How to Write a Cover Letter: A Simple Guide With Examples
A lot of people dread the cover letter more than the resume itself. You stare at a blank page, write “I am writing to apply for,” and immediately want to give up. The good part is that a strong cover letter follows a pretty simple shape, and once you know it, the whole thing gets much faster. This guide breaks down how to write a cover letter that actually helps your application instead of just repeating your resume.
Do you even need a cover letter?
Honestly, it depends. Some applications make it required, some make it optional, and a few skip it entirely. Here's a simple rule: if there's a field for it, write one. A thoughtful cover letter rarely hurts you, and a missing one can read as low effort when other candidates bothered to include it. When it's clearly optional and you have something real to say about why you want the role, it's usually worth the ten minutes.
What a cover letter is actually for
Your resume shows what you've done. Your cover letter explains why it matters for this job, and why you want it. It's your chance to connect the dots that a list of bullet points can't, like why you're switching industries, what drew you to the company, or how a specific project lines up with what they need. Think of it as a short, direct note from you to the hiring manager, not a formal essay.
Before you write: do a little homework
The difference between a generic letter and a memorable one is usually five minutes of research. Before you write a word, find:
- The two or three things the job posting emphasizes most
- The hiring manager's name, if you can find it on LinkedIn or the company site
- One genuine reason you want to work there, beyond the paycheck
That last one matters more than people think. Hiring managers can tell the difference between “I want a job” and “I want this job.”
The structure of a strong cover letter
Almost every good cover letter follows the same five parts. Keep it to a single page, ideally three or four short paragraphs.
1. Header and greeting
Put your name and contact details at the top, matching your resume so the two look like a set. Then greet the person by name if you have it: “Dear Maria Lopez.” If you truly can't find a name, “Dear Hiring Manager” is fine. Avoid “To Whom It May Concern,” which feels dated.
2. The opening
Skip “I am writing to apply for the position of.” They know. Open with something specific that shows interest and a reason to keep reading.
I am writing to express my interest in the Marketing Coordinator position at your company.
When I saw that you're rebuilding your content team from the ground up, I knew I had to apply. I spent the last two years doing exactly that at a startup, and I'd love to bring it to a brand I already read every week.
3. The body
This is where you make your case. Pick one or two of your strongest, most relevant achievements and explain how they connect to what this employer needs. Don't list everything on your resume again. Choose the wins that map directly to the job and add a sentence of context the resume couldn't fit.
4. The closing
Briefly say why you're drawn to the company and what you'd bring, then make it easy for them to take the next step. One or two sentences is plenty.
5. Sign-off
Keep it simple. “Best regards” or “Thank you for your time” followed by your name does the job.
Show that you fit, don't just claim it
The weakest cover letters are full of adjectives. The strong ones use evidence. Instead of telling them you're organized and driven, show a quick example that proves it.
I am a highly motivated and detail-oriented professional with excellent communication skills.
In my last role I ran our weekly client reporting for 14 accounts, and not one ever missed a deadline. I like keeping a lot of moving parts on track, which is exactly what this role seems to need.
How long should a cover letter be?
Short. Aim for half a page to a full page, no more. Three or four tight paragraphs is the sweet spot. A hiring manager reading dozens of applications will quietly appreciate one that respects their time, and a long letter usually means you're padding rather than making a point.
Tailor every letter to the job
A cover letter you could send to any company is a cover letter that convinces no one. You don't have to rewrite it from scratch each time, but you do need to swap in:
- The company name and the specific role
- One real reason you want to work there
- The one or two achievements that line up best with this posting
Common cover letter mistakes
- Repeating your resume word for word.Add context and reasoning, don't just restate bullets.
- Making it all about you. Connect your story to what the employer actually needs.
- Going too long. If it spills past one page, cut.
- Forgetting to change the company name.It happens more than you'd guess, and it's an instant rejection.
- Being so formal it sounds robotic. Write like a real person who happens to be professional.

A good cover letter isn't complicated, but writing a fresh one for every application still adds up.

How long should a cover letter be?
Keep it to half a page or one page at most, usually three or four short paragraphs. Hiring managers read a lot of applications, so a tight, focused letter works better than a long one.

If the application has a field for one, write it. A thoughtful cover letter rarely hurts you, and skipping it can look like low effort when other candidates included one.
What should the first line of a cover letter say?
Skip 'I am writing to apply for.' Open with something specific that shows genuine interest in the role or company and gives the reader a reason to keep going.
Should I write a new cover letter for every job?
You don't have to start from scratch, but you should tailor each one. Swap in the company name and role, one real reason you want to work there, and the achievements that match the posting best.
