A cover letter introduces you to an employer and explains why you are a good fit for a particular role. A resume lists facts, while a letter connects them to the job. Conventions vary by country and employer, so always follow the instructions in the posting.
Key takeaways
- Tailor each letter to the role and the organisation.
- Keep it short, usually one page or about 250 to 400 words.
- Use two or three specific examples that match what the employer needs.
- Be honest and avoid copying generic templates.
- Proofread carefully and send in the format requested.
Step 1: read the job posting
Highlight the main responsibilities and required skills. Ask what problem the employer wants solved. Research the organisation: its work, values, recent news and culture. This helps you write something specific and shows genuine interest.
Step 2: address it properly
If possible, address the letter to a named person, such as the hiring manager. A quick look at the company website or professional profiles may reveal a name. If you cannot find one, "Dear Hiring Manager" is acceptable. Avoid "To whom it may concern" if you can.
Step 3: open with purpose
The first paragraph should say which role you are applying for and give a short reason why you are interested or why you are a good match. Avoid starting with a generic line such as "I am writing to apply for the position." You might begin with a short statement of enthusiasm connected to the organisation's work, followed by the role.
Step 4: show evidence
In one or two middle paragraphs, connect your experience to the employer's needs. Choose two or three relevant achievements and describe them briefly with specific details. For example, instead of "I have strong communication skills," write "I coordinated a volunteer team of twelve for a community event and wrote the weekly updates that kept everyone informed." Use real figures only if they are accurate. Do not simply repeat your resume. Add context, motivation and the story behind a result.
Step 5: address gaps carefully
If you are changing careers or have a gap, you can briefly explain how your skills transfer or what you have done since, without over-apologising. Focus on what you can bring.
Step 6: close confidently
Thank the reader, express interest in discussing the role further and mention how you can be reached or that you have attached your resume. A simple, courteous ending is enough: "Thank you for considering my application. I would welcome the chance to discuss how I could contribute to your team."
Format and tone
- Use a clear, professional layout with consistent fonts and spacing.
- Write in plain, positive language, and keep sentences short.
- Match the tone to the employer: slightly more formal for law or finance, warmer for some creative or non-profit settings.
- Save as a PDF unless told otherwise, and name the file clearly, such as your name and "cover letter."
Check before sending
- Is the employer's name spelled correctly, and is the role correct?
- Have you removed text copied from other letters?
- Are there any spelling or grammar errors? Reading aloud helps, and asking someone else to read it is even better.
- Does every claim reflect the truth?
A note on AI tools
Tools can help brainstorm or edit, but a letter that sounds generic is easy to spot. Make sure the final text reflects your real experience and voice.
A sample structure
A cover letter works well in four short paragraphs. The first states the role and one strong reason you are applying: for example, I am writing to apply for the project coordinator role, which combines my experience organising community events with my interest in your organisation's education work. The second paragraph gives your most relevant achievement in two or three sentences, with a concrete result. The third adds a second strand, such as a skill or value that matches what the posting asks for. The fourth closes by thanking the reader and saying you would welcome a conversation. Each paragraph should earn its place by showing evidence, not repeating adjectives.
Tailoring for different situations
Different situations call for a different emphasis. If you are changing careers, explain the thread that connects your past work to the new field, focusing on transferable skills such as communication, project management or analysis. Recent graduates can draw on projects, internships, volunteering and part-time jobs, describing responsibilities and outcomes. If you are applying for an internal role, mention achievements within the organisation and your understanding of its goals. If you are returning after a break, you can mention it briefly and positively, then focus on current readiness.
Digital applications
Most applications are now submitted online, and many employers use applicant tracking systems that store and sort applications. Use a clean layout, standard headings and a common font, and avoid text boxes and graphics that may not be read correctly. Match key terms from the posting where they truthfully apply, but write for a human reader first. Save your letter with a clear file name, such as your name and the role, and submit in the requested format. If you email the letter, put a short, polite message in the body and attach the file, or paste the letter into the email as instructed.
Mistakes that sink letters
Several errors recur. Sending a generic letter that could be for any employer shows little interest. Spelling the company or contact name wrongly gives a poor impression. Repeating your resume line by line wastes space, and long paragraphs make the letter heavy to read. Overblown claims without evidence, a negative tone about a past employer and mentioning salary or benefits too early can also hurt. Always proofread, preferably after a break, and ask someone to read it.
Differences between countries
Expectations vary. In the United States, a one-page letter with a confident tone is common. In some European countries, letters can be slightly longer and more formal, and in some regions, a photo and personal details are expected on a CV, though they are discouraged elsewhere. If you are applying abroad, look at examples from that country and follow the instructions in the posting.
Frequently asked questions
Do I always need a cover letter?
Not always. Follow the posting. If it is optional, a good letter can still help.
How long should it be?
Usually one page or less.
Should I mention salary?
Only if the posting asks for it.
Should I use a template for my cover letter?
Templates can help with layout and structure, but copying wording from one makes a letter sound generic. Use a template as a guide, and write your own content using specific examples from your experience.
What should I write if I have no direct experience?
Focus on transferable skills and evidence from studies, volunteering, projects or other jobs. Show enthusiasm and explain what you have done to learn about the field, and be honest about your level.
Do recruiters really read cover letters?
Practices vary. Some read every one, while others skim or skip them, especially when many people apply. A short, well-targeted letter can help you stand out, and it is essential when the posting requires one.
