Compose an email message by logging in to the email client with which you has an account, and clicking on the Compose Message or Write Message button. The recipient's email address, the subject of the message and the message body are necessary fields to complete in composing an e-mail message.
Depending on the type of editor used by the email client, the message can be formatted and the text enriched or highlighted. All email service providers allow users to attach files up to a certain size with each email message. These files could be text or graphics. If an email message is partially composed and requires further information before it is sent, it can be saved as a draft for future editing.
