What Is an Informal Letter and When Should You Write One?

An Informal Letter, also called a personal or friendly letter, is a casual letter written to someone you know well, such as a friend, relative, or neighbor. It uses a relaxed, conversational tone, just like you'd speak in real life. People write informal letters to share news, invite someone to an event, congratulate them, say thanks, or check in after a long time. A handwritten or personal letter feels more meaningful than a quick text, and it shows the reader you truly care.

Write a Warm, Well-Organized Letter Without the Guesswork

Even casual letters need a simple structure so your message flows naturally and is easy to read. Many people aren't sure where to put the address, how to greet the reader, or how to end the letter properly. A ready-made Informal Letter Template already includes the correct layout, from the address and date to the greeting, body, and friendly closing. You just add your own words, so your letter looks neat, feels personal, and says exactly what you want to share.

Teachers can also share it in class as a simple example of how a friendly letter should look.

How to Write an Informal Letter Step by Step

Start by writing your address and the date in the top corner. Greet the reader warmly, such as "Dear Sarah" or "Hi Uncle Tom." In the first paragraph, ask how they are or mention their last message. Use the middle paragraphs to share your main news, story, or reason for writing in a natural, friendly tone. In the final paragraph, wrap things up and invite them to reply. End with a friendly closing, like "Love" or "Best wishes," followed by your name.
