Cover Letter Writing Guide — Beautifully formatted cover letter with pen

Everyone hates writing cover letters. You know it, I know it, and hiring managers know it too. Which is exactly why a genuinely good one stands out so much. When 80% of applicants either skip the cover letter or submit something that could have been written by a robot in 2019, yours just needs to be human, specific, and interesting.

This guide will show you exactly how to structure a cover letter, what to write in each section, and how to avoid the mistakes that get most cover letters tossed in the bin.

Why Cover Letters Still Matter

In a world of one click applications and LinkedIn Easy Apply, you might wonder if cover letters are even worth the effort. The short answer is yes. Here is why:

  • 83% of hiring managers say cover letters influence their decision (Robert Half, 2024)
  • They give you a chance to explain context your CV cannot (career changes, gaps, relocations)
  • They show you actually researched the company and care about this specific role
  • They let your personality come through in a way a list of bullet points never can

Think of your CV as the facts, and your cover letter as the story. Both matter, but the story is what makes people care.

The Perfect Cover Letter Structure

Every great cover letter has four parts. No more, no less. This is not the time to write a five paragraph essay or a three page autobiography.

Paragraph 1: The Hook

Your opening paragraph has one job: make the reader want to keep reading. Do not start with "I am writing to apply for the position of..." because that is the most boring sentence in the English language. They already know you are applying. Instead, lead with something that catches attention.

❌ Boring opening

Dear Sir or Madam, I am writing to express my interest in the Marketing Manager position at ABC Company. I believe my skills and experience make me a strong candidate for this role.

✅ Engaging opening

When I saw that Monzo is hiring a Marketing Manager to lead their B2B growth team, I got genuinely excited. I have spent the last three years doing exactly that at a Series B fintech, growing the pipeline from £500K to £3.2M annually, and the chance to do it at a brand I personally use every day feels like a perfect fit.

See the difference? The good opening is specific to the company, mentions a concrete achievement, and shows genuine enthusiasm. It took 30 extra seconds to write and it is infinitely more compelling.

Paragraph 2: Why You Are Great

This is where you connect your experience to what the role needs. Do not just repeat your CV. Instead, pick two or three of your most relevant achievements and explain why they matter for this specific role.

The formula is simple: What challenge you faced → What you did → What happened (with numbers).

💡 The Mirror Technique: Read the job description carefully and highlight the top 3 requirements. Then write your second paragraph addressing exactly those 3 things with evidence from your experience. This shows the hiring manager you have read the posting and are not just spray and praying applications.

Paragraph 3: Why This Company

This is where most people fail completely. "I admire your company's commitment to excellence and innovation" means nothing. Every company thinks they are excellent and innovative. You need to mention something specific.

Do your homework. Read their blog, check their LinkedIn posts, look at their recent projects or product launches. Then reference something specific that genuinely interests you. If you cannot find anything interesting about the company, you probably should not be applying there.

✅ Specific company research

I was particularly impressed by your recent expansion into the DACH market. Having lived in Berlin for two years and led localisation efforts for three SaaS products, I understand the nuances of entering German speaking markets and would love to bring that experience to your team.

Paragraph 4: The Close

End with confidence, not desperation. "I would welcome the opportunity to discuss how my experience could contribute to your team" is fine. "I am begging you to please consider my application" is not.

Include a clear call to action: say you are available for an interview, mention your notice period if relevant, and thank them for their time. Keep it to two or three sentences.

A Full Cover Letter Example

Complete cover letter (Marketing Manager role)

Dear Sarah,

When I saw that Monzo is hiring a Marketing Manager to lead B2B growth, I knew I had to apply. I have spent the last three years building the B2B marketing function at a Series B fintech from the ground up, growing qualified pipeline from £500K to £3.2M annually. The chance to bring that experience to a brand I genuinely admire feels like a natural next step.

In my current role at PayFlow, I lead a team of four across content, paid acquisition, and partner marketing. We launched an ABM programme targeting enterprise clients that delivered a 340% ROI in its first year. I also built our webinar strategy from zero to 2,000 monthly registrants, which became our highest converting lead source. I am confident I could replicate and scale similar programmes at Monzo.

What excites me most about this role is Monzo's recent push into business banking. Having watched the product evolve from a personal spending card to a serious business platform, I think the B2B marketing opportunity is enormous. I would love to be part of the team that makes Monzo the default choice for UK businesses.

I am available to start with four weeks notice and would welcome the chance to discuss this further. Thank you for your time.

Best regards,
James Chen

The Ten Biggest Cover Letter Mistakes

1. Starting with "To Whom It May Concern." Find the hiring manager's name. Check LinkedIn, the company website, or even call reception and ask. If you truly cannot find it, "Dear Hiring Team" is better.

2. Repeating your CV verbatim. Your cover letter should complement your CV, not duplicate it. Add context, personality, and motivation that your CV cannot convey.

3. Making it all about you. The best cover letters balance what you want with what the company needs. "I want to grow my career" is fine, but "Here is how I can help you grow revenue" is better.

4. Being too long. One page. 250 to 400 words. Three to four paragraphs. That is it. Respect the reader's time.

5. Apologising for what you lack. "Although I don't have experience in..." immediately draws attention to a weakness. Focus on what you do bring and let the hiring manager decide if it is enough.

6. Using a template without personalising it. Templates are great starting points, but if you send one without changing the company name, role title, and specific details, you will look lazy. Or worse, you will accidentally leave in another company's name.

⚠️ Real Disaster: Hiring managers regularly receive cover letters that mention the wrong company name. This is an instant rejection. Triple check before sending.

7. Being too casual. There is a difference between personable and unprofessional. Emojis, slang, and excessive exclamation marks do not belong in a cover letter, even for a startup.

8. Not including a call to action. End with a clear next step. "I would welcome the opportunity to discuss this role" is direct and professional.

9. Forgetting to proofread. One typo in your cover letter is worse than one typo on your CV because the cover letter is supposed to show your attention to detail. Read it aloud before sending.

10. Using the same letter for every application. Mass produced cover letters are obvious. Customise at least the opening, the company specific paragraph, and the role title for every single application.

When to Skip the Cover Letter

Despite everything above, there are rare situations where a cover letter is genuinely not needed:

  • The application system literally has no field to upload one
  • The job posting explicitly says "do not send a cover letter"
  • You are applying through a referral and the hiring manager already knows you

In every other case, write one. It takes 20 to 30 minutes and could be the difference between an interview and silence.

Key Takeaways

  • Structure your letter in 4 paragraphs: hook, your value, why this company, close
  • Never start with "I am writing to apply for..."
  • Reference something specific about the company
  • Keep it under one page (250 to 400 words)
  • Do not repeat your CV. Add context and personality
  • Customise every single cover letter
  • Proofread twice, then proofread again

Frequently Asked Questions

Do employers actually read cover letters?+

Yes, about 83% of hiring managers say cover letters are important when making hiring decisions (according to a Robert Half survey). However, they read them quickly, so the first paragraph needs to hook them immediately. A generic cover letter might not get read, but a well written, specific one absolutely will.

How long should a cover letter be?+

Three to four paragraphs, fitting on a single page. Aim for 250 to 400 words. Anything longer and you risk the hiring manager losing interest. Anything shorter and it looks like you did not put in effort. Think quality over quantity.

Should I write a cover letter if it is optional?+

Yes, almost always. When a job posting says "cover letter optional," it is often a test to see who goes the extra mile. Submitting a strong cover letter when others skip it gives you a competitive advantage. The only exception is if the application system genuinely does not have an upload field for one.

Can I use the same cover letter for every job?+

Absolutely not. A generic cover letter is almost worse than no cover letter at all. Hiring managers can spot a copy paste job from a mile away. You should customize at least the opening paragraph, the company name, the specific role, and the reasons why you want to work there for every application.

What should I not include in a cover letter?+

Do not repeat your CV word for word. Do not apologise for things you lack ("I know I don't have 5 years of experience but..."). Do not discuss salary expectations unless specifically asked. Do not write more than one page. And please do not start with "To Whom It May Concern" if you can find the hiring manager's name.

Should a cover letter be formal or casual?+

Match the tone of the company. If the job posting uses casual language and the company culture seems relaxed, a slightly conversational tone is fine. For corporate, legal, or financial roles, lean more formal. When in doubt, aim for professional but personable. Think "friendly colleague at a networking event" rather than "Victorian era letter writer."
