Humans can communicate in multiple languages, not just through speech, but also with gestures and expressions. But what sets us apart is our ability to write. Writing and reading have become an integral part of our daily lives within the first few decades of a person’s life.

Writing has been a common skill for humans. Messages are an important and constantly evolving form of communication between humans. Around 500 BC, Atossa, a Persian queen, wrote the first handwritten letter.

Informal Letter Writing

The communication industry has seen a boom, allowing for groundbreaking inventions that allow fast messaging. Many people believe that email, text messaging, and video calling have eventually replaced the need to write letters. But is it?

Moreover, what is the reason our ancestors started writing letters? Since the ‘Before Common Era,’ letters have been part of our society. They dominated long-distance communication up until Alexander Graham Bell invents the telephone in the latter half of the 19th century.

Even though this breakthrough was significant, the telephone underwent many changes before becoming a household name in the latter half of the 20th century. The letters have also been an invaluable source of information for unravelling history.

To understand the political relationships between states and kingdoms, and to discover the undiscovered scientific discoveries and inventions, historians have used recovered correspondence. These letters help us to understand how languages, as well as cultures, have developed and changed.

Who and What?

These points can be thought of as two sides to a coin. Undoubtedly, these letters should be personal and addressed to someone you are familiar with. Think about the question “Why?” and what you are trying to convey to them. Before you write, think about these questions.


You can use any lingo too. You can use short forms, spelling modifications, and also bilingual words. Don’t worry about technicalities or strict grammar rules if you aren’t writing an informal letter to an exam. An informal letter writing, emotion is more important than grammar rules. This brings us to the final point.

There is no standard format for informal letters. There is however a pattern or convention that most people follow. This pattern will also be discussed along with some tips for writing effective and appealing informal letters. These guidelines can be used as a guideline when writing a letter. They aren’t hard and fast rules.


Your address is the first thing you should write. The address of the writer ( basically the sender’s address). It is usually written on the left-hand margin of the page, at the top. The address must be correct and complete.

You must give the address to your family members and friends, even if you are writing to them. This will allow them to reply to your letter quickly. Do not forget to include your country if the recipient is from another country.


The date is next, just below the address. This gives the reader a date so that he can refer to the informal letter. This allows him to better relate to the contents of his letter. It is preferable to include the date in an expanded form.


Since you already know the person you’re writing to, you can make the greeting informal. You can use your first name to greet a friend or relative, such as ” Dear Alex”.

If you are writing to your relatives like your mother/father/aunt/uncle etc, you may greet them as such, for example, “Dear Mom”. And if you are writing to an elder person, someone you respect greatly you can address them as Mr or Mrs Like say for example you were writing a congratulatory letter to your teacher, it can be addressed as “Dear Mrs Alex”.

Introduction Paragraph

You might also say that you wish the recipient is in great health and spirits. You should make informal letters feel comfortable and casual when opening them. It should also not be as formal and direct as in business letters.

The Body of the Letter

You should keep the tone of your letter friendly. However, you need to adapt the language and wordings to the recipient. You can be casual and even sarcastic with a friend. However, if you’re writing to an elderly relative, be respectful and considerate.

To determine the tone of your letter, you can refer to how you speak to that person during a conversation. Then, apply the same syntax to the letter.

Formatting Your Letter

Notify us of your address and the date (optional). Place your current location on a piece of paper in the upper lefthand corner. Record the date and month in the upper left-hand corner of a clean sheet of paper or new word processor document.

  • You can spell the date in full (“Wednesday, February 12, 2018”) or you can use the abbreviated numeral (“2/12/18”) to keep it simple.
  • These details are a great way to tell your recipient when and where you wrote the letter. This is especially helpful if you live in different parts.

Inscribe the name of your recipient At the top of each letter Begin your letter with the name of the recipient. The opening address is traditionally located in the upper lefthand corner of the page. However, you can place it wherever you like, as long as there’s enough space to include your message below it.

  • You can also add a salutation to the recipient’s name if you wish, such as “Dear,” or “My darling,” but you don’t have to.
  • If you are writing an open letter but don’t know who the recipient is, begin with a general address such as “To whom it may concern” and “To anyone who reads this letter.”

Send your message in the body of the letter You can also use the space below your recipient’s name for anything you wish to say. You can make your letter as long as you like.

  • Let your heart swell! You can either start over on the first page or flip the paper and write on the back.
  • You can keep your handwriting organized by using lined paper such as a notebook or journal paper.

To close the letter, write a brief closing. After you have communicated your message in the body, make sure to leave some space (about one line) below the last sentence for a sign-off. 

  • You might use the following closing line: “Sincerely,” or “Yours truly”Your recipient will know when the letter is finished by closing.
  • You don’t need to send a formal letter. If you don’t wish to, you can also just sign off with your name.

Tip: Write a closing that best reflects the reason you are writing. For example, a letter of condolence could be ended with “My deepest sympathy.”

Please sign your name at bottom of the letter. If you have included a closing line, place your name there. This will act as a lead-in to your signature. It’s possible to sign your name in cursive, formal script, or both. However, it is also acceptable to print it or type it.

  • Depending on how familiar you are with the person to whom you’re writing, you might also use your full name or your first name.

Add Some Style

1. For a more human feel, keep your language conversational Informal letters should be read casually and in a relaxed manner. You are free to use contractions and hypothetical questions as well as inside jokes and other figures. This will allow your natural voice to be heard by your reader.

  • It can help to think of a conversation you are having with a friend, and then write what you would say.

Tip A good tip is to start your letter off with this: “Hello bestie!” It’s amazing how fast time goes! We’re running after boys at summer camp one minute, then the next we’re getting married. It’s weird to be an adult!

Spice Up Correspondence

To spice up your correspondence, use coloured inks or fonts. For newspapers and formal letters, black ink is best. Use your brightest pens to add some personality to the page. If you are writing to a friend, bright colours like red, green, and red can be great attention grabbers.

  • Mixing colors can also be a great way of breaking up the monotony and highlighting keywords or phrases.
  • The color you choose must be visible on both sides of your letter paper. Your message might not be easy to read if it isn’t.

To add a visual flair, draw in the margins of handwritten correspondence. You can also use the extra space to fill it with symbols, doodles, and other quirky notes. These elements will let you express your creativity and give the reader something to look at.

  • An artist’s rendition of Bigfoot might be a good way to spice up your story about the time you saw him at the mall.
  • You could also make a joke of a typo you find in a letter by writing, “I swear I can spell!” beside it.

Mailing Your Letter

Fold your letter Double it vertically to ensure that it fits in an envelope. You need to fold the letter paper at 1/3 to the top. Fold the doubled section one more time. This will create a neat piece that can be folded in any business envelope.

  • This method works best when used with standard 8.5 inches (22 cm) x11 inches (28 cm), printer paper. However, you can also use it to fold other sizes of paper.

Put your letter into an envelope and seal it. To ensure that your letter fits in the envelope, place it widthwise. To finally 6seal the envelope, you can lick the glue strip at the inner edge of it to moisten it. Next, lower the flap by applying gentle pressure for a few seconds until the adhesive sticks.

  • You should keep in mind that envelopes can come in many sizes and shapes. Try shopping around to find a better-fitting envelope if you have trouble fitting your letter into a standard business envelope.

Tip To ensure your envelope stays closed, you can use a cotton swab or a damp sponge to keep it from getting rubbed.


Print the mailing address of your recipient On the envelope’s face Write the name of the person, along with their last name and full address, in the middle of the envelope. Also, include the city, state, or province where they reside.

  • If your recipient does not live in a home, make sure to add an apartment number.
  • You can write your address in the upper righthand corner of the envelope if you want to let the recipient know who sent it.

Place a stamp in the upper right corner of the envelope Place your stamp right across from the return address so that it is easily visible by your mail carrier. After you have added the correct postage to the letter, you can drop it in the mail and send it to your recipient. 

  • How Many Stamps Are Required Most letters larger than 1 oz need one stamp unless they have an unusual shape or are not uniformly thick?
  • Postage should not be attached in the upper-righthand corner. This could confuse the sorting machine at your local post office. Your might get your letter back in some cases.
