Does the cover letter still matter?

Yes — more than many job seekers assume. In Jobscan’s 2025 recruiter survey (n=384), 54% of recruiters said a personalized cover letter influences their decision. The word “personalized” is doing the work: a generic letter adds nothing, but a letter that shows you researched the company and can articulate why you fit reliably moves the needle.

There is also a selfish benefit for you: writing a targeted letter forces you to clarify your own story — what you did, what you’re good at, what you want next. That clarity shows up in interviews too.

The four-paragraph structure

Recruiters scan, they don’t read. Keep the letter to four short paragraphs:

  1. The hook. Which role, which company, and one line on why this specific opportunity.
  2. The fit. 2–3 evidence-based strengths that match the job description.
  3. The proof. One concrete achievement — ideally with a number — that demonstrates those strengths.
  4. The close. A clear next step (“I would welcome a conversation”) plus thanks.

The Cover Letter Builder generates exactly this structure in three tones; fill in the fields and it does the sentence assembly for you.

Openings that earn a second sentence

The first line decides whether the rest gets read. Avoid the classics that every candidate writes: “I am writing to apply for…” and “I am a hard-working individual with…”. Instead, open with specificity. Three patterns that work:

  • The mission hook: “Your team’s work on financial literacy for small businesses is exactly the problem I want to spend my next five years on.”
  • The evidence hook: “I led a redesign that lifted activation 23% — and reading your description of the onboarding challenge, that feels directly relevant.”
  • The reference hook: “Dana Kim, your head of design, suggested I reach out about the Senior Product Designer role.”

Proof, not adjectives

Every sentence should be replaceable with “so what?” — and survive it. “I am passionate about data” fails. “I built a churn model that saved $1.2M per year” survives. When you are tempted to write a quality (“detail-oriented”, “results-driven”), convert it into evidence: the project, the action, the outcome. If you lack a number, describe the process and the scale (“a team of six”, “across 14 regions”).

Length, tone and format

Three to four paragraphs, under 250 words, one page max. Match tone to culture: formal for finance and law, warm for startups and education, direct when the posting is high-volume. Address a named person whenever you can find one — “Dear Ms. Harper” is dramatically stronger than “To whom it may concern”. If you cannot find a name, use “Dear Hiring Team”.

Five mistakes that get letters deleted

  • Generic template leftovers. If the company name can be swapped and nothing changes, it reads as mass mailing.
  • Repeating the resume. The letter should add narrative, not duplicate bullet points.
  • Too long. A full page of prose gets skimmed once and archived.
  • Spelling the company’s name wrong. Terminal.
  • No proof. All claims, no evidence — recruiters have seen a thousand of these.

One more rule: never state anything in the letter that isn’t true. Letters are where inflated claims get caught, because they’re usually the first thing an interviewer re-reads before the call.

A fill-in sample you can adapt

Rather than staring at a blank page, adapt this skeleton — it follows the four-paragraph structure above and runs about 180 words:

Dear Ms. Harper,

Your job posting for the Growth Marketing Manager role stood out to me for one specific reason: the emphasis on lifecycle programs. That is the work I have spent the last five years doing.

At BrightWave, I owned the trial-to-paid journey for a B2B SaaS product. I rebuilt the first-week onboarding sequence, launched three behavior-triggered email flows, and worked weekly with the product team on activation experiments.

The measurable result: trial-to-paid conversion rose 18% over two quarters, and month-one churn fell by a third. I would bring that same evidence-first approach to your funnel.

I would welcome a conversation — my resume is attached, and I am available at your convenience.

Best regards,
Alex Rivera

Notice what is absent: no “I am a hard-working individual”, no repeated resume bullets, and no sentence that would survive swapping in a different company name.

Finding the hiring manager's name

A named greeting is one of the cheapest advantages in job searching. Try this order: check the job posting itself (many include a contact), look at the company’s team page, search LinkedIn for the department head, and check the email signature of any recruiter who contacted you. If you genuinely cannot find a name, “Dear Hiring Team” is a respectable fallback — just avoid “To whom it may concern”, which signals a template.
