Camel mail

Mail delivery by animals has been used in many countries throughout history. It used to be the only way to quickly transport large bundles of letters over long distances, until motorised vehicles became more widespread. Mail is still delivered by animals in a few remote locations that lack vehicular road access.

The term "snail mail" is a derogatory retronym used to refer to the delivery of letters in contrast to the immediacy of electronic mail.

In Australia camels were used to transport mail and supplies from Oodnadatta to Alice Springs until around 1929 when the railroad superseded it. The journey of around 520 kilometers took Afghan cameleers (Muslims and expert cameleers came from around the British Empire, mainly from Afghanistan and Pakistan, signed a 3 years contract and often married and created families in Australia) around four weeks. The service was celebrated by descendants of the cameleers in 2002.

Dogs were used to deliver mail when pulling a dogsled. Dogsled mail saw limited use in the northern parts of Alaska and Canada during the Klondike gold rush (1896–1903) In the early years of Alaska settlement, there was no regular mail service to the interior post offices during the winter months (October to May), although individuals might agree to transport letters to coastal areas. Regular service seems to have begun around the 1910s, replaced in the 1930s by small aircraft.

Horses were a primary method of delivering mail and messages for many years in different countries around the world. Riders on horseback could take small bundles quickly, while carts pulled by horses could take large amounts of mail very long distances.

Relay rider networks were a common feature of every ancient empire. They were primarily for the exclusive use of the government or military and carried no civil correspondence as a rule. Later, post riders became popular when there was an obvious demand for the transportation of public correspondence.
