A "Sender" is a person or entity that transmits information, messages, or items to a recipient. This term is commonly used in various contexts, such as communication, shipping, and digital messaging. In the context of email, for example, the sender is the individual who composes and sends the message to another person. In logistics, a sender is responsible for packaging and dispatching goods to a destination. This role is crucial in ensuring that items reach their intended recipients safely and on time. The sender must provide accurate information, such as the recipient's address, to facilitate smooth delivery.
