You work hard to bring
customers in. Email should keep them.

Every customer who leaves, you paid to acquire. Then you pay again to replace them. We build the email and SMS flows that bring them back instead, tuned for DTC brands on Shopify. Fix retention, and acquisition finally starts to compound.

What email actually does

Email is how a brand
turns a buyer into a regular.

Acquisition gets a customer in the door once. Email is how you earn the second order, and the tenth. A nurtured customer list is one of the most valuable assets a brand can own right now. Here's the journey we build to grow it.

Three gaps that quietly
cost you customers every month.

These aren't edge cases. They show up at brands doing $1M and brands doing $10M. Fixing them is usually worth more than your next month of ad spend.

They came in with high churn, no win-back flows, and acquisition costs eating into margin because customers weren't coming back. An extensive post-purchase flow and an educational campaign series built habit before customers ever thought about leaving. Churn dropped from 15% to 9%. LTV climbed. That freed-up margin went back into acquisition. That's how 30 active customers became 300 in twelve months.

A note from our founder

I tried to build
one of these brands.

Kei Nakayama Kei Nakayama
Founder, hanjo

A few years ago, I tried to start a pre-made meal-kit brand in Japan. I got far enough to understand what it actually takes. The sourcing, the packaging, the logistics, the relentless problem-solving before a single order ships. I couldn't build a product I was proud enough to sell.

That experience changed how I see the people I work with. The founders who do make it, who find something worth coming back to, build a brand around it, and keep showing up, have my lasting respect.

What we do now at hanjo is a different kind of problem. Once a brand has a great product, the work becomes keeping the people who find it. That's where most email setups quietly fall apart. Not because the brand isn't good enough. Because the email infrastructure wasn't built to support how returning customers actually behave.

Most of the brands we work with have roots in Japan: the product, the founder, or the customer base. These brands often carry a distinct kind of customer relationship: high trust expectations, a more deliberate repurchase rhythm, a preference for depth over noise. Generic email setups don't account for that. We build ones that do.

We work with founders who have already done the hard part. Our job is to make sure their retention side is working as hard as they are.
