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%.
