How to Write a Cover Letter (Without Sounding Like a Template)

The cursor blinks in an empty document, and you are staring at the phrase "Dear Hiring Manager." You have a job you want, a résumé that is more or less ready, and no idea what a whole page of cover letter is supposed to say that the résumé does not. So you reach for a template, fill the blanks, and it comes out sounding like every other letter in the pile.

The fix is not a better template. It is knowing what the letter is for.

The takeaways

• A cover letter answers one question: why you, for this specific posting. If a paragraph would fit any other job unchanged, it is doing no work.
• The shape is fixed, the content is not: a header, a one-line opening that names their problem, two or three proofs pulled from the posting, and a concrete close. Three or four short paragraphs, under one page.
• AI drafts, you decide: a generated letter that no human edited reads smooth and says nothing, and no tool can invent experience you do not have.

What is a cover letter actually for?

A cover letter exists to answer one question a résumé cannot: why you fit this exact posting, in your own words. The résumé lists what you did. The letter argues what it means for the role in front of you, using two or three details the employer themselves flagged as important. That framing is the whole job, and it is why cover letters someone actually reads start from the posting rather than from last month's letter.

So before you write a sentence, read the job posting twice and pull out the two or three things it clearly cares about: the responsibilities listed first, the ones repeated, the qualifications marked "required." Those are the questions your letter answers. Everything else is padding. A hiring manager reading fifty applications is scanning for one signal, that you understood the job, and a letter built from the posting's own priorities is the fastest way to show it.

How do you write a cover letter step by step?

Write it in four moves, top to bottom:

1. Header and greeting. Match your résumé header: name, phone, email, and a LinkedIn URL if you use it. Address a real person when the posting names one; a quick search on LinkedIn or the company site often finds the hiring manager. When it does not, address the team or the role and do not guess a name you are unsure of.
2. Opening line. One sentence that names their problem or the reason you fit, not your own life story. This is the sentence that earns the second sentence, so it is worth more time than the rest combined.
3. Two or three proof paragraphs. For each priority you pulled from the posting, give one concrete example: what you did and roughly what came of it. Connect it back to their need explicitly, so the reader does not have to.
4. A concrete close. Skip "I look forward to hearing from you." Offer a real next step, a short method you would bring, or a note that you have attached the work sample they asked for.

The order matters because a reader who stops after the opening line should still know why you are worth a second look.

How long should a cover letter be, and how many paragraphs?

Keep it to one page, three or four short paragraphs, roughly 250 to 400 words. The goal is not a word count; it is that every line earns its place. A letter that fills a page with restated résumé bullets is longer and weaker than a tight half-page that answers the posting directly. If you are cutting and cannot decide what goes, the length of a cover letter that gets read comes down to one test: could this sentence be pasted into an application for a different company? If yes, cut it.

The opening carries more than its share of that budget. A first line that repeats the job title tells the reader nothing they did not already know, while one that names their actual problem makes them read on. If the blank page is where you stall, the mechanics of starting a cover letter are worth their own read.

Should you use AI to write your cover letter?

Yes, as a first draft, but never send the raw output. A generated letter that no human edited tends to sound polished and say nothing, which is exactly the clean-but-forgettable letter that lands in the maybe pile and stays there. Treat what a model gives you as clay: cut the generic lines, sharpen the proofs, and put back the one specific detail only you know.

Here is the honest limit, stated plainly: any AI-drafted cover letter is a draft you review before sending, and it cannot invent experience you do not have. I built JobScalr around that constraint for my own job search in a tough market. It reads the specific posting and drafts a letter aimed at that role, grounded in a quick company-research step rather than a fill-in-the-blank template, and it will not invent a recipient's name the posting never gave. The tailoring is the slow part a tool can carry. The judgment about what is true, and what to keep, stays yours.

Common questions about writing a cover letter

Do I need a different cover letter for every job?

The structure carries over; the content should not. Reuse your header and maybe one framing line, but the opening, the proofs, and the company reference have to change with each posting. A letter that reads as reused loses the one advantage a cover letter has over a résumé.

What if I have no relevant experience?

Pull proof from adjacent places: a project, a course, volunteer work, a side task in an unrelated job. Name the transferable skill the posting asks for and show one time you used it. Honesty still wins; a cover letter reframes what is true, it does not manufacture a background you do not have.

Should I mention salary or a weakness in the cover letter?

Only if the posting asks. Do not volunteer a weakness or an employment gap unless it needs context the résumé already raises, and then keep it to one forward-looking sentence. Salary belongs in the letter only when the posting explicitly requests your expectation.

Does the cover letter matter if an ATS screens first?

Less, but it can still surface later. When an applicant tracking system (ATS) reads the application first, formatting and following instructions matter more than prose. A human usually reads the letter at the shortlist stage, so a copy-paste tell or a wrong company name in the file can still cost you at the worst moment.
