What is email and how does it work?

Electronic mail, also known as email, is a communication system that allows you to send and receive messages over a computer network. To do this, you need an email address, which identifies the sender and recipient, and an email provider, which is the service that manages the sending and receiving of messages.

Email messages may contain text, images, attachments, links, and other multimedia elements. In addition, they can be sent individually or in bulk, depending on the number of recipients.

Email works through two types of servers: outgoing servers and incoming servers. The outgoing servers are responsible for sending the email from the sender's account to the incoming servers, which are the ones that deliver it to the recipient's inbox.

The most used protocols for the operation of email servers are:

  • SMTP (Simple Mail Transfer Protocol) : It is the most used protocol for sending emails. It is responsible for transferring the message from the output server to the corresponding input server.
  • POP3 (Post Office Protocol 3 ): It is the most used protocol for receiving emails. It is responsible for downloading the message from the incoming server to the recipient's device. Once downloaded, the message is deleted from the server.
  • IMAP (Internet Message Access Protocol) : It is the most modern and advanced protocol for receiving emails. It is responsible for synchronizing the message between the incoming server and the recipient's device. The message is kept on the server and can be accessed from any device.
