# Is Cold Email Legal? GDPR, CAN-SPAM Compliance Guide
## The Short Answer
**Yes, cold email is legal when done correctly.** However, compliance requirements vary significantly by jurisdiction and recipient location. The key is understanding and following the specific regulations that apply to your situation.

## Frequently Asked Questions
### Can I send cold emails to personal email addresses?
Generally avoid personal email addresses (Gmail, Yahoo, Hotmail for personal use). B2B cold email should target business email addresses where there is legitimate business interest. Personal addresses have stricter privacy protections and higher complaint rates.
### Do I need consent for B2B cold email?
Under GDPR, you can rely on legitimate interest for B2B cold email to business addresses. CAN-SPAM does not require prior consent. However, you must always provide easy opt-out and honor unsubscribe requests immediately.
### What happens if I violate email regulations?
Violations can result in significant fines (up to €20M under GDPR, $43K+ per email under CAN-SPAM), ISP blocking, legal action from recipients, and serious reputation damage. Compliance is essential for sustainable email marketing.
### How long do I need to keep compliance records?
GDPR requires data processing records for demonstrating compliance. CASL requires consent records for 3 years minimum. Best practice is maintaining all compliance records (consent, unsubscribes, complaints) for at least 3-5 years.
### Can I buy email lists for cold outreach?
Purchased lists rarely meet consent requirements and often violate regulations. They also have poor deliverability and engagement rates. Focus on building organic lists with proper consent or use legitimate business databases for B2B outreach.
### What about using LinkedIn to find email addresses?
LinkedIn email harvesting violates their terms of service. However, you can use LinkedIn to identify prospects and then find business email addresses through legitimate means (company websites, business directories, email finder tools).
