Business letter format is usually in a block style without indentations. If the letter is not on letterhead, the letter will begin with the name, and address of the letter writer. Skipping two lines, the letter will then have the date of the letter written out. The letter will be formally addressed and the salutation will read " Dear Mr. or Dear Mrs." The body of the letter will follow with
. a closing. For more information and samples visit: http://www.writeexpress.com/business-letter-format.html
