For DTC Brands Doing $1M+/year

We turn Email + SMS into your highest-margin revenue channel

If Email + SMS isn't driving 20-40% of your total store revenue, you're leaving profit on the table. We run retention from start to finish: strategy, copy, design, builds, campaigns, and weekly optimization. So your existing traffic buys more, more often.

You're not buying "email marketing"

You're buying outcomes. Here's what that actually means.

Channel Ownership

You don't manage it. You don't coordinate it. You don't have to be the glue. We own the entire retention channel so you can focus on running your business.

Speed to Signal

You want proof it works fast, not perfection later. We get flows live quickly, show you early wins, then optimize from there. Results before polish.

Accountability

One throat to choke. Clear KPIs. Merit-based continuation. If we don't perform, you leave. No contracts, no excuses, no finger-pointing.

Systems Thinking

We see the full picture: acquisition → capture → activation → revenue → reporting. Not just emails in isolation, but how retention fits your entire business.

Every retention asset you need, built by our team of specialists. Automated flows that work 24/7, scheduled campaigns, and list growth tools.

Flows are automated email sequences triggered by customer behavior. Build them once, and they work 24/7 forever. Think welcome emails, cart abandonment, post-purchase follow-ups. This is a one-time investment that generates recurring revenue.

Campaigns are scheduled emails sent to your list on specific dates. Flash sales, product launches, newsletters, seasonal promotions. These are your monthly promotional sends that keep customers engaged and drive consistent revenue.

Popups capture emails and grow your list. Convert visitors into subscribers with strategic timing and compelling offers. These tools build your audience at critical moments in the customer journey.

SMS/WhatsApp reaches customers with high-urgency messages. 98% open rates and instant delivery make text messages perfect for time-sensitive offers, order updates, and direct communication with your best customers.

ZHS Ecom Team

Built to be your in-house team

Most agencies spread themselves thin. We keep our client roster small so each brand gets real attention. Your account manager knows your business, your designer knows your brand, your copywriter knows your voice.

We remember your feedback. We learn your preferences. We improve over time. That's why our average client stays 1.5+ years. We're not an external vendor you have to manage. We're the retention team you don't have to hire.

10+ Team Members 50+ DTC Brands Served 1.5+ Year Avg. Retention Senior Talent Only

Why work with us?

We're selective about who we work with, and we expect the same from you.

ZHS Ecom Other Agencies
Long-term partners focused on outcomes Just focus on deliverables, not results
Few clients, go deep on each one Stretched thin across too many accounts
Remember your feedback, improve over time Forget nuances, make same mistakes twice
Proactive with ideas, push back when needed Reactive, just waiting for instructions
Clear metrics, actionable reporting Vanity metrics that don't tie to revenue

Good Fit

  • Already successful, want to take things to the next level
  • Value quality and premium execution over cheap and fast
  • Looking for a long-term partnership, not a one-off project
  • Want a team who's seen the insides of 7-8 figure accounts
  • Open to us pushing back and bringing fresh ideas
  • Care about business success, not just Klaviyo metrics

Not a Fit

  • Prioritize cheap cost over quality
  • On a shoestring budget with no room to invest
  • Looking for quick hacks or band-aid fixes
  • Just want the cheapest person to build some emails
  • Want a "yes man" who agrees with everything
  • Need results in 2 weeks with no room for proper strategy

Frequently asked questions

Everything you need to know about working with us.

Our clients typically see a 10-35% lift in overall revenue from retention marketing within 90 days. For established email programs, this channel often accounts for 20-30% of total store revenue. Your results depend on your current setup, list size, and product margins. We provide personalized projections during our strategy call.
We charge a transparent per-email fee, not a percentage of your email revenue. This means we're incentivized to make every email count. There's no benefit to us sending more emails than you need. As your email revenue grows, the ROI on each email increases while your costs stay predictable.
Yes! For brands under $1M/year, we recommend our Core Foundation Flow Build-Out. It's a one-time build that covers everything you need to get your email marketing engine running: welcome series, abandoned cart, post-purchase, browse abandonment, and more. We can also add 8 email campaigns per month to keep your list engaged and driving revenue while you scale.
Both, and we recommend starting with Flows. Flows are automated sequences that run 24/7 once live. Think of them as salespeople who never sleep. After your flows are generating revenue, you can add Campaigns for promotional sends. Each email includes strategy, design, copywriting, A/B testing, and SMS/WhatsApp variants. We also handle resends to non-openers at no extra cost.
You'll see results in two phases: Quick wins (14 days) with improved email metrics, and substantial revenue impact (60-90 days) as flows are built and campaigns optimize. We typically have you on our first strategy call within 3 days, first assets for review in 7-10 days, and campaigns launching in 2-3 weeks.
No contracts. Month-to-month flexibility. You can pause or change your plan anytime. That said, we recommend a minimum 3-month engagement to see meaningful results. Most clients stick with us because of the revenue impact, not because they're locked in.
You own everything. Your Klaviyo/Shopify account, your email list, all campaigns and flows we build. It's all yours. We're partners managing your email channel, not a platform you depend on. If we part ways, all your assets and data leave with you.
About 45 minutes per week. You review emails before we send them, provide feedback, and we incorporate updates. We handle all the strategy, design, copy, testing, and optimization. The goal is to add revenue without adding stress to your team.
We work alongside your existing team, not against them. Many clients have a marketing manager who handles approvals while we do the heavy lifting. We can also fully replace an underperforming agency or freelancer. Either way, we integrate into your workflow and make whoever's involved look good.
We offer unlimited revisions on copy and design until you're satisfied. If after 30 days you're genuinely unhappy with our direction or approach, we'll part ways on good terms. Your success and satisfaction are non-negotiable.
