If a letter necessitates a second page (or, in rare situations, more), always include at least two lines of body text on that page. For the second page, use plain (non-letterhead) paper of comparable quality to the letterhead stationery. Place the header in the upper left-hand corner of the page or across the top. Include your name and address within the header if possible. In most cases, it is not necessary to print the return address on letterhead. If you would like to include your return address, however, you can do so by printing it on the envelope used for mailing. Be sure to write legibly, especially if you have trouble with spelling or punctuation. It is acceptable to print the date on which you mailed the letter near the top of the first page of an email. In this case, "date" should be printed in boldface type. You do not need to include a salutation in your email; simply write your message in the body of the email and sign it. If you prefer, you can print a subject line above your message. This helps people identify important messages easily. When you send a fax, you must include a cover sheet containing the transmission source's name and address along with the complete document number. The cover sheet does not have to be printed, but it must be included with the fax transmission.
