Techopedia Explains Electronic Mail

Email messages are relayed through email servers, which are provided by all Internet service providers (ISP).

Emails are transmitted between two dedicated server folders: sender and recipient. A sender saves, sends or forwards email messages, whereas a recipient reads or downloads emails by accessing an email server.

Email messages are comprised of three components, as follows:

  • Message envelope: Describes the email’s electronic format
  • Message header: Includes sender/recipient information and email subject line
  • Message body: Includes text, image and file attachments
