Email Marketing and Cold Outreach Laws by Region: GDPR, CAN-SPAM, CASL, and More
A high-level overview of email marketing and cold outreach regulations across different regions. Understand the key differences between major frameworks and how to stay compliant without becoming a legal expert.
Important Disclaimer
This article provides a general educational overview of email marketing regulations and is not legal advice. Laws change frequently, and enforcement varies by jurisdiction. Always consult with a qualified legal professional before implementing email marketing campaigns, especially when operating across multiple regions. Compliance requirements may differ based on your specific business context.
Why Email Marketing Laws Matter
The Cost of Non-Compliance
Email marketing violations can result in significant penalties that threaten business viability. Understanding the stakes helps prioritize compliance.
- GDPR fines: Up to 20 million euros or 4% of global annual revenue
- CAN-SPAM penalties: Up to $51,744 per individual email violation
- CASL fines: Up to $10 million CAD per violation for businesses
- Reputation damage: Public enforcement actions damage brand trust
B2B vs B2C: Does It Matter?
Some regions treat business-to-business (B2B) and business-to-consumer (B2C) communications differently, but this distinction is often misunderstood:
- GDPR applies equally to B2B and B2C communications
- CAN-SPAM has some B2B flexibility but still applies
- CASL requires consent for most B2B communications
Jurisdiction Complexity
Email laws typically apply based on where the recipient is located, not where you are based. This creates compliance complexity for international outreach.
- Recipient location matters: Email to EU residents triggers GDPR regardless of sender location
- Multiple laws apply: One campaign may need to comply with several frameworks
- Strictest rule wins: When in doubt, follow the most restrictive applicable law
Key Concepts Across All Laws
Despite differences, most email regulations share common requirements that form the foundation of compliant outreach.
- Sender identification: Recipients must know who is contacting them
- Opt-out mechanism: Recipients must be able to stop receiving emails
- Honest content: No deceptive subject lines or misleading headers
- Physical address: Most laws require a valid postal address
CAN-SPAM Act (United States)
The Controlling the Assault of Non-Solicited Pornography And Marketing (CAN-SPAM) Act of 2003 establishes requirements for commercial email in the United States. It is often considered one of the more permissive frameworks globally because it uses an opt-out model rather than requiring prior consent.
Core Requirements
- 1No false or misleading header information
Your "From," "To," "Reply-To," and routing information must be accurate and identify the person or business who initiated the message.
- 2No deceptive subject lines
The subject line must accurately reflect the content of the message.
- 3Identify the message as an ad
The law gives you flexibility in how to do this, but you must disclose that your message is an advertisement.
- 4Include your physical postal address
Your message must include your valid physical postal address. This can be a street address, post office box, or private mailbox.
- 5Provide a clear opt-out mechanism
Tell recipients how to opt out of receiving future email from you. The opt-out mechanism must be easy to find and use.
- 6Honor opt-out requests promptly
You must honor opt-out requests within 10 business days. You cannot charge a fee or require any information beyond an email address.
Key CAN-SPAM Characteristic
CAN-SPAM is an opt-out framework. This means:
- You can send the first email without prior consent
- Recipients must be able to opt out easily
- Once opted out, no further emails are permitted
Common Misconceptions
- CAN-SPAM does not legalize all cold email. Other laws like TCPA (for SMS) and state laws may still apply.
- Email service providers may have stricter rules. Even if legal, your ESP might not allow cold outreach.
- B2B is not exempt. CAN-SPAM applies to commercial email regardless of whether recipients are businesses or consumers.
Penalties
Each separate email in violation of CAN-SPAM is subject to penalties of up to $51,744. The FTC, state attorneys general, and ISPs can bring enforcement actions.
GDPR (European Union)
The General Data Protection Regulation (GDPR) is a comprehensive privacy law that applies to processing of personal data of individuals in the European Union. For email marketing, GDPR works alongside the ePrivacy Directive to create one of the strictest regulatory frameworks globally, requiring explicit consent before sending marketing communications.
Consent Requirements
GDPR requires lawful basis for processing personal data. For direct marketing, consent is typically required and must meet strict standards:
- Freely given
Consent cannot be a condition of service unless necessary for that service.
- Specific
Consent must be for clearly stated purposes, not bundled with other consents.
- Informed
Individuals must understand what they are consenting to.
- Unambiguous
Requires a clear affirmative action. Pre-ticked boxes do not count.
- Withdrawable
Must be as easy to withdraw consent as it was to give it.
Legitimate Interest Exception
Some B2B cold outreach may be possible under the "legitimate interest" legal basis, but this requires:
- A documented legitimate interest assessment
- Clear relevance between your offering and the recipient's business needs
- Minimal processing of personal data
- Easy opt-out in every message
Note: This is a complex area. Some member states have stricter interpretations. Legal advice is strongly recommended.
GDPR Penalties
GDPR violations can result in substantial fines:
- Standard violations: Up to 10 million euros or 2% of global annual turnover
- Serious violations: Up to 20 million euros or 4% of global annual turnover
Additional GDPR Requirements for Email Marketing
Data Subject Rights
Recipients can request access, correction, deletion, or portability of their personal data.
Record Keeping
You must maintain records of consent, including when, how, and what was consented to.
Privacy Policy
A clear, accessible privacy policy explaining data processing is required.
Data Protection Officer
Large-scale email operations may require appointing a DPO.
Cross-Border Transfers
Sending data outside the EU requires appropriate safeguards.
Breach Notification
Data breaches must be reported to authorities within 72 hours.
CASL (Canada)
Canada's Anti-Spam Legislation (CASL) is one of the strictest anti-spam laws globally. It requires express consent before sending Commercial Electronic Messages (CEMs) and applies to any email sent to or from a computer in Canada. CASL's opt-in requirement makes cold outreach to Canadian recipients particularly challenging.
Express Consent Requirements
CASL requires express consent (opt-in) before sending commercial messages. This consent must include:
- Clear identification
The person seeking consent and the person on whose behalf consent is sought must be identified.
- Purpose statement
A statement of the purpose for which consent is being sought.
- Contact information
Mailing address and either phone number, email, or web address.
- Withdrawal statement
A statement that consent can be withdrawn at any time.
Implied Consent Exceptions
CASL does allow for implied consent in limited circumstances:
- Existing business relationship: 2-year window from last purchase or transaction
- Existing non-business relationship: 2-year window from membership, donation, or volunteer activity
- Inquiry relationship: 6-month window from an inquiry or application
- Conspicuous publication: Business contact info published without "no unsolicited emails" statement
CASL Penalties
- Individuals: Up to $1 million CAD per violation
- Businesses: Up to $10 million CAD per violation
- Directors/Officers: Can be held personally liable
Message Requirements Under CASL
Identification
- Name of sender
- Mailing address
- Phone or email or URL
Unsubscribe
- Clear unsubscribe mechanism
- Valid for at least 60 days
- Processed within 10 business days
Record Keeping
- Proof of consent
- Date and method obtained
- Purpose stated at collection
UK PECR (Post-Brexit)
Following Brexit, the UK has its own data protection framework combining the UK GDPR with the Privacy and Electronic Communications Regulations (PECR). For email marketing, PECR sets out specific rules that largely mirror GDPR requirements but with some nuances for B2B communications.
Individual Subscribers
For individuals (including sole traders and some partnerships), PECR requires:
- Prior consent before sending marketing emails
- Clear identification of the sender
- Valid contact address for opt-out requests
- Honoring opt-out requests promptly
Corporate Subscribers
For limited companies and public limited companies (corporate subscribers), PECR is slightly more permissive:
- Marketing emails can be sent without prior consent
- Must still identify the sender
- Must provide valid opt-out mechanism
- UK GDPR still applies to any personal data processed
Important Caveat
Even when emailing corporate subscribers, if you are using an individual's name and work email address, you are processing personal data. This means UK GDPR applies, and you will need a lawful basis for that processing (typically legitimate interest, which requires a balancing test).
Other Regional Laws to Know
Australia (Spam Act 2003)
Opt-in required. Sender identification and unsubscribe mechanism mandatory. B2B has limited exceptions for inferred consent based on published business addresses.
Brazil (LGPD)
Similar to GDPR. Requires lawful basis for processing personal data. Marketing typically requires consent. Legitimate interest may apply for B2B with careful documentation.
Japan (Act on Specified Commercial Transactions)
Opt-out system similar to CAN-SPAM. Must include sender identity, contact info, and unsubscribe method. B2B communications have more flexibility.
New Zealand (Unsolicited Electronic Messages Act)
Opt-out model. Must include accurate sender info, functional unsubscribe, and valid physical address. Consent can be inferred from certain business relationships.
Singapore (Spam Control Act)
Opt-out model. Requires sender identification, valid contact details, and functioning unsubscribe. Must honor opt-out within 10 business days.
India (IT Act & DPDP Act)
The Digital Personal Data Protection Act (2023) introduces consent requirements similar to GDPR. Still being implemented, with regulations evolving.

- Maintain a suppression list of opted-out addresses
- Regularly audit your email lists for compliance
- Stay updated on regulatory changes in target markets
- Document your compliance processes and decisions
When in Doubt: The Safest Approach
If you are operating internationally and unsure which laws apply, the safest approach is to:
- Follow the strictest applicable law (usually GDPR or CASL)
- Obtain explicit, documented consent before sending
- Provide clear identification and unsubscribe options
- Keep detailed records of all consent
- Consult with legal counsel for complex situations
Key Takeaways
Recipient Location Determines Applicable Law
Where your recipients are located matters more than where you are based. Email to EU residents triggers GDPR compliance regardless of your location.
Opt-In vs Opt-Out: Know the Difference
CAN-SPAM allows opt-out (first email without consent). GDPR and CASL require opt-in (consent before first email). UK PECR has different rules for individuals vs corporations.
Documentation Is Critical
Keep records of consent: when it was obtained, how, and what was consented to. This is essential for demonstrating compliance if ever challenged.
B2B Is Not Always Exempt
While some laws treat B2B differently, personal data protection rules (like GDPR) apply whenever you process individual contact information, regardless of business context.
When in Doubt, Be Conservative
Follow the strictest applicable law. Getting consent and providing clear opt-outs protects you even when regulations are ambiguous.
