Email is a method of exchanging digital messages from an author to one or more recipients. Email works by using a combination of software and internet protocols to send, transmit, and receive messages over the internet.
Here's how the process of sending and receiving emails typically works:
-
The sender composes a message using an email client (either for business or personally) and enters the email addresses of the recipients in the "To," "CC," and "BCC" fields.
-
The email client connects to an email server using Simple Mail Transfer Protocol (SMTP). The email server is responsible for sending emails to the recipients.
-
The email server looks up the domain of the recipients' email addresses to determine the server that handles their email. For example, if the recipient's email address is "john@gmail.com," the email server will look up the "gmail.com" domain and find that it is handled by Google's email servers.
-
The email server sends the message to the recipient's email server using SMTP.
-
The recipient's email server receives the message and stores it in the recipient's mailbox.
-
The recipient can then retrieve the message from their mailbox using a protocol called Post Office Protocol (POP) or Internet Message Access Protocol (IMAP). They can do this using an email client, such as Microsoft Outlook or Gmail, or by logging into their email account on a webmail service.
That's a basic overview of how email works. There are many more technical details involved in the process, but this should give you a general idea of how it works.
