Should I delete competitor emails from my suppression list if they request it under GDPR?

Summary

Under GDPR, individuals have the right to request the deletion of their personal data. Experts and marketers recommend a nuanced approach regarding competitor emails on suppression lists. Complying with erasure requests is crucial, but a 'legitimate interest' might allow retaining minimal suppression records (email and request date) to prevent future contact, used *only* for that purpose. Domain-level blocking offers a privacy-friendly alternative. Legal counsel is strongly advised to navigate the complexities. Data retention should be transparent, and consider anonymizing data or if there is no business relationship delete it. Maintain a clean list, and treat erasure with the same urgency as removing bounces/complaints.

Key findings

  • Right to Erasure: GDPR grants individuals the right to have their personal data erased upon request (right to be forgotten), though not absolute.
  • Legitimate Interest Exception: Retaining minimal data for suppression to prevent future contact may be considered a legitimate interest, requiring careful consideration and documentation.
  • Domain-Level Suppression: Suppressing entire domains (instead of individual emails) is a privacy-friendly alternative where appropriate.
  • Transparency and Consent: Be transparent with users about data retention policies. Ensure you had explicit consent.
  • The lawyer is liable: Following the lawyer's advice is important for the company

Key considerations

  • Legal Advice: Consult legal counsel to ensure compliance with GDPR and determine the best approach for your specific situation.
  • Purpose Limitation: If retaining data, strictly limit its use to suppression only and document the legitimate interest.
  • Minimal Data: Retain the bare minimum data necessary for suppression (e.g., email address and date of request).
  • Alternative Solutions: Explore alternatives like anonymization or domain-level blocking before retaining personal data.
  • No Business Relationship: If no business relationship exists, prioritize deleting the data upon request.

Under GDPR, individuals have the right to request the deletion of their personal data. However, the consensus among email marketers is nuanced regarding competitor emails on suppression lists. While honoring deletion requests is paramount, retaining minimal suppression records to prevent future contact is often considered a legitimate interest, provided it's used solely for that purpose.

Key opinions

  • Legitimate Interest Exception: Maintaining a suppression list to avoid future unwanted contact might be a legitimate interest under GDPR, but this requires careful consideration and legal justification.
  • Minimal Data Retention: If retaining data for suppression, keep only the minimal necessary information (e.g., email address and date of request) and use it *only* for suppression purposes.
  • Domain-Level Suppression: Consider suppressing entire domains instead of individual email addresses to avoid processing personal data.
  • Transparency: Be transparent with users about your data retention policies and the use of suppression lists.

Key considerations

  • Data Breach Risk: Consider the potential consequences of a data breach and whether retaining competitor emails increases your risk.
  • Alternative Solutions: Explore alternative solutions such as anonymization or domain-level blocking before retaining personal data.
  • Purpose Limitation: Clearly define and document the purpose for retaining data on a suppression list, ensuring it aligns with legitimate interest and is limited to preventing future contact.
