Why are emails bcc'd, and what is a better solution for managing bcc'd emails for legal reasons?

Summary

BCC is used for privacy, preventing 'reply-all' storms, and archiving for legal compliance, though manual use poses challenges. GDPR and similar regulations necessitate consent, which BCC hinders. While automated solutions like Microsoft Exchange transport rules and Google Workspace data retention policies exist, dedicated email archiving solutions (Varonis, Proofpoint, Barracuda) offer secure storage, advanced search, and compliance features (HIPAA, SOX, GDPR). Experts recommend alternatives to BCC like setting up dedicated machines, using ESPs/CRMs with consent management, mailing list managers (instead of BCC for bulk sends), or mail merge for personalized emails. The key is to prioritize data handling transparency, consent, security (addressing security risks of compromised systems), and consider the ethical implications of BCC.

Key findings

  • BCC Primary Uses: Privacy, preventing reply-all, legal archiving.
  • GDPR Concerns: Inhibits obtaining consent and transparency.
  • Automated Solutions: Exchange transport rules and Google Workspace retention automate archiving.
  • Dedicated Archiving: Offers secure storage, advanced search, and compliance features.
  • Alternative Solutions: Setting up dedicated servers, ESPs/CRMs with consent, Mailing list management, and Mail Merge
  • Security Risks: BCC exposes emails if a recipient's email system is compromised.

Key considerations

  • Data Transparency: Prioritize transparent data handling and obtain consent.
  • Consent Management: Implement robust consent management practices with ESPs/CRMs.
  • Security: Secure archived data and implement access controls.
  • Legal Requirements: Align solutions with relevant legal and regulatory requirements.
  • Evaluate Alternatives: Choose the most suitable alternative based on needs: dedicated solutions, ESPs, mailing list managers, or mail merge.
