mail systems

Mail systems refer to the organized methods and processes that facilitate the sending and receiving of letters and parcels. This includes postal services, like national postal offices, as well as private courier companies. Mail systems involve collection points (such as mailboxes), sorting facilities to organize mail, transportation networks (trucks, planes), and delivery systems to ensure items reach their intended addresses. They serve as crucial infrastructure for personal communication, business transactions, and global trade, adapting over time to include digital communications and tracking technology for efficiency and convenience.
