Will cannabis or alcohol related email content trigger spam filters?

Summary

While email content related to cannabis or alcohol is not automatically blacklisted, its impact on deliverability is complex and depends heavily on factors beyond just the keywords themselves. Sender reputation, recipient engagement, ESP policies, and compliance with regulations play critical roles. Some ESPs and mailbox providers are more sensitive to these topics due to their association with spam or regulated industries. Building trust through permission-based marketing, high-quality content, and adherence to best practices is essential for avoiding spam filters and ensuring emails reach the intended recipients.

Key findings

  • Sender Reputation is Paramount: A strong sender reputation is the most critical factor. Building and maintaining a positive reputation is key to ensuring your emails are delivered.

  • Context Matters: The context of your email and its relevance to the recipient are crucial. Avoid misleading or aggressive marketing tactics.
  • Some Providers Are More Sensitive: Hotmail, Outlook, and other mailbox providers may apply stricter filtering to content related to regulated industries.

Key considerations

  • Obtain Explicit Consent: Ensure you have explicit permission from subscribers to send them emails.
  • Provide High-Quality Content: Create engaging and valuable content that your subscribers want to receive.
  • Monitor Your Reputation: Regularly monitor your sender reputation and take steps to address any issues.
  • Comply with Regulations: Stay up-to-date with regulations and guidelines related to email marketing and the promotion of regulated products.
