Each government entity most likely has their own policy(ies); however, the overarching one may be that using personal email for government business must be in compliance with the Federal Records Act (44 U.S.C Chapter 31). The National Archives and Records Administration (NARA) is charged with enforcing the Federal Records Act and Office of Management and Budget (OMB) requirements that include email and instant messages. NARA issued Bulletin 2014-06, Guidance on Managing Email, September 15, 2014, addressed to heads of Federal agencies, states that email sent on personal email accounts pertaining to agency business and meeting the definition of Federal records (44 U.S.C. 3301) must be filed in an agency recordkeeping system.
