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.
While a simple "Hi," "Hello," or even "Hey" is appropriate in casual correspondence, a more formal salutation is appropriate when you are emailing about a business_related matter, such as a cover letter, letter of recommendation, or inquiry letter.
