The concept of "sender" refers to the originator of a message, object, or communication, whose intent and context shape the act of conveying information. From emotional exchanges to formal transactions, authors have examined this role in varied ways: Chautauqua Institution highlights the compassion behind letters, while William Addleman Ganoe underscores security in military messaging.
Ruth Lamb portrays kindness, Charles DeLano Hine warns of misunderstanding, and Hannah Trager connects sending with mutual exchange. Legal frameworks, like the 1867 Post Office Act, outline changes in ownership, and Charlotte M. Yonge contrasts historical postage practices with contemporary standards. These perspectives reveal the sender as both a producer of meaning and a figure involved in social, legal, and emotional contexts.
