The American Letter Mail Company was a private mail service established in 1851. It aimed to provide an alternative to the existing postal system in the United States, which was often slow and expensive. The company offered lower rates and faster delivery times, appealing to those who needed reliable mail services. The company was founded by William S. Dorr and operated until 1861, when it was forced to cease operations due to legal challenges and competition from the U.S. Postal Service. Despite its short lifespan, the American Letter Mail Company played a significant role in the evolution of mail delivery in America.
