How to Write a Cover Letter That Actually Gets Read
A cover letter is not a second CV. It is not a 400-word version of your résumé in paragraph form. Yet that is exactly what most cover letters are — which is why most recruiters skim the first sentence and move on. The job of a cover letter is to do one thing your CV cannot: tell the reader, in plain language, why YOU specifically want THIS specific role at THIS specific company — and what you'll bring that other qualified candidates won't.
When a cover letter actually matters (and when it doesn't)
Before you spend an hour crafting the perfect letter, it helps to know whether it'll even be read. In some application contexts a cover letter is the deciding factor; in others it's quietly ignored. Knowing the difference saves you time and lets you put real effort into the ones that count.
Roughly speaking, cover letters matter most when a human is making a judgment call. They matter least when a recruiter is sifting through hundreds of applications looking for keyword matches. Plot your application on that axis and the answer is obvious.
- Smaller companies (under ~200 employees) where the hiring manager personally reads the applications
- Mission-driven organisations (non-profits, education, healthcare) where culture fit is part of the screen
- Career-change applications where your CV alone doesn't tell the story of why you're pivoting
- Applications where you have a referral and the letter is a courtesy explanation of the introduction
- Jobs with an obvious employment gap or unusual trajectory — the letter is where you address it briefly and confidently
Conversely, for high-volume tech recruiting at large companies, automated portals that ask for a cover letter but immediately route it to a folder no one opens, and any application where the form explicitly says "optional" — a great CV does more for you than a generic cover letter ever will. Skip it or paste a two-sentence version.
How applicant tracking systems handle (and often ignore) cover lettersThe structure that works
A good cover letter is short — three or four short paragraphs, under 350 words total. Long letters signal you don't know what's important. Short letters force every sentence to carry weight. The structure below is the one that consistently outperforms the alternatives across industries and seniority levels.
1. The opening line — never the cliché one
Every recruiter has read "I am writing to apply for the position of…" ten thousand times. The sentence wastes the most valuable real estate in your letter. Open instead with a single sentence that proves you've done your homework — a specific detail about the company, a recent product launch, a problem the team is publicly working on.
Example, weak: "I am writing to apply for the Senior Backend Engineer position at your company."
Example, strong: "Your engineering blog post last month about scaling the messaging service from 100k to 1M concurrent connections lined up exactly with the kind of problem I spent two years solving at Acme Corp."
- Reference something specific: a launch, a blog post, a podcast appearance, a recent funding round
- Show the connection to your own work in the same sentence
- Avoid "passion" and "excited" — every other applicant uses them
- If you genuinely don't have a hook, write "I'm applying for [role] — here's what makes me a strong fit" and skip to the substance. Honest beats fake-enthusiastic
2. The "why this company" paragraph
One or two sentences that show you understand what the company is trying to do and why it's interesting to you. Not the bland mission-statement paraphrase from the careers page — something specific about the product, the market position, or a recent strategic move. Two sentences. No more.
3. The "why you fit" paragraph (the heart of the letter)
This is where you tell ONE story. Not a list of skills, not a recap of your CV — one concrete moment from your career that demonstrates the single most important skill the job needs. Three sentences: situation, action, result. This is what readers remember a week later.
Pick the moment that maps most directly to what the job description emphasises. Don't try to cover everything — your CV already does that. The letter's job is to make ONE thing memorable.
4. The closing CTA — never "look forward to hearing"
Replace the cliché closing with an invitation to a specific next step. "Happy to walk through the onboarding redesign I mentioned in more detail — it's the part of the work I'm most proud of and the parallels with your Q3 plan are worth a 20-minute conversation." You're inviting action, not waiting passively.
Tone, length, and formatting
The substance carries the letter, but the surface still matters — these are the details that signal professionalism without distracting from the content:
- Length: three or four paragraphs, under 350 words. One page maximum, ever
- Tone: conversational but professional. Write like a smart colleague is reading, because one is
- First person, active voice. "I led the rewrite" not "The rewrite was led by me"
- Same font, same header, same letterhead as your CV. Matching the visual identity is a small touch that signals attention to detail
- Single-spaced body, plain text, no tables, no graphics, no fancy colour accents
- Address it to a real person when you can. "Dear Hiring Manager" is acceptable; "Dear Sir or Madam" reads as outdated
- Save as PDF, named FirstName-LastName-CoverLetter-CompanyName.pdf
Tailoring without rewriting from scratch
The single best move you can make for any application is to tailor the letter to that one specific role. A generic letter you send to twenty companies has roughly the same conversion rate as no letter at all — the math is brutal but consistent. A focused letter you send to five companies will outperform it dramatically.
Tailoring doesn't mean rewriting from scratch. It means swapping out one or two key sentences per letter. Build a template with placeholders for company, role, opening hook, and the chosen story. Five minutes per application instead of forty-five — and the result is a letter that feels written specifically for that role because, in the parts that matter, it was.
- Save a master letter with [COMPANY], [ROLE], [HOOK], and [STORY] placeholders
- For each application, fill in those four blanks — done in five minutes
- Mirror the language of the job description in your "why you fit" paragraph
- Update your CV's top third for the same role at the same time — the letter and CV should reinforce each other
Mistakes that get cover letters trashed
A few patterns reliably sink an otherwise good letter before the reader gets past the first paragraph. Avoid all of these:
- Restating your CV in paragraph form — the reader already has the CV; the letter must add something new
- Starting with "I am writing to apply for…" or any variant — wasted first impression
- Generic praise of the company that could apply to any competitor ("a leader in the industry")
- Listing every skill instead of telling one specific story
- Asking for the job ("Please consider me for this role") — the application IS the ask; don't waste a sentence
- Typos, especially in the company name or the hiring manager's name — instant trash bin
- Mismatched tone: overly casual ("Hey there!") for corporate roles, overly stiff for startups
- Length over one page — almost always means you didn't edit hard enough
A 5-minute pre-send checklist
Before clicking submit, run through this list. It catches roughly 90% of the issues that cause an otherwise strong application to land flat:
- Opening sentence references something specific about the company — not generic
- Company name and hiring manager's name are spelled correctly (check the website twice)
- The middle paragraph tells ONE concrete story with a measurable result
- Closing invites a specific next step, not "I look forward to hearing from you"
- Total length: three to four paragraphs, under 350 words, one page
- Same font and header as your CV; saved as PDF
- File named FirstName-LastName-CoverLetter-CompanyName.pdf
- Read aloud once — the ear catches awkward phrasing the eye misses
A cover letter that does all of this won't guarantee an interview — but it gives you the best shot the format can offer. Most applicants send a generic template they barely read themselves. A genuinely tailored, story-driven letter stands out without any clever tricks; it just sounds like a real person who actually wants this specific job, talking to the person who will read it.
