The chosen protocol, SMTP, stands for Simple Mail Transfer Protocol. It is specifically designed for sending emails across the Internet. SMTP works by transferring email messages from a sender's email server to the recipient's email server, ensuring that the messages are delivered efficiently. This protocol is fundamental to email communication because it establishes the rules for how emails are transmitted, making it the primary method used by email clients and servers for sending messages.

In contrast, HTTP (Hypertext Transfer Protocol) is primarily used for transferring web pages and content over the Internet, while FTP (File Transfer Protocol) is used for transferring files between a client and a server. IP (Internet Protocol) is a fundamental networking protocol that handles the addressing and routing of packets of data but does not specifically relate to email sending. Therefore, SMTP is the protocol that is accurately associated with the action of sending email.
