6. Proofreading to Catch Errors After you compose your message, you need to proofread. You don't want to spend a lot of time composing the message and then have the reader misunderstand it because of poor grammar or punctuation. What questions should you ask yourself when proofreading? Check all that apply. Did I consider the recipient's needs and expectations? Did I place a comma before coordinating conjunctions that appear in compound sentences? Did I spell the recipient's name correctly? Should I send a letter or an e-mail?.
