How to Write a Cover Letter That Gets Read

1. Why cover letters still matter

Cover letters are not universally required, but when they are requested, submitting without one is close to withdrawing your application. More importantly, when everyone else submitting has a similar level of experience to you, a cover letter is one of the few ways to differentiate yourself before an interview.

The letter does work the CV cannot do. A CV is a structured record; a cover letter is a voiced argument. It can explain why you are making a career change, why you are applying to this company rather than a competitor, why a gap in your employment was a deliberate choice, or why your non-traditional background is actually an asset for this specific role.

Recruiters who read cover letters are often the ones who read them precisely because they want to understand whether there is a human behind the CV. A great cover letter gets you on the interview shortlist when your CV alone might not have. A bad one confirms an already uncertain first impression. A missing one, when one was asked for, suggests you did not bother.

2. The one-page rule

A cover letter should never exceed one page. This is not an arbitrary convention — it reflects the time a recruiter has available. A one-page letter that is focused and specific will be read. A two-page letter will be skimmed and is likely to create an impression of someone who does not know what to cut.

One page means roughly three to four short paragraphs of focused prose, or around 300–400 words. Every sentence should be earning its place. If you can remove a sentence and the letter still makes sense, remove it. If a paragraph could describe any applicant to any company, it is filler and should go.

The discipline of a one-page limit forces you to make decisions about what actually matters. Those decisions are part of what the letter is evaluating — if you cannot choose what is most relevant to say about yourself in 400 words, a hiring manager will wonder how you will prioritise in the role.

3. The opening line — hook, not a statement of intent

The single most common opening line in cover letters is a waste of a sentence: 'I am writing to apply for the position of [role] at [company], as advertised on [job board].' The recruiter posted the job. They know what it is. This sentence communicates nothing except that you have correctly identified the role you are applying for, which is a very low bar.

A strong opening line gives the reader an immediate reason to keep reading. It might be a specific connection to the company's work: 'I have used your API to build three production applications over the past two years, so when I saw a senior engineer opening I applied the same day.' Or it might establish your positioning immediately: 'After eight years as a litigation solicitor, I want to move into commercial legal roles — and this position, which spans both contentious and advisory work, is exactly the transition I have been preparing for.'

The hook does not have to be dramatic. It just has to be specific to this application and this reader. A recruiter who sees that you have a genuine connection to the role, the company, or the problem they are hiring for is far more likely to read the next paragraph than one who sees a sentence that could have been auto-filled.

4. The body — your fit for the role with specific evidence

The body of the letter is where you make the case. Not a summary of your CV — the letter is not a prose version of your CV. The case is: here is the specific intersection between what this role requires and what I have actually done. Pick two or three points of genuine fit and develop each briefly.

The structure for each point is the same: name the requirement the job has, provide a specific example from your history that demonstrates you have met a similar requirement, and connect the two. 'The role description mentions building and maintaining relationships with procurement teams across multiple territories. In my most recent position I was the sole account manager for six European clients with combined annual spend of €4.2m — I kept renewal rates above 95% for three consecutive years through quarterly reviews and a structured escalation process I designed.'

You do not need to cover every requirement. You need to cover the two or three that are most important or hardest to demonstrate through a CV alone. Choose the points where you have a specific story, not just a claim.

5. The close — what you want to happen next

The closing paragraph should do two things: express genuine interest in the next step (not performative enthusiasm — real specificity), and make it easy for the recruiter to act. A clean close might look like: 'I would welcome the opportunity to discuss how my background in regulated financial services maps to this role. I am available for a call any time next week — my number is on the CV, or you can reach me at the email address above.'

Avoid submissive closings like 'I hope you will consider my application' or 'I would be grateful for the opportunity to be considered'. These phrases suggest low confidence and, subtly, low status. You are not hoping to be considered; you are offering something of value and making it easy for them to access it.

Also avoid false urgency: 'I look forward to hearing from you soon' is fine; 'Please do not hesitate to contact me at your earliest convenience' is padding. Close with a single confident, specific sentence and then stop.

6. What never to write

Several specific things reliably reduce your chances of being called. Opening with 'I am a passionate and dedicated professional' — passion is claimed by everyone and means nothing without evidence. Sentences like 'I believe I would be a great asset to your team' — believe is weak, 'great asset' is vague, and the whole phrase is about what you believe rather than what you can demonstrate.

Do not describe the company's mission statement back to the company. Recruiters have read their own about page. What they want to see is a specific connection: not 'I admire your commitment to sustainability' but 'I have spent the past three years doing carbon accounting for manufacturing clients, which is directly relevant to the scope of your net-zero reporting project'.

Do not explain that you are a 'quick learner' or 'work well independently and as part of a team'. These are the phrases that signal a letter written in a hurry with no specific thought about the role. Every one of these clichés is a missed opportunity to say something true and specific about yourself.

7. Email vs PDF — how to format and send

When an application is submitted through an online portal, the cover letter is usually a separate PDF upload alongside the CV. In this case, format it like a professional letter: your name and contact details at the top, the hiring manager's name and company if you know them, the date, and the letter in full. Save it as PDF with a clear filename (YourName-CoverLetter.pdf).

When you are applying directly by email, the cover letter is often the body of the email itself — shorter, slightly more conversational in tone, but still focused and specific. Attach the CV. The email subject line should be clear: 'Application — Senior Product Manager, Ref 2026-PM-04' or similar. Do not use generic subject lines like 'Job Application' — they look like spam and sort to the bottom of a recruiter's inbox.

If the job posting does not specify a format, PDF is generally safer: it looks the same on every device, cannot be accidentally edited, and signals that you formatted it deliberately rather than firing off a quick email.

8. Tailoring checklist before you send

Cover letters fail most often because they are not tailored — they were written for one application and reused with minimal changes. Run through this before every submission.

• Opening line is specific to this role and company — no generic 'I am applying for' opener.
• Company name and role title are correct throughout (copy-paste errors are common and immediately disqualifying).
• Body paragraphs reference specific requirements from this job description, not generic ones.
• At least one piece of evidence is a specific, quantified achievement relevant to this role.
• No sentence could be in a letter for a different company or a different role without editing.
• Length is one page or under (300–400 words).
• No clichés: no 'passionate', no 'dedicated', no 'excellent communication skills', no 'team player'.
• Closing sentence specifies how and when you are available — not 'I hope to hear from you'.
