Overview

Datatilsynet enforces the GDPR in Denmark, and cookie consent must be informed and freely given.
Danish is the search language, with English widely understood in B2B; Google is dominant.
In Europe, WhatsApp marketing is treated like other electronic marketing: you need a lawful basis, usually consent, and you must be transparent about how contact data is used under GDPR or UK GDPR.
European countries regulate marketing calls through national laws and do-not-call or objection registers, and automated (recorded) marketing calls generally require prior consent.
Advertising Rules
The Consumer Ombudsman's guidance requires clear labelling of advertising, including influencer and social media posts.
