1. The first thing that should be on the page when writing a proposal letter is the address of the sender. Include your address at the upper left corner of the page.
2. The next thing to do is to be sure of the current date and put it below the sender's address.
3. The next thing that should follow is the address of the recipient. Put this directly below the date, but leave like two lines after the date before you write the address of the recipient.
4. Depending on the person you are writing, put the appropriate salutation. You use the word "Dear" together with their title or last name.
5. Depending on whatever you are writing, the body of the letter should be tailored around it, and leave a line before you start a new paragraph.
6. The next thing to do is to write the closing paragraph, after which you add an appropriate closing such as regards, thank you, sincerely, then put your full name below it.
