Contact Information: The first section of your letter should include your contact information and the contact information of the person you are writing, too. Also, include the date you are writing at the top of your letter. Letter Salutation: Unless you know the reader well and typically address them by their first name, you should include the person's personal title and full name in the salutation (i.e., "Dear Mr. James Franklin"). If you are unsure of the reader's name, include his or her title (i.e., "Dear Executive of Marketing"). If you are unsure of the reader's gender, simply state their full name and avoid the personal title (i.e., "Dear Jamie Smith"). If you are unsure of the reader's gender, name, and title, simply write, "To Whom It May Concern." Leave one line blank after the salutation.
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.
