What Is an Informal Letter?

Informal letter is a personal letter addressed to a person you know well and have written to before, like a friend, cousin, sibling or parent. It’s written in a relaxed, everyday style of language like you would use in a conversation.
The main difference between informal and formal letter is the tone of the letter. A formal letter is written in a business context, to apply for a job, or to make an official request, and must be polite and well-structured. A letter, however, that is informal is relaxed and personal. No need to worry about sounding “professional” when sharing jokes, discussing with the family or talking about everyday life.

Typically, this style of letter is used when an individual wants to convey good news, invite someone to an event, inquire about the health of a person, or simply stay in touch when unable to meet in person.

c An Informal Letter (Step By Step)

Step 1: Start with a Warm Greeting

The first line of the letter creates the tone. The greeting must be simple and friendly since you are writing to someone who is familiar to you. You could use:

Hi [Name],
Hello [Name],
Dear [Name],
Hey [Name],

Opening the letter with “Hey Maya, how have you been?” makes it feel very personal and heartfelt.

Step 2: Write the Personal Email Message

Following the greeting, include a line that demonstrates that you are really considering the person. This makes the letter appear more sincere as opposed to hurried. Some useful phrases:

Hope that you are doing well!
I have been coming up with ideas for writing to you.
I’m sending you a quick email.
It has been long time since we spoke!

Step 3: Share Your Message or Updates

This is the body of the letter, where you discuss the purpose of your letter. It might be news, invitation, question or status updates. Avoid using long, formal sentences; write as you would speak. To connect your ideas together, you can use the following transitions:

By the way…
Guess what?
What a thing to happen, you won’t believe me!
I wanted to let you know that…

Step 4: Close Warmly

Close the letter in a friendly manner that will make the reader feel good and excited to respond. Typical closing statements are:

Take care,
Lots of love,
Best wishes,
Talk soon,
In anticipation of your reply,
