GDPR and cold email
GDPR does not ban B2B cold email, but it regulates the personal data behind it, including a prospect's name and work email address. Most B2B senders rely on legitimate interest as their lawful basis, which requires a documented balancing test, clear disclosures, and an easy way to object.
What is gdpr and cold email?
The GDPR covers companies established in the EU and companies anywhere in the world that offer goods or services to people in the EU, which is what cold outreach to EU prospects is, and the UK GDPR mirrors it for the UK. A named work address like jane.doe@company.com identifies an individual and is personal data; a generic address like info@company.com usually is not. Building a prospect list, enriching it, storing it, and emailing it are all processing, so a cold email program targeting EU or UK prospects sits squarely inside the regulation.
Every processing activity needs a lawful basis, and consent is impractical for cold outreach by definition, so most B2B senders rely on legitimate interest under Article 6(1)(f). GDPR's Recital 47 explicitly says direct marketing may be a legitimate interest, but relying on it means passing a three-part test: a purpose test (you have a genuine commercial interest), a necessity test (the processing is necessary to pursue it), and a balancing test (your interest is not overridden by the person's rights and reasonable expectations). Relevance is the practical heart of the balancing test. A tightly targeted message to someone whose role makes your offer plausibly useful balances very differently from a blast to a scraped list, and regulators expect the assessment to be documented, typically as a legitimate interests assessment.
GDPR also imposes transparency duties. Article 14 says that when you collect someone's data from a source other than the person, you must tell them who you are, why you are processing their data, your lawful basis, where the data came from, how long you keep it, and what rights they have, at the latest at the time of your first communication with them. In practice senders meet this by linking a privacy notice from the email. Article 21 gives an absolute right to object to direct marketing: if a prospect objects, you stop, with no balancing and no conditions, and you suppress the address so they are never contacted again. Making objection easy, with a clear opt-out line or link in every message, is both required in spirit and protective in practice.
The sending itself is governed by separate ePrivacy rules that vary by country. The UK's PECR distinguishes corporate subscribers, such as employees of limited companies and LLPs, from individual subscribers, such as sole traders and some partnerships. Marketing email to corporate subscribers does not require PECR consent, though the UK GDPR still applies to the individual's data and you must not disguise your identity and must provide a valid opt-out address. Individual subscribers are treated like consumers and generally require consent. Some EU member states, Germany among them, set a consent standard for marketing email that covers B2B, so country-by-country checks matter. This page is general information, not legal advice.
Why it matters in cold email
If any slice of your target market is in the EU or UK, lawful basis, disclosures, and objection handling stop being abstractions and become operational requirements for every campaign. The most serious GDPR infringements carry fines of up to 20 million euros or 4 percent of global annual turnover, whichever is higher, which is reason enough to take the paperwork seriously. The useful part is that what GDPR pushes you toward, tight targeting, accurate data, clear sender identity, and fast suppression, is the same discipline that tends to earn replies and protect deliverability anyway.
How Sendful handles it
When campaigns touch EU or UK prospects, Sendful builds them around tight ICP targeting, verified data, an easy way to object in every message, and immediate suppression of anyone who does. Clients own their lists and data throughout. We are operators, not lawyers, so for regulated markets we work alongside guidance from your counsel.
Is cold email illegal under GDPR?
Not categorically. GDPR regulates the processing of personal data, and B2B senders can typically rely on legitimate interest as a lawful basis if they pass and document the balancing test, disclose the required information, and honor objections immediately. Separate national ePrivacy laws still apply to the sending itself, and some countries require consent even for B2B, so check each market. This is general information, not legal advice.
Can I use legitimate interest to send cold email?
Usually yes for B2B, and GDPR's own recitals recognize direct marketing as a potential legitimate interest. You need a documented assessment showing your purpose is genuine, the processing is necessary, and the prospect's rights do not override your interest. Narrow targeting to people whose role makes your offer relevant is what makes the balancing test workable.
Do I need consent to cold email someone in the UK?
It depends who they are. Under PECR, marketing email to corporate subscribers, such as employees at limited companies and LLPs, does not require consent, while individual subscribers, including sole traders and some partnerships, are treated like consumers and generally do. Either way the UK GDPR applies to any named individual's data, you cannot hide who you are, and you must provide a working opt-out.
