Here's the thing: most students who don't hit Band 7+ on IELTS letters have no idea that their opening line is doing way more damage than they realize. Your first sentence isn't just saying hello. It sets your tone, shows the examiner how well you control grammar, and proves whether you understand the difference between formal and informal register. Mess it up, and you've already lost points in Task Response and Coherence & Cohesion before you've even gotten to your main argument.
I'll walk you through the exact mistakes I see in student submissions, show you how to spot them in your own writing, and give you the fixes that will actually push your band score up.
You've got 20 minutes for Task 1. That's roughly 150 words to make your case. Every sentence counts. The opening is your first impression, and IELTS examiners form opinions fast.
According to the official IELTS band descriptors for General Training Writing, Task Response checks whether you've actually answered the question and covered all the main points. That starts in the opening. If your salutation and first sentence are confused or too casual, the examiner immediately questions whether you understand register at all.
Here's the math: a weak opening costs you marks across multiple criteria—Task Response, Coherence & Cohesion, Grammatical Range & Accuracy, and Lexical Resource. A strong opening gives you momentum and buys you goodwill. When you use an IELTS writing checker, one of the first things it flags is whether your letter opening matches your task.
This is where most students mess up. They start with a formal salutation but then slip into casual language, or they go the opposite direction. Mixing formal and informal register is one of the fastest ways to drop your band score.
Weak: "Dear Sir or Madam, I'm writing because I wanna complain about my apartment building. Like, the noise at night is crazy and the landlord won't fix it."
Good: "Dear Sir or Madam, I am writing to lodge a formal complaint regarding persistent noise disturbances in my apartment building. The landlord has failed to address these issues despite my previous requests."
See it? The weak version starts formal and then crashes into "wanna" and "crazy." That's inconsistent register, and the examiner marks it down on your Lexical Resource and Grammatical Range & Accuracy scores.
Your opening sentence needs to match your salutation. Formal salutation (Dear Sir/Madam, Dear Mr. Jones) means formal register all the way through. Casual salutation (Hi Sarah, Hello James) lets you be conversational, but you still need clear structure.
Let me be direct: "I am writing to you" followed by rambling isn't a strong opening. Your purpose needs to be specific and immediately clear.
Weak: "Dear Manager, I am writing regarding several matters concerning my stay at your hotel. There were a few things that happened during my visit."
Good: "Dear Manager, I am writing to bring to your attention three significant issues I encountered during my recent stay: inadequate heating in my room, missing amenities, and poor service from reception staff."
The strong version tells you exactly what the letter's about in one sentence and previews what's coming. That's Task Response working. The examiner ticks the box: "Yes, they've addressed the task clearly." The weak version hides behind "several matters" and "a few things." It reads like you haven't organized your thoughts.
Use this pattern: "I am writing to [specific verb: complain about, request, explain, apologize for] [specific issue]." Specificity gets you marks. When you run your letter through an IELTS writing correction tool, this is one of the first things it checks.
Some letters need context. If you're writing to a university about a late application, saying "I am writing regarding my application" leaves the reader hanging. Why now? What's the reason?
Weak: "Dear Admissions Officer, I am writing to discuss my application for the Master's program."
Good: "Dear Admissions Officer, I am writing to request a reconsideration of my application for the Master's programme in Environmental Science, which I submitted on August 15th. I would like to provide additional information regarding my academic credentials."
The strong version includes the programme name, the submission date, and your reason for writing. That's coherence and planning, not just "I'm contacting you about something."
Tip: If the task prompt mentions specific details (dates, reference numbers, event names), repeat them in your opening. This proves you've read the task carefully and actually understood it.
Small errors here add up. A misplaced comma, missing line break, or wrong punctuation after the salutation marks you as careless. Proper letter formatting is part of Coherence & Cohesion, even if it seems like a minor detail.
IELTS examiners expect proper letter formatting. A missing comma after the salutation or wonky spacing costs you under Coherence & Cohesion. Presentation and organization matter, and they start with your opening line.
Tip: Salutation + comma, then press Enter. If it looks like a real letter, it probably is one.
Some letters call for an apology. Others don't. But even when they do, leading with self-doubt kills your voice.
Weak: "Dear HR Manager, I am sorry to bother you, but I was hoping I might possibly inquire about my job application status, if that's okay."
Good: "Dear HR Manager, I am writing to inquire about the status of my application for the Senior Analyst position, reference number JA-2026-447, submitted on July 20th."
The weak version uses hedging language ("I am sorry to bother you," "I was hoping I might possibly") that sounds like you don't deserve an answer. The examiner sees lack of confidence and clarity, which hurts your Lexical Resource score.
The strong version is direct, professional, and includes a reference number. You're stating your request as legitimate. There's a real difference between being polite and being apologetic. Formal letters need politeness, not excessive apologies.
IELTS Task 1 formal letters do not use contractions. But many students slip them in without thinking, and it's an easy way to lose marks.
Weak: "Dear Manager, I'm writing to let you know I've been having issues with my booking, and I'd like to fix it."
Good: "Dear Manager, I am writing to report issues with my recent hotel booking and to request immediate correction."
The weak version uses I'm, I've, and I'd. These are grammatically correct in casual writing but totally inappropriate in formal IELTS letters. The examiner marks this as a register break, costing you marks in Grammatical Range & Accuracy and Task Response.
The rule: no contractions in formal letters. Not "do not," "will not," "cannot"—write them out fully. An IELTS essay checker will catch these instantly because they're such a clear signal of informal writing.
Tip: Before you finish, search your letter for apostrophes ('). Replace every one with full words. This single habit kills a major formal letter mistake.
You don't need a tool. Use this checklist on your opening before you move to the body:
If you answer "yes" to questions 1-4 and "no" to questions 5-6, you're good. If you hesitate on any question, rewrite that sentence. This takes 90 seconds. It's worth it.
For deeper analysis, an IELTS writing evaluator can break down exactly where your opening loses marks, but this manual checklist works just fine to catch the most common errors.
