Cold email compliance requirements vary by jurisdiction. Here is the complete 2026 compliance guide covering CAN-SPAM, GDPR, CASL, and global requirements.
Cold Email Compliance 2026
Cold email compliance requirements have tightened globally. CAN-SPAM (US), GDPR (EU), CASL (Canada), PDPA (Singapore) and other jurisdictions have specific requirements. This guide covers compliance across the major jurisdictions for 2026.
United States: CAN-SPAM Act
CAN-SPAM requires:
- Accurate header information: From, To, Subject match actual sender
- Functional unsubscribe: One-click mechanism
- Physical address: Valid postal address in signature
- Opt-out processing: Honor within 10 business days
- Commercial email identification: Clear that email is commercial
CAN-SPAM does NOT require opt-in for cold email. Commercial cold email to US recipients is legal with compliance.
European Union: GDPR
GDPR requires different approach — legitimate interest basis for cold email B2B communication:
- Legitimate interest assessment: Document your business reason for emailing
- Data minimization: Only collect necessary prospect data
- Right to be forgotten: Delete on request
- DPA documentation: Document data processing activities
- Cross-border transfer rules: Handle EU-to-non-EU data transfers properly
B2B cold email under legitimate interest is permissible in most EU jurisdictions with proper documentation.
Canada: CASL
CASL is strict — implied consent or explicit opt-in required:
- Implied consent: Existing business relationship or publicly disclosed business contact
- Explicit consent: Opt-in required for most commercial email
- Sender identification: Clear identification of sender
- Unsubscribe: Mandatory in every message
United Kingdom: PECR + GDPR
UK follows GDPR-equivalent rules plus PECR for electronic communications. Similar to EU approach.
Australia: Spam Act 2003
Australia requires consent (express or inferred) for commercial email. Unsubscribe required.
