How to Write a Cover Letter That Recruiters Actually Read
Quick answer: a strong cover letter is under 300 words, opens with the specific role and why you fit it, proves one relevant achievement with a number, addresses the employer's likeliest doubt, and closes with a clear next step. Anything beyond that is decoration.
Do cover letters still matter?
They matter when they are read, and they are read most often for competitive roles, career changes and applications with an obvious gap to explain. A tailored letter is also the cheapest way to answer the question a resume cannot: why this company, and why now.
The four-paragraph structure
Use the same skeleton every time and change only the evidence.
- Paragraph 1 — the role, where you saw it, and a one-line claim of fit
- Paragraph 2 — one achievement with a metric that maps to their top requirement
- Paragraph 3 — the doubt they will have (gap, pivot, location) answered directly
- Paragraph 4 — what you want next, and a polite, specific close
Tailoring at scale
Write a master letter with three interchangeable achievement blocks. For each application, swap in the block closest to the posting's first requirement and rewrite the opening line with the company's own language. Two minutes per letter, no templated feel.
Common mistakes
Most rejected letters share the same handful of problems.
- Restating the resume instead of interpreting it
- Opening with 'I am writing to apply for…' and no point of view
- Praising the company for two paragraphs without evidence about you
- Exceeding one page, or using a formal register the company never uses
- Leaving another company's name in from a previous application
Frequently asked questions
How long should a cover letter be?
200–300 words, or roughly half a page. Recruiters skim, so the value has to be in the first three lines.
Should I submit a cover letter when it is optional?
Yes for competitive, senior or career-change applications. For high-volume entry roles, prioritise resume quality first.
Can AI write my cover letter?
AI should draft the structure and first version from your real achievements; you edit facts and tone. Never let it invent results.
