In Germany, marketing email needs express consent or the four-part customer exception

Do German B2B emails need opt-in, and is double opt-in legally required?

Germany · European Union

In one sentence

Germany defaults to express for marketing email — B2B is not a free pass; the customer exception is four strict conditions.

Plain English

German practice expects express for marketing email, often proven with . There is a customer exception with several cumulative conditions (existing customer relationship, similar goods, at collection and later, etc.). “It’s B2B so fine” is a myth that fails audits.

Why it matters. German addresses on a US Klaviyo account are a common compliance blind spot for global brands.

What to do

Your move — not a lecture

This one needs you

No platform does this for you. One concrete move, then you are done.

can run workflows and store confirmation events.

Your part: scope language, evidence packs, and B2B cold outreach risk.

What to do first

If you cold email German business addresses, stop and get counsel or switch to the four-part customer exception you can actually prove. Cold "legit interest" decks will not save UWG §7.

You can skip this if: You never send advertising email to Germany.

Who this applies to

Anyone advertising by email to recipients in Germany, consumer or B2B.

Checklist

  • 01Use prior express or satisfy every §7(3) condition.
  • 02Keep logs if you use double as proof.
  • 03Do not claim is literally required by the statute text when it is not.
  • 04Expect injunction risk in civil practice; do not invent a verified public fine frequency.

That’s enough to act. Sources and exact wording are below for counsel, bosses, or AI tools that need a citation. Not legal advice.

The exact position

UWG §7 treats advertising by electronic mail without prior express as an unreasonable nuisance, and the BGH has applied protection to business email accounts. The §7(3) existing-customer exception requires all four statutory conditions. is not written as a fifth statutory condition; it is an evidence practice the BGH has treated as potentially suitable to prove consent when challenged. Generic all-partner consent wording is vulnerable.

What happens if you do not

Private injunction exposure is real in German practice (BGH authority). A complete official 2024–2026 fine series specifically for §7 email was not verified in research; do not publish "rarely fined" as a measured fact.

FAQ

Awkward questions

Who is this actually for?

People who ship email and are too busy to re-read every PDF: week-one marketers, lifecycle/CRM, deliverability, multi-country ops, DTC brands, agencies — on Klaviyo, Mailchimp, Braze, HubSpot, SFMC, or something else. Pick your tool and geos so product-specific pages only appear when they match. EU and UK are first-class filters. Not for people who sell tools about email and need a fake score to demo.

Why only ~40 rules? Isn’t that… thin?

On purpose. A wall of 400 undated “best practices” is how you look busy and still get burned. Every page needs a primary source we actually read. Thin and checkable beats fat and folklore. Europe, bulk inbox rules, measurement honesty, and protocol topics like BIMI/DMARC policy are on the shelf when we can cite them — not every Member State and not every vendor myth. Coverage map lists what we still refuse to invent.

Is this legal advice?

No. If it were, you’d have a billable hour and a longer PDF. This is a dated operator reference written by an email geek. Confirm anything high-stakes with counsel who knows your facts. Same for “will this make me compliant?” — no tool does that. Lawyers and judges do. We say what the sources say and what to do first on Monday.

Why no trust score out of 100?

Because we refuse to invent a number you can’t audit. Fake scores sell seed tests and panic. You get findings, dates, and links. If that feels less exciting than a red dial, good — you’re not the red-dial customer.

Why should I trust you more than my ESP’s blog?

ESPs sell seats. Seed-score vendors sell fear. AI invents citations when nobody watches. We sell nothing today — no pixels, no placement scores, no affiliate — so we can say when a tool is the problem. A human verifies, dates, and corrects in public. Tools may help draft; they do not ship unsourced claims. Check the primary links. Fail that test and leave.

Do I need an account?

No. Filters live in this browser and the URL. Share the link. That’s it. Accounts come later only if they earn it — not so we can nurture you about email.

I’m an agency. Where’s multi-client mode?

We tried a client-name CRM on the setup card. It made the product feel like work before it felt useful. Role filters + copy link + one-page brief (optional PDF title) is enough for now. Complexity comes back when the free shelf is habit, not before.

Is the quiet changelog a bug?

No. Quiet means nothing material moved. We don’t invent urgency so the homepage looks “alive.” Sticky risks still show what usually needs a person when the market is still.
