A great cover letter still opens doors. While some applications skip it, many hiring managers read the cover letter first to decide whether your resume is worth a closer look, and a sharp, tailored letter is one of the fastest ways to stand out in a crowded field. The problem is that most people either repeat their resume or write a generic template that says nothing. This guide walks through exactly what a cover letter is, the structure that works, how to write each section with examples, the mistakes to avoid, and how to make sure it lands, whether you write it yourself or have our writers do it for you.
What is a cover letter, and why does it matter?
A cover letter is a brief, personalised message that introduces you, connects your experience to one specific job, and asks for the interview. Where your resume is a structured record of what you have done, the cover letter is the argument for why it matters to this employer. A strong letter does three things: it shows you understand the role, it proves you can deliver results with one or two specific examples, and it conveys genuine interest in the company. Done well, it turns a pile of similar resumes into a clear first choice.
The structure of a cover letter
| Section | What it does |
|---|---|
| Header | Your name and contact details, matched to your resume |
| Greeting | Addresses the hiring manager by name where possible |
| Opening paragraph | Names the role and hooks the reader in the first two lines |
| Body (one or two paragraphs) | Proves your fit with specific, quantified achievements |
| Closing paragraph | Restates interest and asks for the interview |
| Sign-off | A professional close and your name |
How to write each section (with examples)
Start with a clean header and greeting
Use the same header as your resume so your application looks consistent. Then address a real person. Check the job posting, the company website, or LinkedIn for the hiring manager’s name, and only fall back to a role-based greeting if you truly cannot find one.
Do: “Dear Ms. Alvarez,” · If unknown: “Dear Hiring Manager,” · Avoid: “To Whom It May Concern”
Hook the reader in the opening
Name the exact role and lead with energy and a headline reason you are a fit. Skip “I am writing to apply for.” Make the first two lines earn the next paragraph.
Do: “Your posting for a Marketing Coordinator caught my eye because growing small-team campaigns is exactly what I did to lift qualified leads 40% last year.”
Prove your fit in the body
Pick the two or three requirements that matter most in the posting and answer each with a specific, quantified example. This is where you show, rather than claim, that you can do the job.
Do: “When my team faced a 30% support backlog, I redesigned the workflow and cut response time from 48 to 12 hours.”
Show you know the company
One genuine sentence about why this employer, not just any employer, separates you from the generic pile. Reference a product, value, or recent milestone that connects to your goals.
Do: “I admire how your team pairs design with accessibility, and I would love to bring my testing background to that mission.”
Close with confidence and a call to action
Restate your interest in one line, thank them, and ask for the next step. End with a professional sign-off and your name.
Do: “I would welcome the chance to discuss how I can help your team hit its goals. Thank you for your time, and I look forward to speaking. Sincerely, Jordan Lee”
A short cover letter example
Dear Ms. Alvarez, Your posting for a Customer Success Specialist stood out because turning at-risk accounts into loyal customers is exactly what I do. At Brightline, I managed a book of 120 accounts and lifted renewal rates from 82% to 94% in a year by building a proactive check-in system. I am drawn to your focus on customer outcomes and would love to bring that same ownership to your team. I would welcome the chance to talk. Thank you for your time. Sincerely, Priya Nair
Common cover letter mistakes to avoid
Most weak cover letters share the same flaws: they repeat the resume word for word, they stay generic enough to send anywhere, they focus on what the writer wants instead of what the employer needs, and they run too long. Avoid typos and the wrong company name at all costs, keep it to one page, and never open with a tired line like “I am writing to apply.” Every sentence should earn its place.

Our writers craft a tailored, recruiter-ready cover letter matched to your resume and the exact job you want, so you can apply with confidence.
Make sure it passes the ATS
Many employers scan cover letters and resumes with applicant tracking software before a human reads them. Keep the formatting simple, use a standard font, save as PDF or Word as requested, and mirror the key terms from the job posting where they truthfully apply. Then check your resume too. Run it through our free ATS resume checker to see your score and the keywords you are missing before you apply.
Frequently asked questions
How long should a cover letter be?
One page, and usually between 250 and 400 words across three or four short paragraphs. Hiring managers skim, so make every line count and never spill onto a second page.
Do I need a different cover letter for every job?
Yes. The whole point is tailoring. You can reuse a strong structure, but the opening, the examples, and the company sentence should change for each role. Generic letters are easy to spot and easy to reject.
What if I have no work experience?
Lead with transferable skills from school, volunteering, or projects. See our full guide on writing a cover letter with no experience, and browse cover letter examples you can adapt.
Should the cover letter repeat my resume?
No. It should complement your resume by explaining the story and the impact behind one or two achievements, not list them again. Pair it with a strong resume, and see our resume samples for the format.
