But you haven’t found the right operators to take ownership. Your in-house team is stretched, while 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 Email/SMS Systems™ to help you turn more of your traffic into customers and more of those customers into repeat buyers, so you can scale profitably.

"10 out of 10. A lot of massive firms charge you an arm and a leg and you don't get the same communication or results. Every time I email, you're back within an hour, even on a Friday night. Within a month I knew this would be a long-term partnership."
Watch Jack's interview"I could not do 5% of what you guys accomplished, and it would have taken me two years. We did it in about three weeks. If you're on the fence about doing it yourself, go with the experts. You'll be in really good hands."
Watch Alexa's interview"An absolute great group of guys who know a lot about email and how to make more money on the back end with your list. Super responsive. We needed emails out on a Saturday morning and they were there for us. His team is bar none."

Collection drop+Our 5 Backend Profit Email/SMS Systems™ turn more of your existing traffic into subscribers, buyers, and repeat customers. We put offer strategy to work across signups, campaigns, flows, repeat purchases, and subscriptions, with one team accountable for execution and results.
Weak signup offers and easy-to-ignore forms let interested shoppers leave without subscribing.
Bring interested shoppers back to buy through email and SMS, without paying for another ad click to reach them.
Close the gaps between campaign sends with offers and automated follow-up that give interested shoppers a reason to act.
Generate sales today and keep converting interested shoppers between campaigns, without making your team chase each opportunity.
Sending everyone the same pitch ignores where they are in the buying journey.
Increase sales per send by matching the message and offer to the buyer and the moment.
Repeated discounts can train customers to wait for the next sale, eroding margins and weakening full-price demand.
Earn more from each customer while protecting your margins and giving them reasons to choose your brand at full price.
When nobody owns the whole program, you spend your day coordinating people, chasing deliverables, and getting tools to work together.
Reclaim time for the highest-value work in your business, with one team accountable for execution, follow-through, and results.
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 handle the email/SMS strategy, offer planning, copy, design, builds, testing, and reporting within the scope we agree together. Your team provides brand assets, product and business context, access, feedback, and approvals.
We review your existing program and agree on responsibilities before taking over the work, including how we’ll collaborate with your current team. 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.
Initial engagements typically range from the mid-four to low-five figures and run for 30–90 days. The scope, investment, and timeline depend on your brand, your current setup, and what you want to achieve.
We’ll recommend a starting point based on your audit and talk through the initial scope and any longer-term options before you commit.
For qualifying engagements, we guarantee 10X our fees in net-new revenue. If we fall short of the agreed target, we’ll refund our fees in proportion to the shortfall.
We’ll explain how the guarantee applies to your engagement before you commit.
Book a short discovery call so we can learn about your brand, current email/SMS setup, and growth goals.
From there, 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.
