As far as formatting, your cover letter should follow the same basic rules as any other business letter. This means it needs to open with a courteous salutation, contain three paragraphs, and have a handwritten signature at the end. This cover letter format
looks best when typed out. It is always better to send a digital cover letter over a handwritten one. The only part of your cover letter you should write by hand is your signature. The end of your cover letter should contain a closing, such as "Sincerely" or "Best Regards." You need to follow this with your signature and then your name printed out normally. When writing your signature, you should only use black or blue ink. If you need to send your application over email, then you will need to then scan the document so that you can send it back electronically. When providing your signature, make sure to use your professional name. Therefore, if your resume has your name as "Michael Hughes," then you would not want to provide your signature as "Mike Hughes."
