How to Sign a Cover Letter with Signature Examples. When writing a cover letter to include with your resume, it's important to pay attention to every detail, since you only get one chance to make that first impression. So, what exactly should you include in your signature when you're writing your cover letter to apply for a job? It varies, depending on how you apply for the position. The format and information included in your signature changes depending on whether you are mailing, uploading or emailing your cover letter document.
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."
