Official Letter vs Informal Letter

Have you ever thought about the differences between informal and formal letters?

An informal letter, or correspondence, is personal and informal. A letter you write to friends or family members is written in a more informal way and a casual structure.

A formal letter is business-like, formal, and official. It is used when at work, for business or official purposes, and is written in a formal structure and polite tone. In brief, formal letters are formal and official, whereas informal letters are personal and friendly, such as thank-you letters.

Knowing when to write each type of letter will help you to get your message across!

Primary Reasons to Write an Official Letter

Dear readers, these letters are not just about what you say, but how you say it. It will help to build trust, demonstrate seriousness, and ensure your message is taken seriously. Here are the main reasons to write official letters:

2. Requesting Permission, Services, or Support

Formal letters can be used when you want permission to do something, want another group or team to help you, or need resources to be authorized for your work. The formal method of requesting such is often through an official letter. The format of formal letters makes sure that your needs are recorded and taken seriously.

3. Filing Complaints or Grievances

When you have a complaint that must be addressed, perhaps a failed service or workplace matter, or even a disagreement over policy, official letters give a framework to express dissatisfaction in a professional manner and request a resolution.

4. Making Job Applications or Quitting a Job

Writing a job acceptance letter, a cover letter, and a resignation letter are typical examples of official letters. They reflect your professionalism and help set the tone for your career-related communications.

5. Official Announcements

Be it updating the stakeholders on a new policy, making an announcement on a new venture, or any other crucial announcement, official letters are formal communications that cannot be ignored easily and are authoritative in nature. An official invitation letter is a common example of this.

9 Awesome & Simple Steps to Writing an Official Letter Guide

Wanted to write an official letter for your upcoming vacation or to HR of your dream company, but don’t know the right process? Don’t worry, we are here for your rescue!

Writing an official letter might be a challenging task, but it can be broken down into manageable portions, which will make the process easy and quick. This is how you can make a clear, professional, and effective official letter:

Step #1. Prepare Your Document.

Start by selecting a neat, professional font, like Arial, Calibri, or Times New Roman. Usually, size 12 Font and consistent spacing make your letter look professional and simple to read. Also, make the margins of your document one inch all around. This not only makes your letter look neat, but it’s also a normal format practice in business.

Step #2. Add Your Address and Date

Now, it is time to add your address. You have to write your complete address. Where? At the upper left side of your document. What to include? This must contain your name, street address, city, state, and zip code. After adding your address, it’s time to add a date. Below your address, write the date of conveying the letter.

Step #3. Add the Details of the Recipient

Now, write the name of the recipient in full, followed by his or her job title, organization, and address below your address and the date. Also, ensure that you check the spelling of names and job titles twice, as these small elements depict respect and professionalism. It also enables your letter to get into the correct hands or department.

Step #4. Put a Formal Salutation

Now, you need to mention a formal salutation at the top of your letter. To do this, the most recommended format is “Dear [Title][Last Name],” such as “Dear Mr. Steve,” or Dear Dr. Petrova, etc. When you are not sure about the name or gender of the recipient, then a greeting that says, Dear Sir/Madam would work here.

Step #5. Add the Subject

On the line immediately after the salutation, write the subject line all in capital letters. This topic line must convey the purpose of the letter in one short line, such as REQUEST LEAVE OF ABSENCE, or APPLICATION Job Vacancy. This line also tells the recipient how urgent your request is, and it serves to preview the content of the letter.

Step #6. It’s Time to Write the Body

The body of your formal letter will enable you to express your major point. You need to break down your letter into 3 logical paragraphs in the following way:

• 1st Paragraph: The first paragraph should clearly address the purpose for writing: plain and simple, direct, and to the point.
• 2nd Paragraph: The second paragraph should provide details, an explanation, or any context needed.
• 3rd Paragraph: The final third paragraph should conclude the message. This can include your request, a summary, or next steps.

Step #7. Add a Professional Signature

Now, it’s time to wrap up your letter with a polite closing word like, sincerely, regards, or respectfully, and then a comma. To do this, add some lines of space (to write your hand signature in case of printing), and type your name in full below. When sending the letter electronically, a typed name is sufficient, but you can add a digital signature for a more professional touch.

Step #8. Add Enclosures (if any)

When you are adding some extra documents (such as forms, resumes, or supporting evidence), note them at the end of your letter in the section of enclosures. For example: Medical Certificate. This is to warn the recipient to be on the lookout for such attachments, and nothing is missed.

Step #9. Proofread

Before posting your letter, take a few minutes to proofread it. Proofread to find mistakes in spelling, grammar, and punctuation. To do this, ensure your letter formatting is smooth and the message is concise.
