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.
Then you arouse their desire by explaining how you can do this — for instance, by showing how successful you’ve been in other positions, or by explaining the specialized training you have relevant to the job. Avoid jargon here — explain clearly and concisely the benefits of the solution you offer. When I worked in marketing, I learned an important lesson: nobody buys anything based on features (and “buy” is used in its loosest possible sense, like you “buy” an idea). You have to explain exactly how those features will benefit the potential buyer.
