1. Write your name and contact information

In the upper left-hand corner of the letter, include your name or your company's name. Follow it with your address in the lines below.

2. Include the date

Next, make sure to include the date of the letter in the upper left-hand corner. In a block style letter, include a space or line between the date and your contact information.

Use a colon after this and add two hard returns before the next step. Omit this step if you're using AMS style.

Next, write the body of your letter. This section is typically two or three paragraphs in length. Introduce yourself and state the purpose of your letter in the first paragraph. It's important to quickly engage them and be direct with your language. Your second paragraph should be used to underline the message you're sending. Use your last paragraph to summarize the purpose of your letter and how you want to proceed.
