You can either write your cover letter directly in the email message or attach a copy of your cover letter. Either way, it's important to follow the directions in the job posting when emailing your cover letter and resume or your application may not be considered.
First, open your email account. Then click on Message at the top left of the screen or click on File, New, Message.
You can either type your cover letter directly into the email message, copy and paste from a word processing document, or, if the company requests an attachment, send your cover letter with the email message.
Be brief and to the point. Your email cover letter should not be any longer than two or three short paragraphs.
