Students often write informal letters to share news, congratulate someone, invite friends to events, describe experiences, or maintain personal connections with loved ones.

What Is an Informal Letter?

Informal letter writing is the type of writing whereby an individual writes to another individual with whom he/she has a personal relationship. Informal letters are mostly used to exchange information, congratulate, invite, or communicate other personal issues.

• Expressing feelings and emotions

The main objective is to make personal communication with the recipient.

Format of an Informal Letter

Letter writing is a very flexible process; nonetheless, there are certain elements that are present in a letter that make it an effective form of communication. Understanding of these elements is important for successful letter writing. 

Sender’s Address

The sender’s address is normally placed at the top left-hand corner of the letter. This is done so that the recipient knows where the letter originates.

Date

The date of writing the letter is written immediately after the name and address of the sender.

Salutation

Salutation refers to the manner in which the addressee is addressed.

Common examples include:

• Dear Rahul,
• Dear Friend,
• Dear Mom,
• Dear Uncle,

Salutation should reflect the kind of relationship that exists between sender & receiver. 

Introduction

It proved to be a pretty enjoyable as well as refreshing experience. I shot a lot of pictures, and also got to know a lot about the culture there. I wish you were there too; it would have made it even more fun.

Main Body

The body paragraph includes a critical point to make by the person who wrote it. This could include anything from experience sharing, inviting, congratulating, giving advice, and much more.

Conclusion

The conclusion should consist of a summary of the letter and end on a positive note. Many letters normally conclude with an anticipation from the sender of receiving replies from the addressees.

Closing

Some examples of closing lines in an informal letter include:

• Yours lovingly,
• Yours affectionately,
• Best wishes,
• With love,
• Your friend,

The writer’s name follows the closing.

How to Write an Effective Informal Letter

In addition to knowing how to write an informal letter, one has to know what goes into making a good one. In order to do that, one has to consider their purpose for sending such a letter.

Use a Friendly Tone

Formal letters must adopt the correct tone and style. Address your correspondent as if you were talking to him or her.

Keep the Language Simple

Do not use any difficult terms and jargon while writing. Simpler language helps make the letter more approachable.

Stay Organized

Structure your ideas in a logical manner. Write an introduction, state your ideas in the body section, and end your composition with a clear conclusion.

Show Genuine Emotion

Informal letters are inherently personal. Be honest when expressing feelings while writing about an experience, conveying your congratulations, saying thank you or giving any kind of advice.

Be Clear and Concise

Informal letters can be very informal, but need to communicate ideas clearly. Unnecessary repetitions are not required in such a letter.

Example of an Informal Letter

Letter to a Friend Describing a Holiday

Dear Aman,

I hope that you are doing well. We haven’t talked for a very long time now; therefore, I decided to write to you regarding my latest vacation.

During this summer season, I, along with my family members went on a visit to Manali. It was wonderful weather with great scenery of the mountains. Apart from sightseeing and exploring the local cuisine, we also engaged in various kinds of adventure sports. The visit to Solang Valley is one of the best things that I remember.

It was a refreshing as well as adventurous experience for me. In addition, I clicked some photos and gathered knowledge about the culture prevailing in that region. Unfortunately, you were not with us on this tour; otherwise, it would have been even better.

Let’s arrange to meet as soon as possible.

Yours affectionately,

Rohan
