How to format a cover letter

Type each letter individually, or use a word processor.
Use good quality bond paper.
Whenever possible, address each employer by name and title.
Each letter should be grammatically correct, properly punctuated, and perfectly spelled. It also should be immaculately clean and free of errors. Proofread carefully!
Use conventional business correspondence form. If you are not certain of how to do this, ask for help at the Writing Center.
