Cover letters have a reputation problem: half of job seekers think no one reads them, and half of hiring managers say a good one still tips a decision. Both are right. A generic, templated letter is a waste of everyone’s time — but a specific, well-aimed one, in the situations that call for it, does real work. Here’s when to write one and how to make it count.
When a cover letter actually matters
Not every application needs one. It earns its place when:
- The posting asks for one — skipping it reads as not following instructions.
- You’re changing fields, where the letter explains a move a CV can’t (see how to change careers).
- There’s context to add — a relocation, a gap, an unusual path — that’s better framed than left to guesswork.
- It’s a speculative or referred application, where there’s no job description to answer and the letter is the pitch.
For a standard application to a role you’re an obvious fit for, a strong CV usually carries it. Don’t pad the process for its own sake.
The structure that works
A good cover letter is short — three or four tight paragraphs on one page — and follows a simple arc:
- Open with a specific hook, not a formula. Skip “I am writing to apply for…”; they know. Lead with why this role, at this company, and one concrete reason you’re a strong fit.
- Make the case in the body. Pick your two or three most relevant achievements and connect them explicitly to what the role needs. Don’t restate your CV — interpret it. Show you understand their problem and have solved a version of it before.
- Close with intent. A brief, confident sign-off: you’re keen to discuss how you can help, and you’re available to talk. No begging, no over-formality.
Tailor it, or don’t send it
The single thing that separates a read letter from a binned one is specificity. A letter that could be sent to any company will be treated as if it were. Every letter should name the company, reference the actual role, and use language from the job description. This is also where an applicant tracking system may scan for relevance — the same keyword logic as your CV (a CV format that passes ATS) applies.
If tailoring each one by hand is the reason you skip cover letters entirely, that’s exactly the task to automate rather than abandon.
Common mistakes that get letters binned
- Restating the CV line by line instead of adding new context.
- Talking only about yourself — what you want — rather than what you offer them.
- Generic flattery (“your prestigious company”) that signals no real research.
- Length. Over one page and it won’t be read to the end.
- Errors. A typo in the first line undoes the effort; proofread every time.
Career-change and speculative letters
Two situations lean hardest on the letter. In a career change, the letter connects your past to their future and turns an apparent mismatch into a deliberate move. In a speculative application — reaching out with no advertised role — the letter carries the whole pitch: who you are, the specific value you’d add, and why them. In both, research and specificity are everything. On how a letter complements the CV rather than repeating it, see the role of a cover letter with a CV.
The point
A cover letter is a targeted instrument, not a formality: use it when it adds something, keep it short and specific, and make it about their problem as much as your record.
