When your letter is to more than one person, write out all of their names separately, separating them with commas. For example, "Dear Mr. Hobbes, Ms. Luxe, and Mr. Hopman." For married couples, if one person in the couple has changed his or her name, you only need to use the last name once. For instance, "Dear Mr. and Mrs. Smith."
Signature Examples for Emailed Documents. When you are sending email cover letters, it's important to include contact information so the hiring manager can easily see how to contact you. At the very least, include your name, email address, and phone number. You can also add other, optional information, such as your street address, online portfolio, or social media accounts.
