Cold Email in Germany: Why UWG Makes It Different

In Germany, sending a B2B cold email without prior consent is treated as unfair competition, not just a data-protection issue — and the practical risk is a cease-and-desist letter from a competitor with their legal costs attached to it. This is the single biggest exception in European outreach, and most advice written for a US audience misses it completely.

This is not legal advice. It's a practical explanation of why Germany behaves differently and what the workable alternatives are. For anything that matters commercially, speak to a German lawyer.

The rule in one paragraph

Germany's Act Against Unfair Competition — the Gesetz gegen den unlauteren Wettbewerb, UWG — treats unsolicited advertising by electronic mail as an unreasonable nuisance (unzumutbare Belästigung) under §7. That applies to business recipients as well as consumers. The exception for existing customers is narrow: broadly, you already sold them something similar, you collected the address in that transaction, and you told them at the time they could object.

For a first cold email to a prospect who has never heard of you, none of that applies.

Why this bites harder than a fine

In most of Europe, breaking the rules on marketing email means a complaint to a data-protection authority. Authorities are slow, usually warn first, and rarely pursue a small sender over a handful of emails.

Germany has a second, faster mechanism: **the Abmahnung** — a formal cease-and-desist letter. It can be sent by:

• the recipient,
• a competitor of yours,
• or a qualified trade association.

The letter typically demands you sign a Unterlassungserklärung (a binding promise to stop, with a contractual penalty for each future breach) and pay the sender's legal fees. Fees for a single letter commonly run into the high hundreds of euros; the penalty clause bites much harder if you slip later.

The critical detail: your competitors can do this to you. That changes the risk profile entirely. A data-protection authority has limited resources and no commercial motive. A competitor annoyed that you're emailing their market has both.

What people get wrong

"It's B2B, so it's fine." No. §7 UWG covers business recipients. The B2B carve-outs that exist in the UK and France do not exist here in the same form.

"Legitimate interest under GDPR covers me." These are two different questions. GDPR governs whether you may process the data; UWG governs whether you may send the message. Satisfying the first does nothing for the second.

"I'll just use a generic address like info@." The address type doesn't create the exception. Writing to info@ rather than a named person helps on the GDPR side, not the UWG side.

"It's one email, nobody will care." One email is enough to trigger an Abmahnung. Volume affects how likely you are to be noticed, not whether the act was lawful.

What actually works in Germany

You can absolutely sell to German businesses. You just can't open with an unsolicited email.

Phone first. Cold calling B2B in Germany sits under a different and somewhat more permissive test than email — but it is also restricted and fact-dependent. Take advice before building a calling operation.

LinkedIn. A connection request with a short, relevant note is not electronic mail under §7. This is the most common route for reaching German prospects at scale.

Inbound and content. Rank for what they're searching, let them come to you, and you have consent by definition.

Physical mail. Genuinely still works in Germany, and sits outside §7 entirely.

Events and trade fairs. Germany's Messe culture is strong. A conversation at a stand gives you a lawful basis to follow up.

Referrals and partners. An introduction from someone they know converts better anyway.

Explicit opt-in. Build a list where people ask to hear from you. Slower, and the only fully clean path to email.

The practical rule for a European campaign

If you're running outreach across several countries, the simplest safe policy is:

Exclude Germany from cold email. Reach German prospects through LinkedIn, content, phone or events.

That's what we recommend to our own users. It costs you one market's email channel and removes the sharpest legal risk in Europe.

For the rest of the continent the picture is very different — the UK allows B2B email to corporate bodies, France permits it on legitimate interest, and the Netherlands, Spain and Poland all allow it with care. We cover the differences in is cold email legal in Europe, and the data side in GDPR and cold email.

Summary

• §7 UWG treats unsolicited commercial email to businesses as unfair competition.
• The enforcement risk is a competitor's Abmahnung with costs, not a regulator's fine.
• GDPR legitimate interest does not help — it answers a different question.
• One email is enough to trigger it.
• Reach German prospects via LinkedIn, phone, content, post or events instead.
