You’ve polished your resume. The bullet points are tight. The formatting is clean. You hit “submit” on an application and—wait—there’s a cover letter field too.

And it’s optional.

Tempting to skip it, right? But here’s the thing: a good cover letter still matters. Not the kind that says “I’m writing to apply for the position of…” and then just lists everything that’s already on your resume. That’s a waste of everyone’s time.

A killer cover letter does something different. It fills in the gaps. It adds context. It shows the person behind the bullet points.

Here’s how to write one that actually works.

Match the Tone—But Make It You

You’d be surprised how many people send the exact same cover letter to a startup, a bank, and a nonprofit. That almost never works.

Read the job description. Look at the company’s website. Are they formal? Playful? Straight to the point? Your cover letter should feel like it belongs to their world. Not in a fake way—just in a “I did my homework” kind of way.

That said, don’t lose your voice. If you’re not a “passionate synergy-driven go-getter,” don’t write like one. It’ll read weird. Honestly? Recruiters can smell inauthenticity from a mile away.

Tell a Story Your Resume Can’t

Your resume shows what you did. Your cover letter can show how you did it—and why it mattered.

Maybe you increased sales by 30%. Great. Your resume already says that. But the cover letter is where you can explain that you inherited a team that was totally burned out, rebuilt their confidence, and turned things around in six months. That’s context. That’s human.

One engineer I know got a job largely because of this line in his cover letter:

“I spent two years maintaining legacy code no one else wanted to touch. It taught me patience, how to read other people’s bad decisions, and that clean code isn’t just nice—it’s necessary.”

That’s not a resume bullet. That’s a story.

Don’t Just Flatter Them—Connect the Dots

It’s fine to say you admire the company. But everyone says that. What sticks is when you show why you admire them—and how it connects to you.

Instead of:

“I’ve always admired Acme Corp’s innovative approach.”

Try:

“I’ve been following Acme Corp since your 2022 redesign. I was working on a UX overhaul at the time, and your approach to accessibility made me rethink my own assumptions about user testing.”

Now it’s specific. Now it’s personal. Now it’s not just flattery—it’s a connection.

Keep It Tight. Like, Really Tight.

No one reads long cover letters. Not because they’re lazy—because they’re busy. Three or four short paragraphs is plenty.

Here’s a structure that works more often than not:

  • Paragraph 1: Why this role, in one sentence. Maybe something recent that caught your attention.
  • Paragraph 2: A specific example of work you’ve done that relates directly to the job. Not everything—just one thing.
  • Paragraph 3: Why this company, specifically. What makes them different in your eyes.
  • Paragraph 4: A short close. Something like “I’d love to chat about how my experience with X could help with Y.”

That’s it. You’re done.

The Little Stuff Matters

Spelling errors. Obviously. But also: names. Double-check the hiring manager’s name. If you can’t find it, “Dear Hiring Manager” is fine. “To Whom It May Concern” feels like a relic from 1998.

And file format? Always PDF. Unless they ask for something else.

One more thing: if you’re emailing it, don’t just attach the file and hit send. Write a short note in the body too. Something like “Hey [Name], here’s my application. I particularly wanted to call out [one thing] because…” It’s small. But it shows you’re a real person.

When in Doubt, Ask Yourself: Would I Want to Read This?

Before you send it, read your cover letter out loud. Does it sound like you? Would you keep reading if you were on the other side?

If it feels like a chore to get through, it probably is. Cut the fluff. Tighten the sentences. Let your actual voice show up.

The best cover letters don’t feel like cover letters. They feel like someone saying: Here’s who I am. Here’s what I’ve done. Here’s why this feels right.

And sometimes, that’s exactly what gets you in the door.
