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.
You can also include links to online portfolios, if appropriate, or a link to your professional social media account such as LinkedIn or Twitter. You don't want to make this section too cluttered, however, so restrict yourself to the most relevant information. Here's how to set up an email signature, along with more advice on what to include in it and what to leave off.
