This isn't legal advice. It's a plain-English guide to the basics. Read the Information Commissioner's guidance on direct marketing, and take your own advice if you're unsure.

Two sets of rules sit over business email in the UK. UK GDPR covers personal data, and a named person's work email is personal data. PECR, the Privacy and Electronic Communications Regulations, covers electronic marketing. Between them they answer one question: can you send this email to this person?

The recipient decides which rules apply

PECR treats two kinds of recipient differently.

  • Corporate subscribers. Limited companies, LLPs and some other organisations. You don't need their consent for a marketing email, but you must say who you are and give a way to opt out, and your email should be relevant to their business.
  • Individual subscribers. Sole traders and ordinary partnerships. They're treated like consumers, so marketing email generally needs their consent.

That's why a sole trader's record is different from a limited company's, and why we show what kind of business each one is.

What to do for every email

  • Say clearly who you are and, if relevant, who you act for.
  • Give a simple, working way to opt out, and honour it promptly.
  • Keep your own list of people who've asked to stop.
  • Write about something relevant to them in their working role.
  • Remember UK GDPR rights still apply to the person: they can object, and you stop.

Calls

Marketing calls have their own registers. The Telephone Preference Service covers individuals, including sole traders, and the Corporate TPS covers companies. Check them before you ring. Adapt Leads doesn't screen numbers for you, so that check is yours.

What Adapt Leads does and doesn't do

It shows what kind of business each record is, labels every email, keeps a do-not-contact list and applies a removal request everywhere. It doesn't decide for you whether you may contact someone. You're the sender, and the responsibility is yours. Our UK GDPR and PECR page sets it out.

When in doubt

If a recipient is a sole trader and you don't have their consent, use a channel with different rules, or don't send. A short, honest, relevant email to a company's named decision-maker, with a clear opt-out, sits on much firmer ground.
