Which type of mail is the most common type of mail correspondence?

• A. Routine mail
• B. Legal mail
• C. Privileged mail
• D. Digital mail

Answer: (A)

Routine mail represents everyday, ordinary letters and parcels that go through standard processing. It’s the most common type because it covers the bulk of daily communications—bills, notices, personal letters, and typical shipments. Legal or privileged mail require special handling and occur far less often, and digital mail refers to electronic messages, not physical mail, so it isn’t counted among the physical mail types.
