Sending mail involves the process of delivering messages or packages from one location to another. This can be done through various methods, including traditional postal services, courier companies, or electronic mail (email). Each method has its own procedures, costs, and delivery times. When using traditional mail, items are placed in an envelope or package, addressed, and then dropped off at a post office or mailbox. The postal service then sorts and transports the mail to its destination. For electronic mail, users compose messages on a computer or mobile device and send them over the internet, allowing for instant delivery.
