Tips and Tricks for Better Letters: Following the proper formatting is only the first part of writing a letter that gets action. The content of a poorly formatted letter is unlikely to be read _ in one study of HR personnel, more than 80% said they’d throw out a resume if there were only one or two errors in the cover letter _ but even a well_formed letter is unlikely to be acted on unless the content is powerful and engaging. Once you have their attention, you need to create interest in whatever you’re offering. Promise to solve their problems _ with a great product, with your services, with a partnership, with whatever it is you’re writing about.
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.
