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.
Example: During the recent ARRGH convention in Washington, D.C., one of your sales representatives, Dusty Brown, informed me of a possible opening for a manager in your Data Center. My extensive background in programming and my master’s degree in information systems make me highly qualified for the position. In subsequent paragraphs, expand on the qualifications you mentioned in your opening. Add any appropriate details, highlighting experience listed on your resume that is especially pertinent to the job you are seeking. Close with a request for an interview. Proofread your letter carefully.
