Letter writing remains a fundamental way to communicate, whether for personal or professional purposes. While emails and messages dominate modern communication, knowing how to structure a proper letter is still valuable. Informal formal letter writing helps you express thoughts clearly, whether you are writing to a friend or sending a business request. An informal letter allows for a personal, conversational tone, while a formal letter follows a structured and professional approach. Understanding the key differences ensures that your message is appropriate and effective. Mastering both styles improves communication skills, making written interactions smoother and more impactful in any situation.
Understanding Informal Formal Letter Writing
Informal formal letter writing refers to the skill of crafting both casual and professional letters with the right tone and structure. Informal letters are friendly and relaxed, while formal letters follow a structured, professional format. Knowing when and how to use each style ensures clear, effective communication in personal and business settings.
What Is an Informal Letter?
An informal letter is a personal correspondence sent to friends, family members, or acquaintances. Unlike formal letters, these are relaxed in tone and do not follow strict formatting rules. The main goal is to express emotions, share news, or simply keep in touch.
Purpose of Informal Letters
People write informal letters for several reasons:
- Sharing personal updates or life events.
- Expressing emotions like gratitude, sympathy, or excitement.
- Sending casual invitations or making friendly requests.
- Maintaining relationships with distant friends and family
What Is a Formal Letter?
A formal letter is used for official communication in business, academic, or professional settings. It follows a structured format and maintains a professional tone.
Purpose of Formal Letters
Formal letters serve multiple functions:
- Job applications – Applying for a position.
- Business communication – Engaging with clients or organizations.
- Official requests – Seeking information from authorities.
- Complaint letters – Addressing service-related concerns.
- Recommendation letters – Providing a reference for someone.
Structure Of An Informal Letter

Your address appears at the top right corner. This helps the recipient reply if needed. If writing to close friends or family, this step is optional.
2. Date
The date follows the sender’s address and is formatted as:
January 4, 2025 or 4th January 2025
3. Salutation
Greetings in informal letters are relaxed:

- It’s been a while since we last talked.
- Just wanted to check in and see how things are going.
5. Body
The main section shares thoughts, stories, or updates. The content varies but should remain engaging and natural. Example:
“Last weekend, I visited a new café downtown. The coffee was amazing, and it reminded me of our hangouts. Let’s plan a visit soon!”
6. Conclusion
The closing paragraph includes final thoughts or well wishes:
- Looking forward to catching up soon.
- Give my regards to your family!
- Take care and stay in touch.
