Mail originally referred to letters, parcels, and packages sent by courier or a dedicated post office from one physical location to another. Historically, they have been transferred by dedicated courier (on horseback or on foot), travelers (who bring mail along with them, though that is on their main purpose), and stagecoach (to maximize profit from driving people through undeveloped areas).
Today, it can also refer to e-mail sent electronically.
