Results we've delivered

Here's what happens when one team actually owns your retention.

View All Case Studies

Most brands outsource email and SMS, then wonder why it looks generic and barely sells.

It's always the same problem.

Whoever they hand it to never really owns the brand.

In-house

Full salaries for one point of view that only sees your brand.

Cheap agencies

Templated sends, one team across a dozen accounts. Nobody goes deep.

Generic AI

Low-converting emails in a voice that's nothing like yours.

With ZHS, four senior specialists own your results end to end. Fewer brands, so we go deep.

Here's what we build.

Flows, campaigns, popups, and SMS. Every design built and run by our team. Tap any to open the full thing.

Why ZHS Ecom
Fewer brands.
All in on each.
Pods of 4

Four senior people on your brand. As close to in-house as you can get without hiring.

10-20x ROI or we pass

We only take brands where we can realistically return at least 10-20x. If the math doesn't work, we tell you.

We stay

Long-term partners who know your voice, your products, and your numbers cold.

Best, not cheapest

We track revenue, not open rates. Every move ties back to your bottom line.

Right fit. Established DTC brands that want the best and will invest to get it.
Not a fit. Anyone shopping for the cheapest email they can find.
Zach Schieffer, Founder of ZHS Ecom
A note from our founder

Why I built ZHS Ecom

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.

Frequently asked questions

What happens after I sign?
We scope a custom plan, send the contract and invoice, and you fill out a short onboarding form on your brand, products, voice, and offers. From there we align on a kickoff call, add you to Slack, and start building. Early on, three showcase templates lock in your design and voice for every flow and campaign after.
How fast can we see results?
Quick wins on deliverability and early sends land in about 14 days, with meaningful revenue impact in 60 to 90 days as your flows go live and campaigns start to optimize.
What's included: flows, campaigns, or both?
Both. We usually start with flows since they run 24/7 once live, then layer in campaigns. Every send includes strategy, copy, design, A/B testing, and SMS, with resends to non-openers at no extra cost.
How much time do I need to invest?
About 45 minutes a week to review and approve. We handle the strategy, copy, design, testing, and optimization from there.
Do you work with brands under $1M a year?
Yes. We start you with a one-time flow build (welcome, abandoned cart, post-purchase, browse abandonment, and more), then add quarterly campaigns to keep your list driving revenue as you scale.
How does pricing and commitment work?
No long-term contract. Flows are one-time projects that are yours to keep once we build them, and campaigns run on a quarterly basis. We suggest giving it at least three months to compound, but you stay for the results, not a lock-in.
What if I'm not happy with the work?
You get unlimited revisions on copy and design until you're happy, and if you're genuinely not satisfied after 30 days, we part ways on good terms.
