What does E-mail mean?

Email, or electronic mail, is a way of sending and receiving digital messages over the internet or another computer network. A message is sent to a specific email address and, in addition to text, can contain images, documents, links or other attachments. Email is used for personal and business communication, and in e-commerce also for order confirmations, delivery updates, customer support or marketing campaigns. The SMTP protocol is commonly used to transfer messages between servers, while IMAP or POP3 are used to retrieve them. Email is one of the basic tools of digital communication.
