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?
In one sentence
Germany defaults to express for marketing email — B2B is not a free pass; the customer exception is four strict conditions.
Emailrules interpretation
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.

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.

Source fact
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 A complete official 2024–2026 fine series specifically for §7 email was not verified in research; do not publish "rarely fined" as a measured fact.
