History of the Transportation of Mail Prior to establishing the United States postal service, mail was delivered by friends and unofficial messengers. Even after the Postal Department came to be, most mail was delivered on foot or by horseback, but it has been delivered by many modes of transport since. Discover all the ways the mail has been delivered to America. Steamboats Powered Up and Down the Rivers In 1811, the mail caught a ride on the rivers. Through the 1820s, over 200 steamboats carried US mail, bringing it to communities up and down river routes for another forty years until the railways took over.
