GDPR and B2B Prospecting: What You Are Allowed to Do
GDPR does not ban B2B prospecting: it frames it. A professional email or phone is personal data, but contacting it in a relevant context remains possible under certain conditions. This guide clarifies what you are allowed to do, without jargon. It is not legal advice: when in doubt, consult a legal professional.
The rules to follow in B2B prospecting
1. Identify your legal basis
Any processing of personal data must rest on a legal basis. In B2B prospecting, the most common is legitimate interest: contacting a professional about a topic tied to their role. Unlike B2C, it does not require prior explicit consent, but it requires balancing against individuals' rights.
2. Stay relevant
Legitimate interest assumes the message genuinely concerns the person's role. Sending an HR offer to a CFO, or a generic mass message, weakens that basis. Precise targeting (the right contact, the right topic) is not only about efficiency: it is a compliance requirement.
3. Inform and allow objection
The person must be able to know who is contacting them, why, and to object to the processing easily. Every email must include a clear unsubscribe mechanism, honored immediately. Maintaining a suppression list is both an obligation and a deliverability best practice.
4. Limit the data collected
Collect only the data necessary for your purpose: name, role, professional contact details. The minimization principle rules out hoarding information without a use. Traceable sources make justification easier in case of an audit.
5. Respect regulated channels
Phone has its own rules: in B2C, France's Bloctel list applies. In B2B the rules are looser, but distinguishing professional from personal numbers remains essential. Always adapt the practice to the channel (email, phone, SMS).
What GDPR does not say
Contrary to a common belief, GDPR does not forbid enriching or using professional contact details. It sets a frame: legal basis, relevance, transparency, right to object, minimization, traceability. Targeted, respectful prospecting naturally ticks these boxes — and happens to be the most effective too.
Frequently asked questions
Do you need consent to send a B2B cold email?
Not necessarily: legitimate interest may suffice if the message is relevant to the recipient's role and an easy right to object is offered. B2C, by contrast, generally requires prior consent.
Can you buy or enrich a B2B contact database?
Yes, provided you respect GDPR principles: a defined purpose, relevance, informing individuals, right to object, and traceable sources. The data's provenance must be justifiable.
What must a compliant cold email contain?
The sender's identity, the message's purpose, and a clear, immediate way to unsubscribe. The message must be relevant to the recipient's role.
How long can you keep the data?
As long as necessary for the intended purpose. Data of a prospect who has objected or no longer responds should be purged or anonymized per your retention policy.
