Question 1

Is it legal to buy a B2B email list in Belgium under GDPR?

Accepted Answer

Yes — B2B email lists for direct marketing to legal entities are permitted under GDPR and the Belgian Data Protection Act, provided you can demonstrate a legitimate interest and offer a clear opt-out in every message. Our lists are restricted to business email addresses at registered legal entities and exclude sole proprietors by default to stay within the B2B exemption.

Question 2

Where does the Belgian company data come from?

Accepted Answer

Records are sourced from the KBO/BCE (Crossroads Bank for Enterprises) — the official Belgium business register — and enriched with verified email contacts collected from public corporate sources. New registrations are pulled in monthly, and email validity is re-checked monthly as well.

Question 3

How many Belgian B2B email addresses are in the database?

Accepted Answer

We currently hold roughly 529K verified email addresses for Belgian legal entities. Coverage is highest for active corporations and partnerships, and lower for dormant entities and sole proprietors.

Question 4

Are these company emails or direct personal emails?

Accepted Answer

It's a mix of company emails (info@, contact@, sales@) and direct emails of small-business owners. For specific job-title or function-level direct emails (e.g. CMO, Head of HR), ask our team — we offer that as a list-broker enrichment service alongside the standard email list.

Question 5

What format do I receive the email list in?

Accepted Answer

Self-serve platform exports are Excel (.xlsx) and CSV. Custom lists are delivered as Excel with one row per company and columns for: company name, registration number, email, address, postcode, city, region, SIC code, revenue band, employee count, and director details where publicly available.

Question 6

Can I filter by city or region?

Accepted Answer

Yes — pick one or more of the top Belgium cities directly in the builder above. Region-level filtering and city combinations beyond the top 10 are available on the platform and for custom orders.

Question 7

How fresh is the email data?

Accepted Answer

The full KBO/BCE (Crossroads Bank for Enterprises) base is refreshed monthly and email addresses are re-validated against a deliverability score on the same cadence. Records that hard-bounce twice in a row are flagged as inactive and excluded from new exports. New registrations typically appear in the list within 2–3 weeks.

Question 8

Can I get a sample before I buy?

Accepted Answer

Yes. The builder above shows a free preview of 10 B2B emails before any purchase. For a custom list, you can request a free 10-email sample via the request form or by emailing sales@companydata.com.
