To write a cover letter, use four short paragraphs: open with the role you want and one sentence that proves you are a strong fit, back that up with two or three specific achievements that match the job description, explain why you want to work at this particular company, and close with a confident request for a conversation. Keep it between 250 and 400 words, address it to a real person when possible, and never repeat your resume line by line.
The rest of this guide breaks down each paragraph, shows a complete example, and covers the mistakes that get cover letters skipped.
What is a cover letter actually for?
Your resume shows what you have done. Your cover letter connects those facts to the specific job in front of the reader. It answers three questions a hiring manager has after glancing at your resume:
- Why are you applying for this role?
- Which of your experiences matter most for it?
- Why here, and not anywhere else?
A good cover letter is an argument, not a biography. Every sentence should help the reader say yes to an interview.
How should you structure a cover letter?
Here is a simple structure that works for nearly every industry and seniority level.
| Section | Length | What it does |
|---|---|---|
| Header and greeting | 4-6 lines | Your contact details, the date, and a named greeting |
| Opening hook | 2-3 sentences | Names the role and gives your single strongest reason to keep reading |
| Proof of fit | 3-5 sentences or 3 bullets | Matches your achievements to the job's top requirements |
| Why this company | 2-3 sentences | Shows you know who they are and why it matters to you |
| Close | 2 sentences | Asks for a conversation and thanks the reader |
How do you write a strong opening paragraph?
Skip "I am writing to apply for..." The reader already knows that. Lead instead with the role and a concrete reason you are qualified.
Weak: "I am writing to express my interest in the Marketing Manager position I saw on your website."
Strong: "I'm applying for the Marketing Manager role because I've spent the last four years doing exactly what your posting describes: growing organic traffic for B2B software companies. At Brightline, I took the blog from 8,000 to 65,000 monthly visitors in 18 months."
The strong version names the role, mirrors the job description, and drops a number in the first two sentences.
What goes in the middle paragraph?
This is where you prove the claim from your opening. Pick the two or three requirements from the job post that matter most, then match each one with a short achievement.
A simple way to do this:
- Highlight the top requirements in the job description.
- For each, find one result from your past that demonstrates it.
- Write it with a number or a clear outcome.
Bullets are fine here and often easier to scan than a dense paragraph. If you have not quantified your achievements yet, start with your resume bullets. Our guide on how to write a resume walks through turning duties into measurable results.
How do you show you actually want this job?
Generic praise like "your company is an industry leader" signals a mass application. Instead, mention something specific:
- A product you use and what you like about it
- A recent launch, expansion, or announcement
- The company's mission and a personal connection to it
- Something specific in the job post, such as the team structure or a tool they use
One or two sentences is enough. The goal is to show you made a deliberate choice.
How should you close a cover letter?
End with a short, confident request for next steps. Avoid sounding passive ("I hope to hear from you") or pushy ("I will call you on Monday").
Example: "I'd welcome the chance to talk about how I could help your team hit its growth goals this year. Thank you for your time and consideration."
Then sign off with "Sincerely," or "Best regards," followed by your full name.
What does a full cover letter example look like?
Here is a complete example for a mid-level marketing role. Notice how each paragraph has one job.

Dear Priya Shah,
I'm applying for the Content Marketing Manager role at Northwind Analytics. For the past four years I've built content programs for B2B software companies, and at Brightline I grew organic traffic from 8,000 to 65,000 monthly visitors in 18 months while cutting cost per lead by 40 percent.
Your posting emphasizes SEO strategy, team leadership, and content that drives pipeline. Here is how my experience lines up:
- SEO strategy: Built a keyword and topic-cluster plan that produced 30 first-page rankings for high-intent terms.
- Team leadership: Managed three writers and a freelance network of eight, shipping 12 long-form pieces per month.
- Pipeline impact: Launched a gated report series that generated 1,200 marketing-qualified leads in its first quarter.
I've used Northwind's dashboards at two previous jobs, and your recent push into self-serve analytics for small teams is exactly the kind of audience I love writing for. I'd be excited to help explain that product to the people who need it most.
I'd welcome the chance to discuss how I could help Northwind grow its organic pipeline this year. Thank you for your time and consideration.
Best regards,
Jordan Lee
That letter is about 270 words. It is specific, scannable, and tied tightly to the job post. For more samples by role and industry, browse our cover letter examples.
What mistakes should you avoid in a cover letter?
- Repeating your resume. Highlight and interpret, do not copy.
- Making it about you. Frame your goals in terms of what the employer gets.
- Using a generic greeting. "To whom it may concern" feels outdated.
- Going long. If it spills onto a second page, cut it.
- Forgetting to proofread. Typos in a letter about attention to detail are hard to recover from.
- Mismatched design. Your cover letter should use the same fonts and header as your resume so they look like a set.
How can you write cover letters faster without sounding generic?
Keep a document of your best proof points, each tied to a skill, and reuse them as building blocks. For each new application, swap in the two or three that match the posting, then rewrite the opening and the "why this company" paragraph from scratch.
If you want help with a first draft, the JotResume cover letter builder can generate a letter from your resume and the job description, which you can then edit in your own voice. It also matches the styling of your resume templates so your application looks consistent. Whatever tool you use, always edit the draft so it sounds like you and includes details only you would know.
The bottom line
A cover letter does not need to be long or clever. It needs to be specific. Name the role, prove your fit with two or three real results, show why this company matters to you, and ask for the conversation. Do that in under 400 words, and your letter will be read rather than skimmed.
