Correct Letter Format
Dear (insert contact and address by title or last name),
This should be an introduction to your letter and you can also introduce yourself in this section if the reader is unlikely to know you.
Here you should go into detail about your subject matter. Take the time to explain why you are writing and indicate what you hope to achieve through your letter.
Here you can reiterate what it is you are trying to say through your letter, and hopefully include a call to action for the person who is reading the letter. Sign off by thanking the reader for his or her time.
