Is it legal to buy a B2B mailing list?

Yes, in most jurisdictions. GDPR (EU), UK GDPR, CAN-SPAM (US), CASL (Canada), and LGPD (Brazil) all permit B2B direct marketing to legal entities with a legitimate interest and a clear opt-out. We restrict our lists to registered legal entities and exclude sole proprietors by default to stay within the B2B exemption.

How many verified B2B emails do you have?

Roughly 17 million verified business email addresses spanning 190+ countries. Coverage is highest in the US, Germany, Netherlands, France, UK, and Poland, each with 1M+ verified addresses. Smaller markets like Estonia or Singapore have around 50K to 100K each.

Where does the email data come from?

Records are tied to legal entities registered in their country's official trade register, then enriched with verified business email contacts collected from public corporate sources. Validity is re-checked monthly against a deliverability score.

Are these company emails or direct personal emails?

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

How fresh is the email data?

The full 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.

What format do I receive the mailing list in?

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, country, registration number, email, address, postcode, city, region, SIC code, revenue band, employee count, and director details where publicly available.

Can I filter by city or region within a country?

Yes. Open the country-specific email-list page (Germany Email List, USA Email List, and so on) for city-level filtering, with that country's top 10 cities pre-loaded as filter pills. Region-level filtering and bespoke city combinations are also available for custom orders.

Can I get a sample before I buy?

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.

What's the difference between building a mailing list here and using a tool like ZoomInfo or Apollo?

ZoomInfo and Apollo are platforms with seat-based subscriptions starting at $10K+/year and contact data sourced from web scraping and community-contributed inputs. We sell B2B mailing lists outright from €34/month, sourced from official registries, with no per-seat lock-in and no scraped personal data. Different model, different price point, different compliance posture.

What happens if records bounce?

We provide free re-validation if a campaign hard-bounces above 3%. Records that hard-bounce twice are flagged as inactive in the base and excluded from future exports. Custom-list orders include a per-record deliverability guarantee.

B2B Mailing Lists

What is a B2B mailing list?

A B2B mailing list is a curated set of business contacts, each with a verified email address, that you build for outbound sales, lead generation, account-based marketing, and CRM enrichment. Unlike consumer mailing lists, a proper B2B list is restricted to legal entities. That means businesses, not individuals, which keeps the list within the B2B exemption under most privacy laws including GDPR, the UK GDPR, and Canada's CASL.

Quality varies wildly across providers. Web-scraped mailing lists often contain stale, undeliverable, or personal addresses (a legal grey area). Verified lists like ours filter for active business entities, re-validate deliverability monthly, and exclude sole proprietors by default so the result is safe to import directly into your sequencing tool.

Compliance

How to legally buy a mailing list

Buying B2B mailing lists is legal in most jurisdictions, including the EU under GDPR, the UK under UK GDPR, the US under CAN-SPAM, and Canada under CASL. Three conditions need to be in place: (1) you can demonstrate a legitimate interest, (2) recipients are business entities and not natural persons, and (3) every outbound message offers a clear one-click opt-out.

What's not legal: scraped personal email addresses, mailing lists sold without an opt-out mechanism, and any list targeting consumers (B2C) without prior consent. Our mailing lists are restricted to business email addresses at registered legal entities and exclude sole proprietors by default. We provide a deliverability score per record, a clear data lineage per country, and free re-validation if your campaign hard-bounces above 3%.
