How to Write a Cover Letter That Gets Read

A cover letter is not a summary of your resume. The resume already lists what you did — the letter exists to answer two questions a list cannot: why this role, and why this company. Recruiters skim it in seconds, so the whole thing should fit in three short paragraphs on one page.

Paragraph 1 — the role, and why you fit

Name the exact job title and where you saw it, then one line on why you are a credible candidate. No throat-clearing, no "I am writing to express my keen interest". Get to the point in two sentences.

Paragraph 2 — your strongest relevant proof

Pick the single achievement that most closely matches what the posting asks for, and attach a number to it: a percentage, a dollar figure, a timeframe, a volume. One specific result beats three vague claims. This is the paragraph that decides whether the letter was worth opening.

Paragraph 3 — why this company, then close

This is where most letters fall apart. "I admire your commitment to innovation" could be sent to any company on earth, and recruiters read it as filler. Name something concrete instead — a product, a recent announcement, a way they work — and connect it to your own experience. Then close briefly and thank them.

The things that quietly cost you

• "To Whom It May Concern" — reads as a mass mailing. Find a name, or use "Dear Hiring Manager".
• Repeating your resume — they already have it. Add context it cannot carry.
• Talking only about what you want — the letter should be about what they get.
• Going over one page — length signals you could not identify what mattered.
• Leaving the previous company's name in — the single most common fatal typo in reused letters. Always reread before sending.

Should You Send One At All?

If the application asks for a cover letter, always include one — some systems and recruiters filter out incomplete applications before reading anything else. When it is genuinely optional, it is still worth writing for competitive roles, career changes, employment gaps, or anywhere you are applying slightly outside your obvious track record. Those are exactly the situations a resume alone handles badly.
