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.
If you are writing to someone who has a doctorate or medical degree, use the abbreviated form: "Dr." However, for other titles, such as professor, judge, rabbi, etc., write out the full title and capitalize it. For example, your salutation in a letter to a judge would be, "Dear Judge Barnard." Or, if your correspondence was with a rabbi, you might write, "Dear Rabbi Williams."
