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.
If your intent is to persuade the recipient in some way, whether it's to invest money, give you a reference, hire you, partner with you, or fix an issue, create a compelling case for your cause. If, for example, you want the reader to sponsor a charity event, identify any overlap with their company’s philanthropic goals. Convince the reader that helping you would be mutually beneficial, and you will increase your chances of winning their support. Keep your closing paragraph to two sentences. Simply reiterate your reason for writing and thank the reader for considering your request.
