What the experts say
11Expert opinions

The impact of hidden unsubscribe links is complex and depends on several factors. Some experts from Email Geeks suggest that if the overall email program is successful (high delivery rates, good engagement), a hidden unsubscribe link might not be a major issue, especially if RFC 8058 standards are met. Recipient engagement and lack of complaints outweigh minor technical issues. However, Spamresource.com and Word to the Wise emphasize that hiding unsubscribe links can violate CAN-SPAM and demonstrate disrespect for subscribers, leading to damaged sender reputation and increased complaints. Focusing on recipient engagement and a positive sender reputation is key.

Key opinions

  • Compliance Variance: Opinions diverge on whether hidden links strictly violate CAN-SPAM, but the spirit is likely violated.
  • Engagement Matters: High engagement and low complaint rates can offset potential negative impacts.
  • RFC 8058 Importance: Meeting RFC 8058 standards for unsubscription is crucial regardless of body link visibility.
  • Reputation Impact: Hiding links can be perceived negatively, damaging sender reputation.
  • CAN-SPAM violation: It violates the CAN-SPAM Act.

Key considerations

  • Prioritize Engagement: Focus on sending valuable content that recipients want to receive to improve engagement.

  • RFC 8058 Compliance: Ensure full compliance with RFC 8058 standards for List-Unsubscribe headers.

What the documentation says
4Technical articles

Hiding unsubscribe links in email footers is generally discouraged based on legal regulations and sender guidelines. While RFC 2369 doesn't explicitly prohibit it, the spirit is against a hidden link. The CAN-SPAM Act requires a clear and conspicuous way to opt-out, and hiding the link directly violates this. Google's sender guidelines emphasize a positive user experience, and hidden unsubscribe links diminish this. GDPR also supports easily withdrawing consent, which hidden links impede. Overall, these documents suggest that hiding unsubscribe links is detrimental to compliance, user experience, and deliverability.

Key findings

  • CAN-SPAM Violation: Hiding unsubscribe links directly violates the CAN-SPAM Act's requirement for a clear and conspicuous opt-out mechanism.
  • Negative User Experience: Google's sender guidelines indicate that hidden unsubscribe links negatively impact user experience and deliverability.
  • GDPR Non-Compliance: Hiding unsubscribe links impedes the GDPR's requirement for easy withdrawal of consent, potentially leading to penalties.
  • RFC 2369 Spirit: While not explicitly forbidden, hiding links is against the intended spirit of RFC 2369, which emphasizes easy opt-out methods.

Key considerations

  • Compliance: Ensure adherence to CAN-SPAM, GDPR, and other relevant regulations regarding unsubscribe mechanisms.
  • User Experience: Prioritize a positive user experience by making the unsubscribe process clear, easy, and accessible.
  • Transparency: Be transparent with recipients about how to unsubscribe from future emails.
  • Legal Risks: Avoid legal risks associated with non-compliance by providing a readily available unsubscribe option.
