Step 2: Write the salutation

Just like formal letters, informal letters start with a polite greeting to the recipient. The standard format is the same: the word “Dear” followed by the person’s name, as in “Dear Mr. Lestrade,” using title capitalization. 

However, informal letters provide more freedom when it comes to what you say in your greeting, and it’s not uncommon to see casual greetings like, “Hi [Name],” or “Hello [Name].” 

As with salutations in formal letters, you normally end your greeting with a comma and then skip a line before beginning the body of the letter. Occasionally you see people end the salutation with an exclamation point, although it depends on their relationship with the recipient. 

Step 3: Write the body of the letter

The body of the letter is where you write your message, and informal letters are often meant to share news or keep in touch. They tend to have a conversational tone, which means you’re free to include slang and whatever language you use when speaking in person. 

While tangents are more permissible in informal letters, going off topic excessively can still bother the reader. Try to stay focused as best you can without sounding restrained—informal letters are supposed to be personal, after all. 

Step 4: Write the complimentary close

Informal letters also use a complimentary close before the signature, following the same format as formal letters. That includes using sentence capitalization (capitalizing only the first letter), adding a comma at the end, and leaving enough space to sign your name if you’re sending a paper letter. 

However, you don’t need to stick with the conventional sign-offs like “Sincerely.” If you’re writing a personal letter, you can use something more sentimental depending on the relationship with the recipient, such as “Love,” “Warm regards,” or “See you soon.”
