove email is just a warm-up for us, we'll build or optimize your current welcome pop-up and deliver two ready-to-send emails, completely free. If they work and we're a fit, great: your first month of service was earned by us before you spent a penny. If they don't… we wouldn't know. That's never happened.
- We build or optimize your welcome pop-up
- Two complete, ready-to-send emails, yours to keep
- 100% free, before you ever pay us a cent
If you don't see at least a 2X return on your total investment in 90 days, we'll work for free until it's returned.
Why we're different
The incentives are built to match yours.
Most brands are stuck choosing between an in-house team they can't justify yet, an overseas freelancer who ghosts, and an agency that runs one playbook on everyone. Pareto is the fourth option: a lean team of seasoned retention experts that earns its keep every month, with the risk on us, not you.
A real team, not a template
Strategy, copy, design, build, and data: the retention team you'd hire in-house, minus the hiring. No freelancer roulette, no copy-paste playbook.
2X ROI in 90 days, guaranteed
If you don't see at least a 2X return on your total investment within 90 days, we work for free until it's returned.
Free to start
We build your welcome popup and welcome flow upfront at no cost, so you see real work before any commitment.
Month-to-month
No long contracts, no lock-in. We re-earn your business every single month by performing.
0% churn since 2022
Every client who's started with us has stayed. One partner turned down 50+ agencies to keep working with us.
AI-driven & lean
One lean, AI-powered team replaces an in-house email, design, copy, and data hire, faster and cheaper than a legacy agency.
The results
Real brands. Real revenue. Held for years.
We don't chase one good month. Every result below is a run rate our partners have sustained, verified by Klaviyo placed-order attribution from each client's own account. Brands anonymized.
20× monthly lifecycle revenue in 24 months, from email under $80K/mo to $1.55M/mo across email + SMS, with the SMS program built from zero. 48% of total revenue is now lifecycle-driven.
3× monthly lifecycle revenue. We built their entire lifecycle channel from the ground up, integrating SMS and flows by year two. 60% of total revenue is now lifecycle-driven.
5.2× email revenue growth. The CEO owns three brands and trusts us to run all three, and turned down 50+ agencies to stay with us.
In their words
What our partners say.
“We started with Pareto in 2024 after a miserable agency experience. We were skeptical but optimistic about the growth-partner concept. When we started, we were doing ~$70k/mo on Klaviyo, no SMS or other retention channels. Keaton and his team took over email, optimized our acquisition offer, launched SMS, loyalty & referral, onsite chat, and took us to our first $1 million month from lifecycle in 8 months. They've consulted on ads, built landing pages, and even helped optimize our product pages and checkout experience. Our lifecycle ecosystem now grosses some $1.5M+ per month, roughly 55% of our total brand revenue. We wouldn't be where we are without Pareto, they truly are the partner they promised they'd be.”
“We've been with Keaton & Pareto for 4 years, from some $200k a month to now $1.3M+. They also helped launch and still manage all 3 of our brands, so they drive north of $2M a month. I've been pitched by countless other agencies and I just won't work with anyone else. They're a true partner in our growth, there when we need them, and they go way beyond email. As a CBD brand we've struggled with ads and even legislation, and there's just no way we'd be where we are without them. Also just great to work with, we have fun on our calls, strategy to execution is smooth, they have genius ideas, copy is on point, and lifecycle overall is crushing, usually 45% or more of our revenue across all 3 brands. Couldn't recommend them highly enough.”
“Where do I start… I've worked with Keaton and his team at Pareto for 3 years now (maybe 4?). They started as our agency for just email, then recently took on more of a growth-partner role in our business and things are really starting to take off, email, SMS, our Gorgias chat system, and now consulting on ads and building landing pages/new offers. With everything they manage, they drive some 65% of brand revenue. They introduced the idea of multi-packs for us and that's completely changed our business. Wouldn't bother with another agency, they're just phenomenal. We'll be partners until I sell and retire.”
“We've loved working with Keaton. He keeps things fun, yet professional, and has grown our email & SMS channels by some 2x. Also introduced us to Gorgias and helped build that out, which has totally reshaped our customer service and site experience. He's very attentive to our needs as a brand and has always worked fast to make things happen when we need it. I would recommend him… but you can't have him!”
“Keaton is the man! We've been working together for 3 years now. Email and SMS bring in more than half of our revenue, and we cut our agency bill almost in half. I like that our marketing is fun, yet effective and consistent. Keaton makes it easy, definitely recommend him.”
“Working with Keaton has been great! We love that he keeps things simple and focused on driving us toward our big-picture goals. Email is now 35%+ of our revenue, better than it's ever been. Wish I would've found him earlier…”
