German company websites have to list an email address on their legal notice page, the Impressum. We checked 911 of them. About 1 in 7 also carry a warning about that address. It says, in effect, don't send us ads or we'll take legal action.

**Mostly no. German law treats an ad email to a business like one to a consumer. Both need the recipient's prior, express consent. The only real exception is your own existing customers, under four strict conditions.**

This is general information, not legal advice.

Most articles stop at "you need consent." The useful part is what happens next. German competition law has no government fine for cold email. The risk is a private warning letter, and its price depends on a value that ranged from €100 to €10,000 per email in the 13 court decisions we found. Oddly, a cold call to the same German business can be legal when the cold email isn't.

## What does German law actually say about B2B cold email?

German law bans "unreasonable harassment" in advertising. Section 7 of the Act against Unfair Competition (UWG) lists cases that always count. Number 2 is advertising by "electronic mail" without the recipient's "prior express consent" ([UWG §7(2), checked October 2026](https://www.gesetze-im-internet.de/uwg_2004/__7.html)). The text makes no exception for business recipients.

One email is enough. In 2009 the Federal Court of Justice (BGH), Germany's top civil court, wrote that even a single unsolicited ad email "can be an unlawful interference" with the recipient's business ([BGH I ZR 218/07](https://lexetius.com/2009,2183)). The email was a newsletter sent to a law firm. The court's reasoning was simple. If one email were fine, every sender would send one.

Courts read "advertising" broadly. In January 2026 a Düsseldorf court ruled against a recruiter who had emailed a company's business address several times. The recruiter called it business development. The court said advertising covers anything meant to promote sales. A "talk to us" line on the company's website wasn't consent, and an unsubscribe link didn't fix it ([AG Düsseldorf 290c C 153/25, via IHK Darmstadt](https://www.ihk.de/darmstadt/servicemarken/news/service/kalte-werbung-per-e-mail-gericht-zieht-klare-grenze-7046700)).

The one exception is in §7(3). You can email an existing customer if all four of these are true:

1. You got their email address when you sold them something.
2. You only advertise your own similar products.
3. They haven't objected.
4. You told them they could object when you collected the address, and you tell them again in every email.

That's built for "you bought X, here's X2." It doesn't cover a prospect list.

## Why can you cold call a German business but not cold email it?

The same law sets different bars. For phone calls to businesses, UWG §7(2) no. 1 only needs "at least presumed consent." For email, it needs "prior express consent." A call can be legal on a well-grounded guess. An email can't.

The guess has to rest on facts. The BGH has said a business call is fine only when concrete facts suggest the company would want it. A useful offer alone doesn't count ([BGH I ZR 88/05, 2007](https://rewis.io/urteile/urteil/l93-19-09-2007-i-zr-8805/)). In that case, a company's free listing in an online search directory wasn't reason enough to call and sell it a paid upgrade.

Paper letters are generally allowed unless the recipient has said no, according to a [March 2022 guide from IHK Niederrhein](https://www.ihk.de/blueprint/servlet/resource/blob/5513366/c1dd01c8dd13574d6ea8c9a920dd57e7/werbung-per-telefon-brief-und-e-mail-data.pdf), a regional chamber of commerce.

So the ranking in Germany runs backwards from what most founders expect. **In Germany, a letter is the safest cold channel, a call can be legal, and a cold email almost never is.**

## What happens if you send a German company a cold email anyway?

German competition law has no government fine for cold email. You may have read about a €300,000 fine. That fine exists, but [UWG §20](https://www.gesetze-im-internet.de/uwg_2004/__20.html) applies it to unwanted phone ads to consumers, not to email. GDPR fines are a separate risk, run by data protection authorities.

The real risk is a warning letter, called an Abmahnung. It can come from the company you emailed, which can sue under general tort law. That's how the 2009 BGH case worked. Competitors, trade associations and chambers of commerce can also act under [UWG §8(3)](https://www.gesetze-im-internet.de/uwg_2004/__8.html).

The letter asks for two things. First, you sign a promise to stop, backed by a contractual penalty if you do it again ([UWG §13](https://www.gesetze-im-internet.de/uwg_2004/__13.html)). Second, you pay the sender's lawyer. If you refuse, they can get a court order. Breaking a court order can cost up to €250,000 per breach ([ZPO §890](https://www.gesetze-im-internet.de/zpo/__890.html)).

## How much does a German warning letter cost?

Lawyer and court fees in Germany follow fixed tables. The input is a "value" the court sets for the case. In the 13 decisions we collected, courts set that value anywhere from €100 to €10,000 for one unwanted ad email.

![German courts have valued one unwanted ad email at €100 to €10,000, with a median of €3,000](/images/blog/is-cold-email-legal-in-germany-1.svg)

*Source: German court decisions 2002-2023, n = 13, from court databases, Haufe and beck-aktuell. Values are per email.*

One pattern stands out. The five decisions about a business or work address all landed at €3,000 or more, and four of those recipients were lawyers or law firms. A lawyer can bring the claim without hiring anyone. In the 2023 Berlin case, the lawyer represented himself.

The Berlin court of appeal, the Kammergericht, treats €3,000 per email as its standard value. In 2023 it valued seven emails from five French companies at €18,300 ([beck-aktuell report](https://www.beck-aktuell.de/heute-im-recht/rechtsprechung/kg-streitwert-fuer-unverlangt-an-rechtsanwalt-verschickte-werbemails-2023-12-11)). A follow-up sent right after the first email added only €300. A follow-up sent after the company had already received a warning letter counted the full €3,000.

Here's what those values mean in euros, using the current [lawyer fee table (RVG)](https://www.gesetze-im-internet.de/rvg/__13.html) and [court fee table (GKG)](https://www.gesetze-im-internet.de/gkg_2004/__34.html), checked October 2026:

| Value the court sets | Warning letter fee you repay | You fight it in court and lose, all fees |
|---|---|---|
| €1,000 | €141 | €768 |
| €3,000 (Berlin standard) | €326 | €1,767 |
| €6,000 | €558 | €2,978 |
| €10,000 | €868 | €4,593 |

*Our math, before VAT, first instance, one hearing, no appeal. Warning letter = 1.3 fee plus €20 expenses. Losing in court = three court fees, 2.5 fees plus expenses for each side's lawyer, and the uncredited half of the warning-letter fee.*

The table matches a real case. In 2023 a Munich court set the value at €1,000 and ordered the sender to repay €136.14 for the warning letter, VAT included. That's a 1.3 fee under the fee table of the time. The recipient had claimed €343, calculated on a €3,000 value, and lost the difference ([AG München 161 C 12736/22](https://www.gesetze-bayern.de/Content/Document/Y-300-Z-GRURRS-B-2023-N-2245)). The value isn't a detail. It decides most of the bill.

So one email that draws a letter costs a few hundred euros. That won't sink a company. The signed promise is the real cost, because it follows you around.

## Does GDPR make B2B cold email in Germany worse?

GDPR mostly closes the back door. Some guides say you can rely on "legitimate interest," a GDPR legal basis that lets you use personal data without consent when your interest outweighs the person's. Germany's data protection authorities disagree. Their 2022 guidance says that if competition law doesn't allow a contact channel, "there is already no legitimate interest" ([DSK guidance on direct marketing, PDF](https://www.datenschutzkonferenz-online.de/media/oh/OH-Werbung_Februar%202022_final.pdf)). If the UWG bans the email, GDPR can't save it.

GDPR also has its own fines for using personal data without a legal basis ([GDPR Art. 83](https://gdpr-info.eu/art-83-gdpr/)), so a complaint to a data protection authority is a second route.

What GDPR doesn't add is a big damages claim. In January 2025 the BGH turned down €500 in GDPR damages for one unwanted ad email, because the recipient showed no real harm ([BGH VI ZR 109/23, PDF](https://ppc.land/content/files/2025/03/vi_zr_109-23.pdf)). The order to stop, which the sender had accepted, still stood.

## Is LinkedIn a way around German email rules?

LinkedIn isn't a safe loophole for pitching. A German appeals court wrote in 2023 that "electronic mail" covers "all messages via social media services such as Xing, Facebook, LinkedIn or WhatsApp" ([OLG Hamm 18 U 154/22, para. 45](https://nrwe.justiz.nrw.de/olgs/hamm/j2023/18_U_154_22_Beschluss_20230503.html)). That case was about messages sent through a property portal, so the LinkedIn line is the court's reasoning, not a ruling on a LinkedIn message. The court cited the EU Court of Justice, which reads "electronic mail" broadly.

A LinkedIn connection isn't consent to email, either. In November 2025 a Düsseldorf court ruled against an IT provider that sent a company two ad emails. Its defense was an indirect LinkedIn connection with the managing director. That wasn't consent ([AG Düsseldorf 23 C 120/25, via Scheja & Partners](https://scheja-partners.de/en/insights/duesseldorf-local-court-linkedin-connection-does-not-circumvent-the-uwg/)).

LinkedIn still works in Germany for posting, ads and building a network. A plain connection request with no pitch is a gray area, and I found no ruling on it. The cold pitch in a DM is what courts will likely treat like an email. If you run LinkedIn and email as one sequence, as we argue in [why LinkedIn vs cold email is the wrong question](https://ken.so/blog/linkedin-vs-cold-email), the German version keeps the visibility and drops the cold pitch on both channels.

## How do Germany's neighbors compare on B2B cold email?

Germany isn't an outlier. **Of the eight neighbors we could verify, only France clearly lets you cold email a named business contact without consent.**

| Country | Cold email to a business contact | Source (checked October 2026) |

| Denmark | Consent needed, including messages to social media inboxes. | [Forbrugerombudsmanden chart (PDF)](https://forbrugerombudsmanden.dk/media/02odpcge/hvorn%C3%A5-m%C3%A5-erhvervsdrivende-henvende-sig_2.pdf) |
| Poland | Consent needed since November 2024. Fines up to 3% of revenue. | [prawo.pl](https://www.prawo.pl/biznes/zgody-marketingowe-i-kontakty-handlowe-co-mowi-prawo-komunikacji-elektronicznej,530981.html) |

Luxembourg is left out because we couldn't read its current text. Belgium's guide is from 2005, so check it before relying on it. For the opt-out mechanics in the US and UK, see our [cold email opt-out rules for CAN-SPAM, GDPR and CASL](https://ken.so/blog/cold-email-unsubscribe-requirements).

## How many German companies have already said no in writing?

We couldn't find this number anywhere, so we measured it. We drew a random sample of 1,200 German companies with websites from Wikidata, a free public database. Then we read each one's Impressum and privacy page. 911 had an Impressum we could read.

![95% of German company sites list an email in their Impressum and 15% object in writing to ad emails](/images/blog/is-cold-email-legal-in-germany-2.svg)

*Source: Kenso scan of 911 German company websites, October 2026, n = 911 (eRecht24 sites n = 47). Lines show 95% confidence intervals.*

What we found:

- **95.3%** list an email address in the Impressum (868 of 911). [German law requires one](https://www.gesetze-im-internet.de/ddg/__5.html).
- **15.3%** publish a written objection to ad emails (139 of 911). 136 of those also threaten legal action.
- **.de sites carry the clause twice as often as .com sites**, 18.9% against 9.0%.
- Most clauses sit in the privacy policy (102 sites), not the Impressum (42 sites).

Then came the part that surprised me. Almost nobody writes the clause by hand. 115 of the 139 use the same template sentence, objecting to the use of "contact data published within the scope of the imprint obligation" for unsolicited ads. Sites that credit eRecht24, a popular generator for German legal texts, carry the clause 43% of the time (20 of 47). The rest carry it 14% of the time.

So the objection spreads like a default setting, and plenty of companies probably never decided to add it. That doesn't help you. The clause doesn't change the law, since you needed consent anyway. It changes who's on the other end. A template "no" is still a written "no," on a page any lawyer can screenshot. And our count is a floor, because sites that load their text with JavaScript slipped past us.

## What do founders do instead of cold emailing Germany?

Our own data can't help here. Our clients mostly sell into English-speaking markets, so we have no German reply rates to show you.

If Germany matters to you, here's what I'd do:

1. **Earn the consent first.** Content, webinars and downloads with a clear opt-in checkbox. Keep a record of who agreed to what, and when.
2. **Call with a reason.** A business call can be legal on presumed consent. Have a concrete reason this company would want to hear from you, and write it down before you dial.
3. **Send a letter, with one caution.** Physical mail is generally allowed for business advertising. But [UWG §7(1)](https://www.gesetze-im-internet.de/uwg_2004/__7.html) also bans ads the recipient clearly doesn't want, and the template clause covers the Impressum's postal address too. I found no ruling on letters, so I'd skip companies that carry the clause.
4. **Use LinkedIn for visibility, not pitches.** Post, run ads, connect. Pitch only the people who ask.
5. **Meet people at trade fairs and events.** Ask in person whether you can follow up by email, and note the answer.
6. **Email your existing customers** within the four §7(3) conditions.

For markets where cold email works, Kenso runs done-for-you cold email and LinkedIn outreach on infrastructure we own. That's the setup in [what done-for-you cold email includes](https://ken.so/blog/done-for-you-cold-email).

## Frequently asked questions

### Does German law apply to a US company emailing Germany?

Assume yes if you're advertising to people in Germany. German courts hear these claims against foreign senders. In the 2023 Berlin case, the senders were French companies. Collecting from a company with nothing in the EU is harder, but that's a bet, not a compliance plan.

### Can I email generic addresses like info@ at German companies?

German law makes no exception for generic addresses. Belgium and France do. The objection clauses we found also target exactly the contact details published in the Impressum, which often include an info@ address.

### Can I send one email just asking for permission?

Risky. German courts define advertising very broadly. The BGH even counted a customer-satisfaction survey, sent along with an invoice, as advertising ([BGH VI ZR 225/17, 2018](https://www.otto-schmidt.de/news/wirtschaftsrecht/konsequenzen-bei-kundenzufriedenheitsbefragung-in-der-rechnungs-e-mail-2018-09-14.html)). An email asking a stranger whether you may pitch them will very likely count too.

### What should I do if I get an Abmahnung?

Don't ignore it, and don't sign the promise to stop before a German lawyer reads it. The wording of that promise decides your penalty if it happens again. Just stopping isn't enough. In the 2026 Düsseldorf case, a promise without a penalty clause didn't count.

## The short version

B2B cold email to Germany needs consent, and about 1 in 7 companies have already said so in writing. One mistake costs a few hundred euros. A habit costs thousands, plus a signed promise you can't take back. If you want outbound in markets where it works, [your first campaign is free](https://ken.so/free-campaign).
