Organizations seeking to monitor and assure compliance of email management practices should.

To effectively monitor and assure compliance with email management policies, organizations must maintain comprehensive audit trails and records. Audit trails provide a chronological, unalterable record of all actions performed on an email, such as who accessed, modified, forwarded, or deleted it, and when. This verifiable evidence is essential for internal oversight, responding to regulatory inquiries, and supporting legal discovery, thereby providing assurance that policies are being consistently enforced.

A. Relying on employees to track their own activity is unverifiable, inconsistent, and insufficient for demonstrating organizational compliance to external auditors or legal bodies.
B. Periodically deleting all emails is a blunt retention strategy that can lead to the illegal destruction of records (spoliation) and does not constitute a monitoring mechanism.
D. Limiting email use is a preventative control measure, not a method for monitoring or assuring that the policies governing the remaining email usage are being followed.

1. ISO 15489-1:2016, Information and documentation — Records management — Part 1: Concepts and principles. Section 9.5 ("Monitoring and auditing") states that organizations should monitor records management processes and that "audit trails should be created and retained" to demonstrate compliance.

2. National Archives and Records Administration (NARA). (2017). Criteria for Managing Email Records in Compliance with the Managing Government Records Directive (M-12-18). Section 2.3 requires agencies to "Maintain audit trails for all actions taken to manage email records."
