IELTS Writing Task 1 Letter Greeting Checker: Formal vs. Informal Salutations

Here's the thing: you can write a brilliant letter body, but if you mess up the greeting, the examiner notices immediately. It's one of the first signals about whether you understand register, and on IELTS General Training, nailing this matters more than you think.

Most students overthink letter openings or, worse, ignore them entirely. You'll sit down, write "Dear Sir/Madam," and assume you're done. But the greeting does heavy lifting. It sets tone, demonstrates control of formality, and directly affects your Coherence & Cohesion band score. Get it wrong, and you're already climbing out of a hole.

Let's fix this. By the end of this post, you'll know exactly which greetings work for which situations, why some openings tank your score, and how to spot the difference in 30 seconds.

Why Your IELTS Task 1 Letter Greeting Matters More Than You Think

IELTS Writing Task 1 is worth 33% of your overall writing score on General Training. That's not trivial. Within that task, register and tone are assessed under the Coherence & Cohesion band descriptor, which explicitly mentions "appropriate register throughout."

An incorrect greeting signals poor register control right away. You're telling the examiner: "I don't know who I'm writing to, or I don't care." That's a confidence killer. Examiners are trained to spot mismatched formality across a piece, and they start noticing in line one.

Formal Salutations: When and How to Use Them

Formal greetings apply when you're writing to someone you don't know, to an authority figure, or to handle a serious matter like a complaint or formal request.

The safest formal options are these:

• Dear Sir or Madam, (when you don't know the recipient's gender or name)
• Dear Mr/Ms [Surname], (when you know the name and gender)
• Dear [Full Name], (less common, but acceptable)

That's it. Don't invent variations. Examiners expect predictability in formal letters. Your job isn't to be creative; it's to be correct.

Why is the second one weak? You don't know the person's actual title or name. "Manager" feels assumed and presumptuous. Stick with "Sir or Madam" when you're genuinely uncertain.

One more rule: never use a colon after formal greetings in British English (which IELTS uses). Write "Dear Sir or Madam," with a comma, then start your next line fresh. Some students add a colon, which is American style and marks them as non-standard immediately.

Informal Salutations: Recognizing When Letters Get Casual

Informal greetings happen when you're writing to a friend, family member, or someone you know well. On IELTS General Training Task 1, this is less common than formal letters, but you'll see it.

Your options here have more flexibility:

• Dear [First Name], (safe middle ground for semi-formal acquaintances)
• Hi [First Name], (casual, for friends)
• Hello [First Name], (friendly, but still appropriate for a letter)

Skip "Hey" or "Yo" or any other slang. You're writing an IELTS letter, not a text message. The bar for "informal" is "warm but still literate."

The weak version isn't actually a greeting problem; it's a register collapse. The greeting starts fine, but the sentence that follows spirals into slang. Once you pick informal, the whole letter needs to stay consistently warm but grammatically solid.

The Biggest Greeting Mistake: Mismatched Formality Levels

Let me be blunt. This is where most students mess up.

You write a formal greeting, then your body suddenly turns casual. Or vice versa. Your opening says "Dear Sir or Madam" (formal), then sentence two reads "I really need your help because this situation is killing me" (informal). That's a register shift, and examiners flag it immediately under Coherence & Cohesion when checking your IELTS writing correction.

Both are complaints. The weak version uses "rubbish" and "ASAP" after a formal greeting, which screams inconsistency. The good version maintains formality throughout. The greeting sets the tone; your job is to honor that tone for the entire letter.

Real IELTS General Training Letter Scenarios and Matching Greetings

Let's walk through three actual Task 1 scenarios you might see, so you know exactly which greeting fits.

Scenario 1: Complaint Letter to a Company

You stayed at a hotel and had a terrible experience. You're writing to the manager.

Greeting: "Dear Sir or Madam," (You don't know the manager's name.)

Why: The letter is formal, addressing an unknown authority figure. You need register to stay formal throughout. If you're unsure about formality levels, our guide on letter tone and register breaks down exactly how to maintain consistency from greeting to closing.

Scenario 2: Thank-You Letter to a Friend

Your friend's family hosted you during a visit, and you want to say thanks.

Greeting: "Dear [First Name]," or "Hi [First Name]," (You know them well.)

Why: This is personal and warm. Informal is appropriate. But keep the letter grammatically polished, not sloppy.

Scenario 3: Request for Information to an Unknown Official

You're writing to a local government office asking about visa procedures.

Greeting: "Dear Sir or Madam," (Unknown recipient, official context.)

Why: You're requesting information from an authority. Formality keeps your request credible and respectful.

Notice a pattern? Formal greetings almost always apply on IELTS unless you explicitly know the person. When in doubt, go formal. You can't go wrong with "Dear Sir or Madam" on an exam.

Common IELTS Letter Greeting Mistakes to Avoid

Here are the errors that instantly drop your score:

• Dear to Whom It May Concern: This is American, stiff, and outdated. IELTS expects British English. Use "Dear Sir or Madam" instead.
• Dear Sir: Incomplete. How do you know the recipient isn't female? Always include "or Madam."
• To the Manager: This isn't a greeting; it's a label. Not acceptable as a letter opening.
• Dear All: Too casual for formal contexts and confusing (are you writing to one person or multiple?). Avoid.
• Hello Sir or Madam: Mixes formality levels. "Hello" is warmer than "Dear," creating inconsistency. Pick one tone and stick with it.
• Dear [First Name]: Used in a formal complaint or business request. This is too familiar. Save first names for people you actually know.

Each of these errors suggests either carelessness or a misunderstanding of register. On a 9-band scale, this kind of error can cost you 0.5 to 1 full band in Coherence & Cohesion. For a deeper dive into common formality mistakes, check our breakdown on IELTS formal and informal letter recognition.

How to Match Your Greeting to Your Letter Closing

Your closing should match your greeting. This is automatic, but students forget it constantly.

If you open with "Dear Sir or Madam," close with "Yours faithfully," (British) or "Sincerely," (American, but acceptable). If you open with "Dear [First Name]," close with "Best regards," or "Warm wishes," or even "Cheers,". The pair should feel like they belong together.

Mismatched greeting and closing feels jarring, like you switched personalities mid-letter. It weakens your Coherence & Cohesion score because the letter no longer feels like one unified piece.

The formal greeting demands a formal closing. The moment you mix them, register collapses.

How to Choose Your Letter Greeting in 30 Seconds

Before you write, ask yourself three questions:

1. Do I know this person's name? If yes, you can use it. If no, use "Sir or Madam."
2. Is this a personal or official context? Personal = informal greeting. Official/unknown = formal greeting.
3. Would I be nervous meeting this person? Nervous = formal. Comfortable = informal.

Answer all three, and your greeting picks itself. This logic works for 95% of IELTS letters you'll encounter.

Write it down. Check it. Move on. Don't second-guess yourself once you've chosen a greeting, because that's when mistakes happen.
