Distribution List
A distribution list is a single named address that, when used as a recipient, expands to deliver a message to every member it contains, letting a sender reach a defined group without naming each individual.
Distribution lists are stored, named groupings of email or messaging addresses that resolve to multiple recipients when a message is sent. They matter in recordkeeping because they shape who actually received a communication, which is often essential to establishing the audience, intent, and obligations tied to a record. When a message is sent to a list, the captured copy frequently shows only the list name rather than the underlying members, so the membership at the time of sending becomes a piece of context that may need to be preserved alongside the message to maintain a complete and trustworthy record.
For example, a policy notice sent to “All-Staff” is one record, but proving who was reached later for an audit, FOIA request, or litigation hold may require reconstructing the list’s membership on that date. Distribution lists differ from a transmission’s visible To, Cc, and Bcc fields: the list is an indirection layer, and its contents can change over time. Treating both the message and the relevant membership as metadata supports defensible retention and disposition.
