How to Write a Cover Letter That Gets Read

Nobody enjoys writing cover letters, and a fair number of people have concluded they no longer matter. That's half right. Most are skimmed or skipped, and a generic one changes nothing. But the ones that get read tend to get read at the moment a decision is genuinely close — which makes the effort worth understanding rather than abandoning.

This guide covers when a cover letter actually influences an outcome, a structure that works, and how to handle the situations that are the whole reason the document exists.

When It Actually Matters

Being honest about this saves a lot of wasted effort.

It matters most when:

• The posting asks for one. Not submitting is read as not following instructions, and in some processes the application is incomplete without it.
• Your resume raises an obvious question. A career change, an employment gap, a relocation, a step down in seniority, a short tenure. The letter is where these get explained in one confident sentence, which is far better than leaving a reader to speculate.
• The role is senior or specialised. Fewer applicants, more careful reading, and judgement matters more than keyword coverage.
• The organisation is small. A founder or hiring manager reading twenty applications reads differently from a recruiter processing four hundred.
• The field values writing. Communications, policy, law, journalism, marketing, education. Here the letter is a work sample whether or not anyone calls it that.

It matters least when: the application is high-volume and automated, the posting explicitly says not to include one, or the field screens almost entirely on technical credentials. Even then, a short one costs ten minutes and occasionally lands.

The resume says what you have done. The cover letter says why you are applying to this job in particular. If your letter does not answer that second question, it is doing the resume's work again and adding nothing.

A Structure That Works

Four paragraphs, 250 to 400 words total. Longer than that and it stops being read.

Paragraph one — the specific opening. Name the role, and lead with the single most relevant thing about you. Not "I am writing to apply for," which wastes the only line guaranteed to be read. Two or three sentences.

Paragraph two — the strongest evidence. One concrete example that maps directly onto what the posting emphasises. Not a list — one story, with a number in it. This is where you demonstrate rather than assert, the same principle covered in our guide on making a resume memorable.

Paragraph three — why this organisation. Something specific and verifiable: a product decision, a recent change, a stated approach, the shape of the team. This is the paragraph that separates a tailored letter from a template, and it is also the easiest to fake badly. If you cannot find anything genuine to say, a shorter letter without this paragraph is better than a hollow one.

Paragraph four — context and close. Anything the resume cannot carry: the reason for a transition, a gap, a relocation, availability. Then a plain closing sentence. No elaborate sign-off.

If you have nothing to put in paragraph four, drop it. A tight three-paragraph letter beats a padded four.

Openings That Are Not Wasted

The first sentence decides whether the rest is read. Four that work, against the default that doesn't.

A referral opening outperforms everything else where it is available, so use it whenever it is honest.

The Situations the Letter Exists For

These are the cases where a cover letter genuinely changes an outcome, because the resume cannot address them without becoming something it is not.

• A career change. One or two sentences connecting where you have been to where you are going. The resume should demonstrate the connection through translated experience — the technique is in writing a resume for a career change — while the letter states the intent plainly.
• An employment gap. Two sentences maximum, factual, no apology, then move on. The resume should already carry a short label; the wording for each situation is in explaining employment gaps.
• Relocating. Say so directly, including whether you are already committed to the move and whether you need relocation support. Ambiguity here gets applications set aside.
• Applying below your level. Address it, because an over-qualified application otherwise reads as a flight risk. Give the real reason — better fit, reduced scope by choice, a sector you want to be in.
• Missing a stated requirement. One sentence on what you have instead, then move on. Do not enumerate everything you lack.
• A short tenure or dismissal. Brief and neutral. "The role was eliminated in a restructure four months in" closes the question without inviting more.

What Sinks a Cover Letter

1. Summarising the resume. The reader has it. Repeating it in prose wastes the one document where you can say something else.
2. Generic enthusiasm. "I have long admired your commitment to innovation" is written by everyone about everyone and signals that you did no research.
3. Making it about what you want. "This role would be an excellent opportunity for my growth" centres your needs. The employer is solving their problem, not yours.
4. Length. Past 400 words attention drops sharply. A single page with white space, always.
5. Not changing the company name. Obvious, common, and immediately fatal. Check it twice.
6. Over-explaining a weakness. One sentence closes a question; a paragraph opens three more.
7. "To Whom It May Concern." Find a name where you reasonably can. "Dear Hiring Team" is a fine fallback; the archaic form is not.
8. Uniform AI phrasing. Models produce fluent, generic letters very easily, and readers have started noticing the pattern. The same caveats as elsewhere apply — see using AI without losing the truth.

One practical note on format: send it as a PDF with the same header, font, and name styling as your resume, so the two read as one application. Where the application form has a text box instead, paste plain text and check the line breaks survived.

The letter only helps if the resume behind it holds up, which is the larger part of the work — the diagnostic is in fixing a resume that isn't getting callbacks, and the per-application adjustments are in tailoring to a job description.
