Email marketing and Shopify for D2C brands

Klaviyo and Shopify under one roof.

We build Klaviyo flows and campaigns and, if you want, your entire Shopify store as well, from migration to a custom theme. For D2C brands from €50,000 in monthly revenue.

Most stores burn money on new customers and forget the ones who have already bought.

01 / 03

Rising costs

Ad costs are rising. Margins are shrinking. And still the entire budget goes into ads.

02 / 03

Untapped potential

Email marketing reaches people who already know your brand. Without the right flows and segments, that potential goes unused.

03 / 03

Put off

A newsletter every two weeks isn't enough. A Welcome Flow from 2019 isn't enough.

Real growth lies with the customers you already have.

Three services. Individually or all from one team.

We take care of your email marketing in Klaviyo, build your Shopify store and look after both on an ongoing basis if you want. Behind every service is a real project.

01Email

Klaviyo support

Setup, flows and campaigns that run around the clock, with solid deliverability and consent.

  • Flows from welcome to winback
  • Segmented campaigns instead of mass emails
  • Deliverability with SPF, DKIM and DMARC
  • WhatsApp alongside email

Proof: SHEKO, 50 Polish emails live in six flows

02Shopify

Shopify migration and custom theme

We move your store to Shopify, for example from WooCommerce, and build a theme that fits your brand.

  • Data transfer and redirects for old URLs
  • A custom theme instead of a template
  • Several languages, readable by Google
  • Klaviyo connected straight away

Proof: ZinCuTec, 215 redirects, store in five languages

Shopify management with email marketing

We look after your whole store and your email marketing on an ongoing basis. One contact instead of several providers.

  • All processes and changes in the store
  • All your email marketing in Klaviyo
  • Checks before every release
  • No minimum term

Proof: ZinCuTec, ongoing support since August 2025

Real projects instead of big promises.

Two ongoing client projects. They show what we deliver: email and retention marketing in Klaviyo, Shopify development and fixed checks before every go-live.

From WooCommerce to Shopify: a custom theme in five languages

For a metalwork manufacturer from Nürtingen, we moved the store from WooCommerce to Shopify, developed a custom theme and took it live in five languages. Larger changes were accompanied by page comparisons and documented checks. Plus the complete email marketing in Klaviyo. We have looked after the store and Klaviyo on an ongoing basis since August 2025.

Klaviyo flows for the Polish market: transferred, checked and switched live

For the launch of the Polish store, we rebuilt the German Klaviyo setup for Poland: consent, flows, forms and a clean separation of languages. Design and graphics come from SHEKO.

  • 6Flows localised
  • 50Emails live
  • 244Links updated

As of October 2026. The size reduction at ZinCuTec refers to stored theme files including unused media, not to loading time. We only state what we can back up. We only publish revenue or conversion figures once they are meaningful and the client agrees.

No account manager who just passes things on. A founder who works in the account himself.

At many agencies, your request ends up with someone who passes it on. With us, founder Szymon Wolowicz works in your Klaviyo and Shopify accounts himself.

01

Founder in your account

No middleman between you and the work. Less back and forth, faster results day to day and someone who really understands your business.

02

Both sides of e‑commerce

Szymon ran his own online shop and then worked at three email and retention marketing agencies: ondevi, MAILODY and Retention Only, most recently leading projects and teams. There, he also looked after accounts that turn over several million euros a month. We know the day-to-day reality of running a store and the craft of working in Klaviyo.

03

Check instead of hope

Depending on the change, we check links, mobile display and deliverability rules before go-live. You get clear reports instead of gut feeling.

Three steps to email marketing that grows with you.

No complicated onboarding and no upfront work from you. We reply to messages within 24 hours.

01

Book a call

Pick a 30-minute slot for the free audit. You don't need any preparation or account access for it.

02

Take a look together

On the call, we look at your setup and your goals. Not a sales pitch, but an honest assessment.

03

Audit and quote

Within a few days, you get concrete recommendations. If it's a good fit, we get started with a fixed scope.

Honest answers before you ask.

The questions we are asked most often before working together.

It depends on the scope: a one-off setup is priced differently from ongoing support. After the free audit, you get a fixed quote with a clear scope and no hidden costs.

No. We want you to stay because working together pays off, not because of a contract.

No. You don't need to prepare anything for the first call. You only give us access once you want an in-depth audit or to work together, and then with a separate user that you can remove at any time.

Directly. Founder Szymon Wolowicz is your point of contact and works in your account himself.

For Shopify stores with their own brand in the DACH region, from roughly €50,000 in monthly revenue, that want to take email marketing seriously. If you're smaller, tell us anyway: in the audit, we'll tell you honestly whether working together is worth it yet.

Yes. We start with an honest look at your existing setup and show you what's working well and where revenue is being left on the table. Whether you change anything afterwards is up to you.

Yes, end to end. We migrate stores to Shopify, for example from WooCommerce, develop custom themes, set up multiple languages, connect everything cleanly to Klaviyo and look after the store on an ongoing basis if you want. One example is our ZinCuTec project.

Klaviyo integrates natively with Shopify and has segments, flows and reporting in one place. If you use a different tool, we'll take a look at it and help with the migration if needed.

It depends on where you're starting from. Core flows such as Welcome, Cart Abandonment and Post Purchase can go live early and collect data from then on. How much revenue they bring in depends on traffic, list size and product range. We tell you up front what's realistic and then measure it together with you in Klaviyo. We don't promise fixed timelines for results.

Direct and straightforward: regular updates, clear reports and a dedicated point of contact who knows your business. No ticket system.
