Cold outreach in German: tone, timing and examples

Write in German when the reader works in German, and keep to the formal Sie unless they use du first. Be precise, short and factual. Check the law before you email: sources we read say German law (UWG section 7) generally requires prior consent for advertising by email, with a narrow existing customer exception and no clear business exemption. LinkedIn is often the first channel. This is not legal advice.

German speaking markets, Germany, Austria and German speaking Switzerland, are rich for B2B and awkward for the habits that work elsewhere. A breezy first name email with an exclamation mark reads wrong, and in some cases it is not allowed at all. This guide covers language, tone, structure and timing, with examples and translations, and starts with the part that matters most: whether you may send the email.

Can you email a German company without consent?

Start here, because it changes the channel. We are not lawyers, and the sources we read are a vendor blog and a general guide, so treat this as a map for questions to a German lawyer, not an answer.

• A vendor guide to cold email in Germany (Overloop, updated May 2026) summarises German unfair competition law, UWG section 7, as generally requiring prior express consent for advertising by email, and says it applies whether the recipient is a private individual or a business. It describes the rule as having no business to business exemption.
• The same guide describes a narrow existing customer exception under section 7(3), with four conditions: a prior business relationship, similar products or services, no prior objection and a clear opt out in every email.
• It says there is no single automatic fine for every unsolicited email, and lists possible consequences such as injunctions, warning letters from competitors and data protection action.
• A calling guide from Leadfeeder notes that for phone calls to businesses, presumed consent can be enough in some cases. That is a rule for calls. The same guide says little about email.

Compare the US, where CAN-SPAM allows B2B cold email with an opt out. Our post on whether cold email is legal lays out the US, EU, UK and Canadian positions. Germany is stricter than the US, and a campaign copied from an American playbook can land you a warning letter.

What this means in practice: many German outreach programmes start with channels where the person has more control, such as LinkedIn, events and warm introductions, and use email for people who have agreed or who are existing customers. Get advice for your case before you send a single cold email.

What language should you use?

The reader's. If the person's profile, company and site are German, write in German. English works for some tech and international roles, but a German message to a German reader is a signal of care. Our post on writing in the local language gives the evidence: in the Shelly installer programme, the agent wrote in 21 languages, 51% of installers replied in a language other than English, and the agent matched the installer's language in 92% of replies. If someone answers in English, follow them.

Do not machine translate and send. Have a native speaker read your template once. Small errors in gender, case or the formal address are noticed.

Sie or du?

Our guidance, not a measured result:

• Start with Sie. Use "Sehr geehrter Herr Müller" or "Guten Tag Herr Müller" for a first message to someone you do not know, with their surname and, where relevant, title.
• Follow the reader. If they answer with du, switch to du. If they stay with Sie, stay.
• Sector differences. Start ups, creative and software teams often use du among themselves. Industry, finance, law and public bodies lean formal. When unsure, formal is the safe error.
• Never mix. A message that starts with Sie and drifts to du reads as careless.

How should a German message be built?

German business readers tend to value precision, relevance and plain facts over enthusiasm. The structure that works elsewhere still applies, with a different temperature.

1. Greeting. Formal and specific.
2. One concrete reason for writing. A fact about their company or role, not a compliment.
3. What you offer, in one sentence, with a concrete detail. Numbers, standards, certifications where relevant.
4. One clear, modest question.
5. A short close with your name and role.

Avoid superlatives, exclamation marks and promises of dramatic results. A claim you cannot support is a problem anywhere, and especially in a market with strict advertising law.

Example: a LinkedIn first message

German: "Guten Tag Herr Weber, ich habe Ihren Beitrag zur Umstellung auf mehrstufige Qualitätsprüfungen gelesen. Besonders interessant fand ich Ihren Hinweis auf die Dokumentation bei Lieferantenwechseln. Wie lösen Sie das aktuell bei Ihren Zulieferern aus dem Ausland? Mit freundlichen Grüßen, Ivo Petrov"

English: "Good day Mr Weber, I read your post on moving to multi stage quality checks. I found your point about documentation when suppliers change especially interesting. How do you currently handle that for your suppliers abroad? Kind regards, Ivo Petrov"

It is short, formal, specific and ends with one question. There is no link and no pitch.

Example: a follow up

German: "Guten Tag Herr Weber, ich möchte nachfassen, da das Thema bei vielen Einkaufsleitern zurzeit aktuell ist. Falls Sie nicht der richtige Ansprechpartner sind, wäre ich für einen Hinweis dankbar. Freundliche Grüße, Ivo Petrov"

English: "Good day Mr Weber, I wanted to follow up because the topic is current for many purchasing managers at the moment. If you are not the right contact, I would be grateful for a pointer. Kind regards, Ivo Petrov"

The follow up adds a reason and asks for the right person, a pattern that works in many markets. The examples are ours, not tested texts.

What about timing?

Our guidance: weekdays in working hours, with the usual caution that no study we trust gives a best hour (see the best time and day to send cold emails). Two German specifics to plan around: public holidays differ by state, and summer and year end holiday periods thin out replies. Check the holiday calendar of the region before you schedule a campaign. In Sellinger, send windows are set per account with a time zone, so a Berlin morning does not become a Sofia morning by accident.

How does an AI agent handle German?

Sellinger agents write in the prospect's language and follow the language the person replies in. You set a persona and rules, including the form of address, in the instructions: "Write in German. Use Sie with Herr or Frau and the surname. Switch to du only if the person does." Then read the first twenty threads, ideally with a native speaker, and fix the rules where the agent drifted. See personas and tone of voice, and the playbook for replying in the prospect's language.

What about LinkedIn?

LinkedIn is where many German outreach programmes begin, because a connection request can be accepted or ignored and a message follows only after acceptance. The legal question is not the same as for email, since the UWG rule we read is about advertising by email, but LinkedIn has its own limits and its help pages say third party automation violates its User Agreement. Pace the account, keep volume modest and read the threads yourself. Our LinkedIn safety checklist covers the rest. Then, once someone replies and agrees, email is a natural next step.

A checklist

• [ ] I have checked the consent rules for the channel with a German lawyer.
• [ ] The message is in the reader's language, read by a native speaker.
• [ ] I use Sie with the surname unless the reader uses du.
• [ ] One concrete reason, one modest question, no superlatives.
• [ ] Send windows follow German working hours and public holidays.
• [ ] An opt out is honored and recorded.
