Formatting Business Email
The format of business email is very similar to that of a business memo. So similar, in fact, that the basic heading elements found in a business memo are programmed into the computer generated template of every email program. The communication role of business email goes beyond that of a memo, however. In order not to overlook its versatility, the formatting elements of a business letter can be inserted manually into the body of an email.
Business email functions as both an internal and an external method of communication; its three main formatting elements are the heading, the body, and a signature block. Depending upon the nature of its correspondence and, at the discretion of the writer, business email may also include a salutation and a complimentary close.
