electronic mail uses which application layer protocol?

Electronic Mail Protocol at Application Layer

Answer:
Electronic mail, commonly known as email, uses the Application Layer protocol called the Simple Mail Transfer Protocol (SMTP). SMTP is the standard protocol for sending and receiving emails on the Internet. It works in conjunction with other protocols like Post Office Protocol version 3 (POP3) or Internet Message Access Protocol (IMAP) which are used to retrieve emails from a mail server. SMTP is responsible for sending outgoing emails from the sender’s email client to the recipient’s email server.
