Questions before you buy
- What is inside the file?
- Company name, registry code, legal form, activity, address and region, plus email and phone where available. You see the exact columns in the free sample.
- How fast do I get the data?
- Immediately after payment. The download link is emailed to you and works from any device for a limited time.
- Is buying and using this data legal?
- Yes, for business-to-business use. The data comes from public Estonian registry sources, we sell B2B contacts only, and you must identify yourself and honour opt-outs in your own outreach.
- Can I get a custom selection instead of a whole database?
- Yes. Build your own list with filters for sector, region, legal form, size and contact type — you see the live count and price before you pay.
- Does the free sample include real contact details?
- Yes. The sample contains 25 real companies matching your filters, with the same columns as the paid file — including email and phone where they exist.
- How fresh and accurate is the data?
- Records are compiled from official public Estonian business sources and refreshed continuously. Contact details exist for most, but not every, company — the sample shows the real fill rate before you pay.
- What if the data does not match what I expected?
- Check the free sample first — it is the same data as the paid file. If a purchased file is clearly faulty, write to us and we will fix or refund it.
- I have the list. What now?
- Either send the campaign yourself or let us do it: we plan, write, design, send and report on your B2B email campaign to Estonian companies.
