Here's what examiners see constantly: candidates who nail their body paragraphs but blow the whole letter because of one mistake in the opening line. A misplaced comma. A capitalization slip. A greeting that can't decide if it's formal or casual. These aren't small things. They're automatic deductions under Coherence & Cohesion, and they tell the examiner you don't actually know formal English conventions.
This is where most students crash and burn. You spend 15 minutes perfecting your complaint letter, then write "Dear Sir/Madam," without understanding why that exact punctuation matters or what happens when you use "Hi there" instead. The gap between Band 6 and Band 7 often comes down to these technical details nobody talks about.
Your greeting and closing are the first and last things the examiner reads. They set the entire tone. Get them wrong, and you're starting in a hole you can't dig out of. This is exactly what an IELTS writing checker catches automatically—but understanding why matters more than the tool.
IELTS Task 1 formal letters get graded on four criteria: Task Response (did you answer the prompt?), Coherence & Cohesion (is it organized and connected?), Lexical Resource (vocabulary), and Grammatical Range & Accuracy (grammar). Your salutation and closing don't exist in a vacuum. They're part of the Coherence & Cohesion score, which accounts for 25% of your writing band score.
An examiner catches you writing "Dear Sir or Madam" instead of "Dear Sir/Madam." It signals carelessness. When you end with "Looking forward to hearing from you, Yours sincerely," the comma placement is wrong, and that's a grammatical error. These details pile up fast across 150 words.
The IELTS band descriptors for Band 7+ explicitly require "coherent use of paragraphing" and "logically sequenced information." Proper letter format supports both. A sloppy greeting or closing breaks that logic immediately.
You don't need to invent creative greetings. IELTS formal letters require one of six standard openings. Pick based on whether you know the recipient's name. When you use the correct salutation with proper punctuation, your letter starts strong.
When you know the recipient's name:
When you don't know the recipient's name:
That's it. Not "Hi," not "Hello there," not "Good morning." Examiners expect one of these six. Anything else gets marked as inappropriate register, which tanks your Lexical Resource score immediately.
Good: Dear Mr. Patel,
I am writing to express my concern regarding the delayed delivery of my order.
Weak: Hi Mr. Patel!
I am writing to express my concern regarding the delayed delivery of my order.
Both convey the same information. One lands Band 7. The other lands Band 5. The only difference is two words.
About 30% of submitted Task 1 letters have these errors. They're fixable, but you need to know what to avoid.
Mistake 1: Wrong punctuation after the name.
Weak: Dear Mr. Johnson. (period instead of comma)
Dear Mr. Johnson: (colon, more American legal style)
Good: Dear Mr. Johnson, (comma, standard British English)
IELTS uses British English conventions. British formal letters always end the salutation with a comma. American style sometimes uses a colon. Stick with the comma.
Mistake 2: Capitalizing the first word of the body sentence incorrectly.
Weak: Dear Sir/Madam,
i am writing to you about...
Good: Dear Sir/Madam,
I am writing to you about...
Your first sentence after the salutation always starts with a capital letter. No exceptions. This is a grammatical accuracy issue and tanks your grammar score.
Mistake 3: Using "Sir/Madam" without the slash or "and."
Weak: Dear Sir, Madam, (incorrect punctuation)
Dear Sir/Madam (this works, but...)
Good: Dear Sir/Madam,
Dear Sir or Madam, (also acceptable)
Both "Dear Sir/Madam," and "Dear Sir or Madam," are correct. Pick one and stick with it. Don't mix formats within the same letter.
Here's the rule that actually matters: your closing line must match your opening in formality level. Named opening gets one closing. Unknown recipient gets another.
When you opened with a specific name (Dear Mr. Khan, Dear Ms. Lopez,):
When you opened with Sir/Madam or To Whom It May Concern:
Not "Yours truly," not "Best regards," not "Thank you." Those are modern, casual, or American business style. IELTS expects one of these three closings, paired correctly with your opening. This distinction matters because examiners check it. It's a coherence issue. A mismatched closing signals you don't understand formal letter structure.
Good pairing:
Dear Mr. Rodriguez,
[letter body]
Yours sincerely,
John Smith
Weak pairing:
Dear Sir/Madam,
[letter body]
Yours sincerely,
John Smith
(Should be "Yours faithfully" after Sir/Madam)
Your closing line has three parts: the sign-off phrase, a comma, and your name. Most students get the sign-off right but destroy the comma placement.
The correct structure:
Good: Yours sincerely,
Catherine White
That comma after "Yours sincerely" is mandatory. It's not optional. It's part of the grammatical accuracy criterion.
Common mistakes:
Weak: Yours sincerely (missing comma)
Yours sincerely;
Yours sincerely.
Yours, sincerely, (wrong placement)
You've probably seen "Yours sincerely" without a comma in emails. That's fine for texting. Not fine for IELTS. The formal letter format requires it. Every single time.
Tip: Formal English separates the closing phrase from the name with a comma. No commas, no formal letter. That's the rule.
Let's walk through two real scenarios you'll likely see on test day.
Scenario 1: Complaint about a faulty product (you know the manager's name from the instructions).
Good: Dear Mr. Thompson,
I am writing to complain about the defective laptop I purchased from your store last week. The device stopped functioning after two days, and I haven't received a replacement or refund despite submitting a claim five days ago.
I'd appreciate your immediate attention to this matter and expect a resolution within seven days.
Yours sincerely,
David Chen
Scenario 2: Inquiry to a university admission office (no specific name given).
Good: Dear Sir/Madam,
I am writing to inquire about the application process for your postgraduate management program. I'd like to know the specific requirements for international applicants and the deadline for the next intake.
I'd be grateful if you could provide this information at your earliest convenience.
Yours faithfully,
Maria Rodriguez
Notice the differences. Scenario 1 uses a name, so the closing is "Yours sincerely." Scenario 2 doesn't have a name, so it's "Yours faithfully." Both have commas after the sign-off. Both capitalize the first word of the body. Both follow the standard format.
Understanding how examiners grade these details helps you prioritize. Here's how greeting and closing mistakes map to band scores.
Band 7-8 (Coherence & Cohesion): Correct salutation with proper punctuation, matching closing, correct comma placement, appropriate register throughout the letter.
Band 6 (Coherence & Cohesion): Correct salutation, appropriate closing, maybe one small punctuation inconsistency or slight register slip.
Band 5 (Coherence & Cohesion): Incorrect salutation (too casual or wrong format), mismatched closing, multiple punctuation errors, register inconsistency.
The gap between Band 6 and Band 7 often comes down to perfection in these technical details. You can't afford to guess on this stuff.
Tip: One greeting or closing error might cost you 0.5 band points. Three errors across a letter might cost you a full band. These aren't massive deductions individually, but they add up fast, especially if you've got grammar or vocabulary issues elsewhere.
If you're working on IELTS Task 1 more broadly, remember that letter format is just one piece. You'll also want to check your tone consistency across the entire letter to make sure you don't slip into casual language mid-paragraph. Examiners notice tone shifts, and they deduct points accordingly.
Beyond format, make sure you're not overstating your claims or exaggerating. A lot of students start with perfect format, then write a complaint letter that sounds angrier than it should, or uses language that feels inflated. Format gets you started on the right foot, but tone keeps you there.
