Is it legal to opt users back into email lists for operational emails after they've opted out and are there alternative campaign setups?

Summary

Opting users back into marketing email lists after they've unsubscribed is generally illegal and unethical, violating GDPR and CAN-SPAM principles, and eroding user trust. Transactional or operational emails are a nuanced exception but must be handled carefully, with a clear distinction from marketing content and an easy opt-out. A recommended approach involves setting up separate campaigns and lists for marketing and operational emails, offering distinct subscription options and preference centers. Explore alternative channels like SMS, push notifications, or in-app messages for critical updates to users who've unsubscribed from email, ensuring transparent communication and user control.

What email marketers say
7Marketer opinions

The consensus is that re-opting users into marketing emails after they've unsubscribed is a bad practice and likely illegal. However, operational emails are treated differently but require careful consideration. Segmentation is crucial to distinguish between operational and marketing communications, offering users granular control over their subscriptions via preference centers and separate opt-ins. Alternative communication channels like SMS and in-app notifications should be explored for critical updates, especially for those who've opted out of email.

Legal documentation emphasizes that re-opting users into email lists after they've opted out generally violates consent principles outlined in GDPR and is potentially deceptive under CAN-SPAM. Transactional emails are exempt from consent requirements only if their primary purpose is transactional, and marketing content requires explicit consent. The creation of distinct lists for transactional and marketing emails enables better user control.

Key findings

  • GDPR Consent Violation: Re-opting users after they've opted out violates GDPR's principle of freely given consent.
  • CAN-SPAM Concerns: While not explicitly forbidden, re-opting without consent may be a deceptive practice under CAN-SPAM.
  • Transactional Email Exemption: Transactional emails are exempt from consent requirements if primarily transactional, but marketing content requires consent.
  • Distinct Lists Key: Managing distinct lists for different email types allows users to better control their preferences.

Key considerations

  • Compliance with Regulations: Ensure compliance with GDPR, CAN-SPAM, and other relevant regulations.
  • Clear Purpose Definition: Clearly define the purpose of emails (transactional vs. marketing) to ensure proper handling.
  • User Control: Provide users with control over the types of emails they receive.
  • Explicit Consent: Obtain explicit consent for any marketing content included in emails.
