What separates a cover letter that gets read from one that gets skipped
Two candidates apply for the same marketing coordinator role. Candidate A opens with: "I am writing to express my interest in the Marketing Coordinator position I saw advertised on your website." Candidate B opens with: "Your job posting mentions you're scaling from 2,000 to 10,000 email subscribers this year. I grew a 1,800-person list to 9,400 in fourteen months at my last role, and I'd like to do it again for you." Same qualifications on paper. One letter gets skimmed and discarded; the other gets the resume pulled to the top of the pile.
The difference is not writing talent. It's that Candidate B treated the cover letter as a targeted argument, not a formality. A cover letter is the one document where you get to connect the dots a recruiter would otherwise have to connect themselves: why this specific role, why you specifically, and what evidence backs it up.
The structure that consistently works is four short blocks.
- The hook (1-2 sentences): Name the company and a specific detail from the posting or the business. Show you did more than paste your resume into a portal.
- The proof (2-3 sentences): One or two concrete, quantified wins that map directly to the job's stated needs. "Reduced onboarding time from 6 weeks to 9 days" beats "strong process-improvement skills."
- The fit (2-3 sentences): Why this company and this mission, in language that's clearly about them, not generic flattery. "I admire your company culture" is filler. "Your engineering blog's stance on shipping small and often matches how I've worked best" is specific.
- The close (1-2 sentences): A confident, low-pressure call to talk. "I'd welcome the chance to walk you through how I'd approach your first 90 days."
Keep the whole thing to 250-350 words and three or four short paragraphs. Hiring managers read dozens of these. A wall of text signals you didn't edit; a tight, specific letter signals you respect their time and know what you're doing. Address a real person by name whenever you can find one. "Dear Hiring Manager" is acceptable; "To Whom It May Concern" reads as if you couldn't be bothered.
The most common reason good candidates write bad cover letters is that they make the letter about themselves instead of the employer. Re-read Candidate A's opening above: every word is about what the applicant wants. Candidate B's opening leads with the company's problem and only then offers proof of a solution. That shift, from "here's what I'm looking for" to "here's what you need and how I deliver it," is the entire difference between a letter that feels like a favor request and one that feels like a value proposition. Before you send anything, run a simple test: count how many sentences start with "I" versus how many engage with the company's actual needs. If "I" dominates, you've written a letter about yourself, and the reader can feel it. Rebalancing toward the employer is usually a five-minute edit that changes how the whole letter lands.
