Klaviyo flows for the Polish market: transferred, checked, launched
For a supplement brand with several million euros in monthly revenue, we set up email marketing in Klaviyo for Poland for the launch of the Polish store in autumn 2026: consent, flows, forms and a clean separation of languages.

A mature German setup that needed to run just as smoothly in Poland.
The brand already had a mature Klaviyo setup for the German market. For the Polish launch, the relevant flows needed to be properly localised and set up in a separate Polish structure.
The brief was clear: adopt what exists, don’t reinvent it. The work was in the details. Links had to point to Polish pages, discounts had to work in złoty, graphics contained German text, and for some customer profiles the language was not clear.
We transfer, build and check. Design and approvals come from the brand.
An honest split: what we do ourselves and what others contribute.
Our part
Transfer, technology, checks
- Inventory of the German flows and templates
- Localisation from German to Polish: subject line, preview text, copy, buttons, alt texts and footer
- Polish list, consent pages and forms
- Language assignment and switchover of the flows
- Design briefings and integration of the delivered graphics
- Quality control, tests and activation after approval
The email design and all graphics come from the brand’s team. Our part is the transfer, the technology behind it and the checks.

What is running for Poland today.
Status according to the project documentation, autumn 2026.
Consent in Polish
Live- A separate Polish newsletter list
- Sign-up, confirmation, double opt-in, preference and unsubscribe pages
- Programmed pages extended with Polish without changing the other languages
Forms in the store
Live- Newsletter section in the Polish store connected to the Polish list
- Pop-ups for desktop and mobile based on existing templates
- Sign-up, double opt-in, first welcome email and unsubscribe tested successfully
Links and discounts
Checked- Links in the emails switched to Polish targets
- Discount codes checked in złoty in test carts, without a real order
Transactional emails
LiveOrder and shipping confirmations were requested and approved as transactional in Klaviyo. That way they also reach customers without newsletter consent.
More flows
PreparedMore flows are prepared as drafts and only go live after the checks and the brand’s approval.
Where care mattered.
Language is not the same as country
Who gets Polish emails? The answer was less clear-cut than it sounds.
Problem
Some customer profiles had conflicting data on language, store language and country. If assigned wrongly, someone signing up in Polish would have received German emails, or both.
Decision
Only clearly Polish profiles enter the Polish flows. Conflicting profiles are blocked instead of guessed.
Solution
Fixed assignment rules, exclusion of Polish profiles from the German flows and test cases run through before launch.
Status
Live since autumn 2026.
| Profile | Example | Result |
|---|---|---|
| Clearly Polish | Language, store language and country match Poland | Polish flows, excluded from the German ones |
| Clearly German | All data matches Germany | German flows as before |
| Conflicting | Data does not match up | Blocked instead of guessed |
Switching between language versions in a controlled way
German and Polish flows had to hand over cleanly during live operation.
Problem
During the switch, nobody may slip through and nobody may receive emails twice.
Decision
A fixed order for each flow pair: first activate the Polish flow, then restrict the German one.
Solution
A documented process with a way back. We openly named a short possible overlap window instead of keeping quiet about it.
Status
All flow pairs switched over in autumn 2026.
Clean handovers and fixed checks before every go-live.

What is running and what we don’t claim.
What we don’t claim
We don’t state open, click or revenue figures for Poland here. The channel has only been running since autumn 2026. We will only share figures once they are meaningful and approved by the brand.
What’s next
More flows are prepared as drafts. Before go-live, the remaining functional checks and the brand’s approval will follow.
