Monitoring:

Common mistakes to avoid

Ignoring local regulations: "Email is global" doesn't mean regulations are. Research and comply with laws in every jurisdiction where you send emails.

Making opt-out difficult: Hidden or complex opt-out processes violate regulations and damage trust. Make unsubscribing as easy as possible.

Using misleading subject lines: Deceptive subject lines violate CAN-SPAM and other regulations. Always be truthful about email content.

Neglecting suppression lists: Failing to maintain suppression lists leads to repeated violations. Invest in robust suppression list management.

Assuming B2B exemption applies everywhere: B2B exemptions vary by jurisdiction. Don't assume B2B cold email is automatically compliant—research local laws.

Situations requiring legal guidance:

  • Operating in highly regulated industries
  • Targeting regions with complex regulations
  • Processing large volumes of personal data
  • Uncertainty about compliance requirements
  • Planning significant changes to outreach practices

Working with counsel:

  • Provide context on your outreach practices
  • Share your compliance documentation
  • Ask specific questions
  • Document their guidance
  • Implement recommendations systematically
