How to comply with Gmail's new sending rules for bulk email senders?

Summary

To comply with Gmail's new (February 2024) sending rules for bulk email senders (those sending 5,000+ emails/day), authentication via SPF, DKIM, and DMARC is mandatory. Senders must implement a one-click unsubscribe option using the List-Unsubscribe header (RFC8058), ensuring it's easy and adheres to federal law, avoiding complex processes like logins. Spam complaint rates must be kept below 0.3% (ideally lower, like 0.1%), achieved by monitoring feedback loops, promptly removing complainers, and providing relevant, engaging content. While ESPs often handle authentication, verifying one-click unsubscribe implementation is crucial to prevent rejection. Adhering to these rules not only prevents blocking but aligns with broader industry efforts to improve email security and reduce spam.

Key findings

  • Authentication: SPF, DKIM, and DMARC authentication are mandatory for all bulk senders.
  • One-Click Unsubscribe: Implementation of a one-click unsubscribe using the List-Unsubscribe header is essential.
  • Spam Rate Threshold: Maintain a spam complaint rate below 0.3%, with an ideal target below 0.1%.
  • Volume-Based Rules: The rules apply to senders sending 5,000 or more emails per day.
  • ESPs Role: While ESPs handle authentication, ensure proper one-click unsubscribe implementation

Key considerations

  • User Experience: Ensure unsubscribing is easy and avoids unnecessary barriers like logins.
  • Proactive Monitoring: Monitor feedback loops and promptly remove subscribers who complain.
  • Content Relevance: Focus on relevant, engaging content to reduce spam complaints.
  • Legal compliance: Comply with Federal laws regarding unsubscribing processes.
  • Holistic Approach: Address all requirements (authentication, unsubscription, spam) holistically for better deliverability.
