Signing an Uploaded or Mailed Cover Letter. If you're uploading your cover letter to a job site, your signature will simply include a closing and your full name. Place a comma after your close, such as Best, or Sincerely yours, and then put your name on the line below. When you're sending a written letter include a closing, your handwritten signature, and your typed full name. Leave several spaces between the close and your typed name. That way, you'll have room for your signature when you print out the letter. Sign using either blue or black ink.
If your intent is to persuade the recipient in some way, whether it's to invest money, give you a reference, hire you, partner with you, or fix an issue, create a compelling case for your cause. If, for example, you want the reader to sponsor a charity event, identify any overlap with their company’s philanthropic goals. Convince the reader that helping you would be mutually beneficial, and you will increase your chances of winning their support. Keep your closing paragraph to two sentences. Simply reiterate your reason for writing and thank the reader for considering your request.
