E-mail messages can constitute federal records if they document agency business, policies, decisions, or other activities. E-mail messages may be records if they provide substantive comments on agency actions, document significant decisions, or convey important agency activities. As with paper records, e-mail records must include transmission data identifying senders, recipients, and dates. Attachments are also considered part of the record. E-mail records must be maintained according to approved retention schedules and stored in an accessible recordkeeping system.
