Closing: When you're writing a business letter or email message it's important to close your letter in a professional manner, so you're letter, in its entirety, is well_written and professional. Signature: When you are sending a paper letter, finish the letter with your signature, handwritten, followed by your typed name. If this is an email, simply include your typed name. Finally, don't forget to spell check and proofread your letter before you send it. Again, ask a family member, friend or colleague to review it for you. It's always good for another pair of eyes to take a look because it's hard to catch our own mistakes.
When you write a business document, you must assume that your audience has limited time in which to read it and is likely to skim. Your readers have an interest in what you say insofar as it affects their working world. They want to know the “bottom line”: the point you are making about a situation or problem and how they should respond.
