What Formal Letters Test
Formal letters are written to organizations, companies, officials, or people you do not know personally. The examiner is testing whether you can write with complete professional register — no contractions, no casual phrases, precise vocabulary, and a clear formal structure.
The Structure
Salutation: If you know the name use "Dear Mr./Ms. [Surname]," — if not use "Dear Sir or Madam," Note the comma, not a colon.
Opening paragraph: State your purpose immediately and directly. "I am writing to formally complain about..." or "I am writing to express my interest in..." or "I am writing to request information regarding..."
Body paragraphs: One clear point per paragraph. Use formal connectors — "Furthermore", "Moreover", "In addition", "However", "Nevertheless". Each paragraph should build your argument or request logically.
Closing paragraph: State what action you want the reader to take. "I would appreciate a prompt response to this matter." or "I look forward to receiving your confirmation at your earliest convenience."
Sign-off: If you used the person's name use "Yours sincerely," — if you used "Dear Sir or Madam" use "Yours faithfully," This rule is frequently tested and frequently failed.
The Sincerely vs Faithfully Rule
This is one of the most commonly tested details in formal letters. The rule is simple:
Named recipient ? Yours sincerely Unknown recipient (Sir or Madam) ? Yours faithfully
Memorize this. It appears in real IELTS exams regularly.
Formal Vocabulary to Use
Instead of "want" use "wish to" or "would like to". Instead of "get" use "obtain" or "receive". Instead of "ask" use "enquire" or "request". Instead of "fix" use "rectify" or "resolve". Instead of "tell" use "inform" or "notify". Instead of "think" use "believe" or "consider".
Common Mistakes
Using contractions anywhere in a formal letter — "I'm", "don't", "can't" are all unacceptable.
Using "I am writing to tell you about" — too vague. Be specific about your purpose immediately.
Incorrect sign-off — the Sincerely/Faithfully rule is tested and many students fail it.
Passive aggressive tone in complaint letters — be firm and professional, never angry or emotional.
Being too brief — formal letters should be 170-180 words to score well.
Practice Question
You recently purchased a product from an online store and it arrived damaged. Write a formal letter to the company's customer service department. In your letter: describe what you ordered and what the problem was, explain how this has inconvenienced you, and state what action you would like the company to take.
