Choose an appropriate format for your letter. While there are no hard rules regarding how to structure your letters, many people choose to employ a three-part format. A well-written letter will have a greeting, a body paragraph (or paragraphs), and a closing. For example:[1]

• Start your greeting or salutation at the top of the page with the words, “Dear [pen pal’s name].”
• Next, develop the body of the letter. This is where you'll communicate at length with your pen pal. It can be 2 to 5 paragraphs.
• Finish with a closing. It usually consists of a final paragraph and a signatory phrase like “Sincerely,” followed by your signature.
