Business contacts: quality before volume

Updated 2026-08-22 · 5 min read

Business contacts are the public channels through which companies can be approached with commercial offers. Their value comes not from volume but from how closely they match your ideal customer profile.

Below are four criteria for judging a contact base.

Four quality criteria

If one is missing, the whole campaign result suffers.

  • Coverage — how many rows actually carry a contact
  • Freshness — when the dataset was last refreshed
  • Segmentability — whether you can filter by sector, size and region
  • Traceability — whether every row has a registry code for verification

Lawful use in Estonia

A commercial offer to a company's general contact is allowed when it concerns the recipient's business activity, the sender is identifiable and the message carries a working opt-out link. Opt-outs must be honoured immediately and permanently.

Where to get business contacts

In the Kontabase composer you pick sector, county, legal form and size and immediately see how many business contacts fall into the slice and what it costs. The free 25-row sample comes from the same filters.

Frequently Asked Questions

Are business contacts personal data?
A company's general contact is not personal data in the same sense. A named work email is, and requires legitimate interest plus an opt-out.
What list size should I start with?
300–800 carefully filtered contacts usually beat tens of thousands of random rows.
Can I get the contacts as CSV?
Yes, you can choose between XLSX and CSV.
