You have spent hours on your CV. You have checked the formatting three times. Your experience lines up with the job description almost perfectly.
Then you scroll down and see it. Please include a cover letter with your application.
Suddenly that confidence disappears. You open a blank document and just stare at it, wondering where to even begin.
If this sounds familiar, you are not alone. Most job seekers find cover letters harder to write than the CV itself. But once you understand what a cover letter actually is and what it needs to do, the whole thing becomes much less intimidating.
So What Exactly Is a Cover Letter
A cover letter is a one page document you send alongside your CV when applying for a job. But calling it just a document undersells what it actually does.
Your CV tells employers what you have done. Your cover letter tells them why you are the right person for this specific role. It connects your experience to their needs. It shows how you think and how you communicate. It gives them a sense of who you are beyond a list of job titles and dates.
Think of it this way. Your CV gets you into the pile of qualified candidates. Your cover letter is what gets you pulled out of that pile and into the interview room.
In competitive job markets, whether you are applying in Lagos or London or anywhere else, a strong cover letter helps you stand out when dozens of other candidates have similar qualifications on paper.
Why Employers Still Care About Cover Letters
You might wonder why cover letters still exist. With LinkedIn profiles and one click applications, they can feel like a relic from another era.
But hiring managers keep asking for them because they reveal things a CV simply cannot.
A tailored cover letter shows genuine interest. Anyone can mass apply to fifty jobs in an afternoon. Taking the time to write something specific signals that you actually want this particular role at this particular company.
It also demonstrates how you communicate. Can you write clearly. Can you make a persuasive case for yourself. Can you be concise. These are skills employers care about, and your cover letter puts them on display before you have even walked into an interview.
Then there is the question of fit. Your tone, your approach, the way you frame your experience, all of this gives employers a glimpse of how you might fit within their team.
And if your career path has any gaps or transitions or unconventional turns, a cover letter gives you space to explain them on your own terms rather than leaving employers to guess.
A professional cover letter is not just a formality. It is a chance to make your case before anyone has even looked at your CV properly.
What Should a Cover Letter Look Like
Before anyone reads a single word, they notice how your letter looks on the page. A cluttered or messy layout can undermine even the best writing, so presentation matters.
Keep it to one page. Three or four paragraphs is ideal. Hiring managers are busy people with dozens of applications to review, and they appreciate candidates who respect their time.
Use a clean, readable font. Arial, Calibri, or Georgia all work well. Stick to 10 or 12 point size. Save the creative fonts for design portfolios.
Standard one inch margins keep things looking professional without making the page feel empty. Single space your paragraphs and leave a line break between each section so the text does not feel like a wall.
Always save and send as a PDF unless the employer specifically asks for a Word document. PDFs preserve your formatting across different devices and operating systems, so what you see is what they see.
The goal is clean and scannable. You want the hiring manager to be able to read through quickly without their eyes glazing over.
The Cover Letter Format That Actually Works
Every strong cover letter follows a logical structure. Not because you need to be formulaic, but because a clear flow makes your case easier to follow.
Start with a header that includes your name, phone number, email, and LinkedIn profile if relevant. Try to match the style of your CV header so everything looks cohesive. Below that, add the date and the company details.
For your greeting, use the hiring manager's name if you can find it. Check the job posting, the company website, LinkedIn. If you genuinely cannot find a name after searching, Dear Hiring Manager works fine. Just avoid To Whom It May Concern. It sounds impersonal and a bit outdated.
Your opening paragraph is your hook. State what role you are applying for and grab their attention immediately. Skip the generic openings like I am writing to apply for the position of. Everyone writes that. Instead, lead with something specific. Why are you excited about this company. What caught your attention about the role. Maybe you have a relevant achievement that connects directly to what they need.
The body of your letter is where you make your case. This is not the place to repeat your CV. Instead, pick two or three achievements that are directly relevant to the job and explain how they show you can solve the employer's problems. Use specific numbers where you can. Percentages, revenue figures, team sizes, timelines. Concrete details are more convincing than vague claims.
Your closing paragraph should reiterate your enthusiasm and include a clear call to action. Say you would welcome the chance to discuss the role further. Thank them for their time. Keep it brief.
Sign off with something professional. Kind regards or Best regards both work. Then your full name.
Mistakes That Kill Otherwise Good Cover Letters
Even strong candidates trip up on a few common errors.
Being too generic is the biggest one. If your cover letter could work for any job at any company with no changes, it is not doing its job. Hiring managers can tell when they are reading a template, and it makes them question how much you actually want this specific role.
Repeating your CV word for word is another mistake. Your cover letter should complement your CV, not duplicate it. Use it to add context and narrative, not to list the same bullet points in sentence form.
Making it all about yourself sounds counterintuitive, but your cover letter should really be about them. Frame everything in terms of what you can do for the employer, not just what you want from the job.
Typos and spelling errors are obvious but still worth mentioning. Nothing undermines your credibility faster than mistakes in a document that is supposed to showcase your communication skills. Proofread it. Then proofread it again. Then ask someone else to read it.
Going over one page suggests you cannot communicate concisely, which is not the impression you want to leave.
Do You Actually Need a Cover Letter Every Time
If the application asks for one, yes. Full stop.
If it says optional, still yes. Optional usually means we will notice if you do not include one. Candidates who skip the optional cover letter often get skipped themselves.
The only real exceptions are when the application system explicitly says not to include one, or when you are applying through a platform that does not support attachments.
When in doubt, write the cover letter. It takes time, but it is a low risk way to strengthen your application. The downside of including one is minimal. The downside of leaving it out could be a missed opportunity.
Bringing It All Together
A well written cover letter will not guarantee you the job. But it can guarantee you get noticed. When hiring managers are looking at a stack of applications from equally qualified candidates, the cover letter is often what tips the scales toward an interview.
The key is to treat it as a conversation starter. You are not trying to tell your entire career story. You are trying to say just enough to make them want to learn more.
So next time an application asks for a cover letter, do not panic. You know what it is. You know what it should look like. You know the format that works. Now it is just about sitting down and writing it.
And if you want help getting started, you can use app.instict.ai to generate a tailored cover letter for free. Just enter your details and the job you are applying for, and you will have a solid first draft in minutes. No more staring at a blank page wondering what to write.
