The European Union represents 27 countries, 24 official languages, and a unified regulatory framework that significantly shapes how marketing analytics operates. Understanding GDPR, the Digital Markets Act, and cross-border complexities is essential.
Regulatory Framework
GDPR Deep Dive

- Cross-border transfers: Mechanisms required for non-EU transfers
Consent is Key
Digital Markets Act (DMA)
New regulations affecting major platforms:

- Interoperability requirements
Digital Services Act (DSA)
