Describe the structure of a typical email message,including the two main areas of the message and the components of each of those areas.

An email message typically is organized into two areas: the message header and the message area.
The message header contains:
•the email address of the recipient(s),the primary person or persons to whom you are sending the message;
•an optional courtesy copy or carbon copy (cc),which includes one or more additional recipients;
•the subject line,which states the purpose for the message.
The message area consists of:
•a greeting line or salutation that sets the tone of the message and can be formal or informal,depending on the nature of the message;
•the message text,which informs the recipient or summarizes or requests information;
•an optional closing that signals an end to the message using courtesy words such as Thank you or Regards;
•a signature that identifies the sender and may contain additional information,such as a job title and phone number(s).In a signature,the name usually is provided on one line followed by other information listed on separate lines.
