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.
For instance, in a typical job application, the problem is that the company or organization needs a position filled, and more importantly they need someone who can do the job well and help the organization achieve its mission (which may be more profits, or it may be to save children in Darfur or to end global warming or to cure cancer). You arouse their interest by telling them that you’re the right person for the position and by promising to help them achieve their mission.
