Email marketing to a global audience means navigating a complex patchwork of regulations. Each country or region has its own rules about consent, content, and data protection. This comprehensive guide covers email marketing laws across major markets, helping you build compliant international email programs.
The Global Email Compliance Landscape
Before diving into specific countries, understand the broader landscape.

Common Requirements Across Jurisdictions
Despite differences, most email laws require:
- Sender identification
- Accurate subject lines
- Working unsubscribe mechanism
- Physical contact information
- Honoring opt-out requests promptly
Applying the Strictest Standard
