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.

Everything your email marketing needs. Under one roof.

From strategy to execution to optimisation. We take care of your entire email & retention marketing and, if you want, your Shopify store too.

01

Email Marketing

The most important channel in your CRM setup. We develop a strategy that turns one-time buyers into loyal repeat customers.

02

Automations & Flows

Welcome, Abandoned Cart, Post Purchase, Winback and more. Flows that generate revenue around the clock. Even while you sleep.

03

Campaigns & Content

No mass emails to your entire list. Segmented campaigns with content your customers open, read and click.

04

Klaviyo Setup & Migration

Not on Klaviyo yet? We'll migrate you. Already on Klaviyo? We'll optimise your existing setup for maximum performance.

05

WhatsApp Marketing

A direct channel for abandoned carts, shipping updates and VIP offers. Built as a complement to email, with consent and without annoying your customers.

06

Deliverability

We check authentication, list quality and sending behaviour to spot deliverability issues and improve the chances of landing in the inbox.

We build the store too. Tailored to your brand.

Email marketing only works as well as the store behind it. That's why we also take on Shopify if you want: from migration to a custom theme to the Klaviyo integration.

01

Migration to Shopify

We move your store to Shopify, for example from WooCommerce. We redirect old URLs so that visitors and Google don't hit dead ends.

02

A custom theme instead of a template

We develop your Shopify theme to fit your brand and your store's requirements. Your team still manages products and copy itself in the admin.

03

Multilingual and readable for Google

Multiple languages in one store, each with its own URLs and hreflang. Headings, copy and FAQs sit directly in the HTML so that Google can read them.

04

Store and Klaviyo under one roof

Forms, sign-ups and purchase data flow cleanly into Klaviyo. Because the store and the email marketing both come from us, they fit together.

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.

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. 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 and connect everything cleanly to Klaviyo. 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.
