Cold Email Compliance: CAN-SPAM, GDPR, and CASL

Cold email is legal in most jurisdictions — when done correctly. The fines for non-compliance are severe.

CAN-SPAM (United States)

The CAN-SPAM Act applies to all commercial email sent to US recipients. Key requirements:

1
Do not use false or misleading header information (From, To, Reply-To must be accurate)
2
Do not use deceptive subject lines — they must reflect the content
3
Identify the message as an advertisement (if it is one)
4
Include your valid physical postal address in every email
5
Provide a clear and conspicuous opt-out mechanism
6
Honor opt-out requests within 10 business days
7
Monitor what others do on your behalf (you are responsible for third-party senders)
Warning
CAN-SPAM violations carry penalties of up to $51,744 per email. A single campaign to 1,000 addresses without proper compliance can result in over $50 million in potential fines.

GDPR (European Union)

GDPR is stricter than CAN-SPAM. Cold B2B email is permitted under legitimate interest, but requirements are more demanding.

Legitimate interest requires: a genuine business reason to contact them, the email is relevant to their role or business, you have done a balancing test (your interest vs their privacy), and you provide easy opt-out.

CASL (Canada)

Canada's Anti-Spam Legislation is the strictest major jurisdiction. Cold email is only allowed under very narrow conditions: you must have an existing business relationship, the recipient's email is conspicuously published, or you have express consent.

Verification and Compliance

Email verification supports compliance in several ways: it ensures you are sending to real addresses (reduces complaints), it identifies role-based addresses (info@, admin@) that should not receive unsolicited email, and it detects disposable addresses that indicate non-genuine signups.

Compliance Checklist

Before sending any cold email campaign, verify every element: physical address in footer, working unsubscribe link, accurate sender information, relevant and non-deceptive subject line, compliant data source documentation, and proper consent records for GDPR/CASL regions.

Key Takeaway
Cold email is legal but heavily regulated. CAN-SPAM requires honest headers and easy opt-out. GDPR requires legitimate interest. CASL requires prior consent or relationship. Non-compliance penalties can reach millions. When in doubt, consult a legal professional specializing in email marketing law.
