The 150-Word Cover Letter: A Formula for When Yours Actually Gets Read
Most cover letters are skimmed for four seconds or never opened at all. That's an argument for making yours shorter and sharper — not for skipping it.
The honest position on cover letters in 2026: a large share are never opened, most of the rest are skimmed in seconds, and a small but decisive minority are read closely by exactly the person who decides whether you get an interview. You can't tell in advance which kind of employer you've got.
That uncertainty is the whole design brief. It argues for a letter that costs you five minutes, survives a four-second skim, and rewards a proper read. Which means short, specific, and structured — not a page of prose about how passionate you are about their mission.
When a cover letter actually moves the needle
Not always. Knowing when it matters lets you spend your effort where it converts.
| Situation | Does it matter? | Why |
|---|---|---|
| Small company, hiring manager reads directly | A lot | One person is deciding, and they read everything |
| Your CV needs an explanation (gap, career change, relocation) | A lot | It's the only place to answer the obvious question in your own words |
| The posting explicitly asks for one | A lot | Not sending one is a filter you fail before anyone reads you |
| Speculative / unadvertised application | A lot | There's no posting to match against — the letter *is* the application |
| Large corporate, high-volume ATS role | Some | May not be read, but rarely hurts; keep it very short |
| Recruiter-led process, agency submission | Little | The recruiter usually writes their own summary for the client |
| Marked "optional" | Some | Sending a good short one is a cheap differentiator |
The asymmetry that settles the argument
A short, specific letter takes five minutes and can only help. A missing letter can silently disqualify you where one was expected. Given that you can't see which employer you've got, the expected value of sending a good short one is always positive.
The 150-word structure
Four paragraphs. None of them longer than three sentences. Every one of them doing a specific job that the others can't.
The hook (1 sentence)
Name the role and the single strongest reason you're a fit. No "I am writing to apply for the position of…" — they know why you're writing, and you've spent your best line on paperwork.
The proof (2–3 sentences)
One achievement that maps directly onto the job's main responsibility, with a number. Not a summary of your CV — one thing, in detail, chosen because it matches their first bullet.
The connection (2 sentences)
Something specific about *this* employer that you couldn't say about a competitor, tied to what you'd bring. This is where generic letters die and specific ones win.
The close (1 sentence)
Direct, confident, no apology. "Happy to walk through how I'd approach the first 90 days." Then your name.
The 400-word version nobody finishes
- •"I am writing to express my strong interest in…"
- •A paragraph restating your CV chronologically
- •"I am a hard-working team player with excellent communication skills"
- •"I would welcome the opportunity to discuss…"
- •Two more paragraphs about their company mission
The 150-word version that lands
- •A first line naming the role and your strongest match
- •One achievement with a number, chosen to mirror their top requirement
- •One sentence proving you know something real about them
- •A direct close offering a next step
A worked example
Applying for a Customer Success Manager role at a B2B software company that mentions churn reduction and onboarding in its first two bullets:
I'm applying for the Customer Success Manager role — onboarding and churn are the two things I've spent the last four years on. At Northwind I owned a 120-account SME book and rebuilt the 30-day onboarding sequence around a single success milestone rather than a feature tour. Annual churn on that book fell from 14% to 8% over two renewal cycles, and time-to-first-value dropped by nine days. Your changelog suggests you've just moved upmarket into mid-size accounts, which usually breaks an onboarding flow designed for self-serve. That's the transition I've run once already. Happy to walk through how I'd approach the first 90 days.
What makes it work
Every sentence contains something the reader couldn't have predicted. The numbers are specific, the observation about their business is one they'd recognise as accurate, and the close offers value rather than asking for a favour.
The slow part is the matching, not the typing. Our cover letter generator asks a few personalisation questions, reads the job description and drafts from your CV — so you edit rather than start from a blank page. Build the CV first and the letter comes with it.
Start with my CVThe five lines to delete on sight
- "I am writing to apply for the position of…" — the reader knows. Spend the line on something they don't.
- "I believe I would be a great fit for your company." — a claim with no evidence attached is noise.
- "As you can see from my attached CV…" — never make the letter a footnote to the CV.
- "I am a hard-working, motivated team player." — adjectives anyone could write about anyone.
- "Thank you for taking the time to consider my application." — pre-emptive gratitude reads as low status. Close with a next step instead.
The one unforgivable error
The wrong company name. It happens constantly with copy-pasted letters and it ends the application instantly — because it proves the letter isn't about them. If you reuse a template, the company name and the specific observation are the two things to check twice.
The research that makes it specific (five minutes)
The "connection" paragraph is what separates a letter that works from a letter that's merely inoffensive, and it needs one genuine fact. Five minutes gets you one.
- 1Read the posting's first three bullets. These are the job. Everything below is usually boilerplate.
- 2Check the company's news or changelog. A funding round, a launch, a new market, a regulatory change — that's what's driving the hire.
- 3Look at who's already in the team on LinkedIn. Their backgrounds tell you what the company values in the role.
- 4Find the one thing you can say about them and no one else. That's your third paragraph.
Format notes people get wrong
Send it as a PDF unless a form asks for plain text, name the file `Firstname-Lastname-Cover-Letter.pdf`, and if there's a single text box on an application form, paste the same four paragraphs there — no letterhead, no address block. Address a named person if you can find one, "Hiring Team" if you can't. Never "To Whom It May Concern".
The short version
- You can't know which employers read letters, so make yours cheap to write and impossible to skim past.
- Four paragraphs, ~150 words: hook, proof with a number, a specific observation about them, a direct close.
- One achievement in detail beats a summary of your CV.
- Delete every sentence that could appear in anyone else's letter.
- Five minutes of research buys you the one specific line that makes it work.

Frequently asked questions
Are cover letters still necessary in 2026?
They're not universally read, but they're still expected often enough that skipping one carries real risk — and where a hiring manager reads directly, they matter a lot. Because a good short letter takes five minutes and can only help, the sensible policy is to always send one and keep it to about 150 words.
How long should a cover letter be?
Around 150–200 words, four short paragraphs, comfortably under one page. Longer letters aren't read more carefully — they're read less carefully, or abandoned. The constraint is also useful: it forces you to pick your single strongest piece of evidence instead of listing everything.
Should I write a new cover letter for every application?
Keep the structure and rewrite two things: the achievement you lead with (chosen to mirror the posting's top requirement) and the specific observation about the employer. That's five minutes per application, not thirty, and it's the difference between a letter that reads as addressed to them and one that reads as broadcast.
Who should I address the cover letter to?
A named person if you can find one on the posting, the company site or LinkedIn — it demonstrably signals effort. If you genuinely can't, "Dear Hiring Team" is perfectly acceptable and modern. Avoid "To Whom It May Concern" and "Dear Sir/Madam", both of which read as dated and unresearched.
What if the application form has no place to upload one?
Look for a free-text field — "anything else you'd like us to know", or a message box — and paste the four paragraphs there without the letterhead. If there's genuinely nowhere, don't force it: use the space you do have (the summary on your CV) to carry the same message.
