What is email
Email is electronic mail that anyone with email client software or webmail can read and send. The SMTP provider knows where to send the mail via the email address.
For email, as with html, standards are determined that make it look the same in most email programs. An email may contain additional information in addition to the sender,
recipient (s), subject and message. For example, you can indicate whether a message is important or whether you would like to receive a confirmation of receipt. You can also
attach files or send e-mail in html format. Recipients can consist of a main address, a cc (carbon copy) for other addressees, and bcc (blind carbon copy) where other
addressees can not see that the email has been sent to them.
