Buying lists is getting riskier and less effective. A practical approach to growing the marketing database from relationships your company already has, with emp
For years, the standard way to grow a B2B marketing database was to buy lists, scrape profiles and capture form fills. In Europe that playbook carries growing risk. More than 2,685 fines have been recorded under European data protection law since 2018, and insufficient legal basis is the most frequent ground. Bought contacts are also cold, and cold contacts convert poorly.
The highest-value contacts in any B2B company are the people its employees already work with: customers, partners, prospects, advisers and suppliers. Those relationships live in mailboxes and calendars. They are current, they are warm, and the company has a genuine reason to stay in touch.
The tempting shortcut is a script that pulls every address out of every company mailbox into the CRM. Under GDPR, that is employee monitoring, and an employee's consent to their employer is not treated as freely given. It also exposes contacts nobody chose to share, including personal and sensitive correspondence.
Employee approval only works if it takes seconds. A weekly email listing the contacts found, with one-tap choices and no sign in, turns review into a habit rather than a chore.
RelationLens is built around this approach from the data model up. It reads headers, calendar invitations and saved contacts nightly, keeps unreleased contacts in a physically separate store, delivers a weekly digest, and sends only released contacts to HubSpot or a spreadsheet export.
