Your in-house team may already do strong work, but you need more senior expertise or execution capacity. Or the agencies, freelancers, or consultants you’ve tried haven’t quite nailed your brand voice, design, or product details.
Flow projects stay “in progress,” and revenue still depends too heavily on promotions. Pull back on discounts and open rates might hold, but clicks, conversions, and sales drop. You need senior retention experts in your corner who can move quickly, protect your brand, and drive measurable revenue and profit growth year after year.
That’s where we come in. We’ll build and run 5 Backend Profit Systems™ to turn more traffic into customers and more customers into repeat buyers, so you can scale profitably.
Flows, campaigns, popups, and SMS. Every design built and run by our team. Tap any to open the full thing.

Collection drop+We identify where attention stops turning into purchases, then improve the message, offer, targeting, and path to purchase.
We build your 0 → 1 Purchase System with signup offers, relevant product education, and pre-purchase follow-up.
Your 1 → 2 → 3 Purchase System connects product education, replenishment, complementary products, and subscriptions to encourage the next purchase.
We give customers reasons to buy between promotions through customer stories, product education, launches, and coordinated campaigns.
Together, we decide which work we own and where we support your people, with clear responsibilities and agreed capacity across your retention stack.
I'm Zach, and I started ZHS Ecom after studying statistics and machine learning at Carnegie Mellon, where I learned to treat everything as a system you can measure and improve. That's exactly how our team approaches your email and SMS.
Over the past six years, we've driven more than $50 million in attributed revenue for over fifty DTC brands, and the average one has stayed with us well past a year and a half. That kind of retention only happens when the work is genuinely good and the relationship is genuinely close.
So think of us as the retention team you don't have to hire. We keep the roster deliberately small, which means the people on your account are senior operators who know your business, your voice, and your numbers, instead of junior staff you get passed between.
We start with your traffic, customer base, margins, and current email/SMS performance. Your free audit identifies the gaps and opportunities, and your 90-day gameplan shows how we would address them.
The potential and timeline depend on your starting point. We’ll explain what needs improving, what we recommend doing first, and the expected impact before you decide to work with us. You can also explore our client results to see the work behind the numbers.
With ZHS, strategy, offers, copy, design, technical execution, and reporting sit with one senior retention team. We take responsibility for getting the work live, testing it, and improving the program over time.
When comparing options, look at who will own each part of that work and how much management your team will need to provide. We bring those capabilities together and work alongside your existing people, freeing them to spend more time on the rest of the business.
We start by learning your products, customers, brand voice, and design guidelines. Early creative examples help us get aligned before we build out the wider program.
You review the copy and designs before they go live, and we handle revisions based on your feedback. That gives you control over how your brand shows up without having to write and design everything yourself. Our client email designs show how that work adapts across brands.
We can own strategy and execution, guide your internal team, or combine both. Before work begins, we agree who handles offer planning, copy, design, builds, testing, and reporting. Your team provides brand context, access, feedback, and approvals.
The copy, designs, and automations we build are yours to keep.
Yes. We’re platform agnostic, with experience across tools including Klaviyo, Shopify, Postscript, Attentive, WooCommerce, and BigCommerce.
We review your existing platforms, integrations, and customer data, then build the plan around your business. If a tool needs replacing or an integration needs additional work, we’ll explain the recommendation and scope before you commit.
Engagements start at $15K/quarter or $6K/mo. Every partnership is custom-scoped around your opportunities, program complexity, channels, markets, and the responsibilities shared between our teams. We agree on scope, investment, and terms before you commit.
We offer 2 guarantees:
A. Initial direction guarantee. After paid onboarding, you review the flow gameplans, campaign calendars, and showcase templates included in your agreed scope. If the direction isn’t right at that checkpoint, you can cancel and receive a full refund of your initial payment before the remaining work begins.
B. 10X revenue guarantee. For qualifying engagements, we guarantee 10X our fees in net-new revenue over the agreed measurement period. If we fall short, we refund fees in proportion to the shortfall.
We agree on eligibility, review checkpoints, and measurement terms before you commit.
Book a Partnership Exploration Call so we can learn about your brand, current email/SMS setup, and growth goals.
If we’re a fit, we’ll audit your account and walk you through a 90-day gameplan on a second call. Whether we work together or not, you’ll leave with the audit and gameplan.
