SMTP

SMTP, or Simple Mail Transfer Protocol, is the standard technology used to send emails across the internet. Think of it as the postal service for digital messages—it's responsible for delivering your email from your device to the recipient’s email server. When you click send, SMTP handles routing and forwarding your message, ensuring it reaches the right destination. It works behind the scenes, communicating with servers to transfer emails efficiently and securely. Once the email arrives at the recipient's server, they can then retrieve it using other protocols like IMAP or POP3.
