How does email work?

Email, or electronic mail, uses the internet to transmit messages between users. When a message is sent, it is broken down into small packets of data that are sent over the internet to the recipient's email server. The recipient's server then reassembles the packets and delivers the message to the recipient's email inbox. Email relies on different protocols such as SMTP (Simple Mail Transfer Protocol) for sending emails and POP3 (Post Office Protocol version 3) and IMAP (Internet Message Access Protocol) for receiving emails. These protocols define the rules for how email servers communicate with each other and how messages are formatted and delivered. Overall, email is a convenient and efficient way to communicate with people all over the world.
