1. When You Actually Need a Cover Letter
Not every application needs one. Sending a weak cover letter is worse than sending none, so it helps to know when it counts.
Always send one when — The listing asks for it, you are changing industry or role, you have an employment gap to explain, or you are applying to a small company where a human reads every application.
It is worth sending when — You are genuinely excited about this specific company, or you were referred by someone who works there — name them in the first line.
You can skip it when — The application form has no field for it, or the listing explicitly says not to send one. Never paste one into a field meant for something else.
2. The Structure
Five parts, one page, three to four short paragraphs. Anything longer will not be read in full.
Header
Your name, email, phone and city — matching your resume exactly. Add the date and the company name below it.
Greeting
Use the hiring manager's name if you can find it on LinkedIn or the listing. If you truly cannot, 'Dear Hiring Manager' is fine. Never 'To Whom It May Concern'.
Opening paragraph
Say which role you are applying for and give them one concrete reason to keep reading. Two or three sentences.
Body paragraphs
One or two paragraphs proving you can do the job, using specific examples with numbers. This is the part that decides the outcome.
Closing
Restate your interest, say what you would like to happen next, and thank them. Two or three sentences.
3. How to Open
The first sentence decides whether the rest gets read. Lead with something specific — a result, a referral, or a genuine reason you want this company.
Openings that work
- ✓"I increased organic traffic 140% in eighteen months at a company your size — I would like to do the same for [Company]."
- ✓"[Name] on your design team suggested I apply for the Product Designer role, and after reading your case study on [project], I understand why."
- ✓"I have spent four years building payment systems for high-volume retail, which is exactly the problem your job posting describes."
Openings that get skimmed past
"I am writing to apply for the position advertised on your website." — They know. It tells them nothing, and it is how most applications start.
4. The Body — Proving You Can Do It
This is where applications are won and lost. Do not restate your resume in sentences — pick two or three requirements from the listing and prove each one.
Pick from their list, not yours — Re-read the job description and choose the two or three requirements repeated most. Those are what they care about. Answer those.
One example per requirement — A specific situation with a specific outcome beats three vague claims about being a hard worker.
Use numbers — Percentages, revenue, users, team size, time saved. 'Reduced processing time by 60%' lands. 'Improved efficiency' does not.
Show you researched them — One sentence referencing their product, a recent launch or their market shows you did not send the same letter to forty companies.
Mirror their language — If they say 'customer success' do not write 'client servicing'. This matters for both the human reader and any keyword scan.
Before and after
I have excellent communication skills and work well with cross-functional teams.
I ran the weekly release sync between engineering, design and support for two years — the handover doc I introduced cut post-release support tickets by about a third.
The first is a claim anyone can make. The second is a specific thing you did, with a result attached.
I am passionate about your mission and would love the opportunity to grow with your company.
I have used your API in two side projects, and the versioning approach you took is the reason I trust it over the alternatives. I would like to work on the team that makes those calls.
The first is about what you want. The second proves you have actually engaged with their product.
I am responsible for managing the company's social media accounts.
I grew our LinkedIn following from 2,000 to 14,000 in a year by shifting from product posts to customer stories — that channel now drives about 20% of inbound demos.
'Responsible for' describes a job description. The rewrite describes an outcome you own.
5. Special Situations
Most guides assume a straightforward application. These are the cases that actually make people freeze.
No job posting — cold outreach
Lead with a specific observation about their business and what you would work on, not with your availability. Keep it to three short paragraphs and end by asking whether it is worth a conversation, not for a job.
You were referred by someone
Name them in the first sentence — it is the single strongest opening you can have. 'Priya on your data team suggested I get in touch about the analyst role.' Then move straight to why you fit.
You are changing industry
Address it directly in the second paragraph rather than hoping it goes unnoticed. Name the transferable skill, give the evidence, and say why you are moving. Unexplained career changes make readers uneasy; explained ones read as deliberate.
You have an employment gap
One sentence, plainly stated, then move on. Study, caring responsibilities, health, redundancy or freelance work are all normal. The tone matters far more than the reason.
You do not meet every requirement
Almost nobody does. Lead with the requirements you exceed, address the biggest gap once with how you are closing it, and do not apologise for the rest.
Applying by email rather than a form
Put the letter in the email body, not only as an attachment — many people never open the file. Attach the resume as PDF. Keep the subject line factual: 'Application — Marketing Manager — Priya Mehta'.
6. How to Close
Short and direct. Do not apologise, do not beg, and do not over-explain.
- ✓Restate your interest in one sentence — briefly, without repeating the opening.
- ✓Say what you would like next: 'I would welcome the chance to discuss how I could help.'
- ✓Thank them for their time. One sentence.
- ✓Sign off with 'Best regards' or 'Sincerely' and your full name.
- ✓Never end with 'I look forward to hearing from you at your earliest convenience.' It reads as filler.
7. Full Example
Marketing Manager — 240 words
Dear Ms. Sharma, I increased organic traffic 140% in eighteen months at a D2C brand roughly your size, and your posting for a Marketing Manager describes exactly that challenge. I would like to bring the same approach to [Company]. Your listing puts content-led growth and paid efficiency first. At [Current Company] I rebuilt our content strategy around search intent rather than volume, taking us from 12,000 to 29,000 monthly organic sessions and cutting our blended CAC by 34%. I did that with a team of three and no increase in budget. The second priority you mention is cross-functional work. I run our weekly growth review with product and sales, which is how we caught that 60% of trial signups were never activating — a fix that added ₹40 lakh in annual recurring revenue once product shipped the change. I have followed [Company] since your [specific product] launch, and the way you position against larger competitors is the kind of problem I want to work on. I would welcome the chance to discuss how I could help. Thank you for your time. Best regards, Priya Mehta
8. Common Mistakes
Restating your resume — If they can read it on your resume, it does not belong here. The cover letter adds context the resume cannot.
Making it about you, not them — 'This role would be a great opportunity for my growth' is about you. Rewrite it as what you bring.
Sending the same letter everywhere — The company name in one line is not tailoring. If your letter would work for any employer, it works for none.
Going over one page — 250 to 400 words. Nobody reads a two-page cover letter.
Typos and the wrong company name — The single most common reason a good letter gets binned. Read it aloud once before sending.
Attaching it as the wrong file type — Send PDF unless they ask otherwise. It preserves your formatting on every device.

Open Cover Letter Generator9. Frequently Asked Questions
- How long should a cover letter be?
- 250 to 400 words, three to four short paragraphs, one page maximum. If it runs longer, you are almost certainly restating your resume.
- Do I need a cover letter if the application says it is optional?
- Send one. 'Optional' means most candidates will skip it, which makes it a cheap way to stand out — as long as it is tailored and short.
- What if I cannot find the hiring manager's name?
- 'Dear Hiring Manager' is perfectly acceptable. Spend two minutes on LinkedIn first, but do not guess a name and get it wrong.
- How do I write one with no work experience?
- Lead with coursework, projects, internships or volunteer work, and treat them like jobs — what was the situation, what did you do, what was the result. Enthusiasm plus one concrete example beats a list of adjectives.
- Should the design match my resume?
- Yes. Same font, same header, same colour. It reads as one considered application rather than two separate documents.
- Can I use AI to write my cover letter?
- Use it for the first draft, then edit it. AI is good at structure and getting you past the blank page; it does not know your specific numbers or why you actually want this job. Those parts have to come from you.
