How to Write a Great Cover Letter (with Samples for Marketers)

Let’s be honest! Most marketers dread writing cover letters. So we end up using a generic template and swapping out the company name just because we find it easy. But the truth is a cover letter is your first real shot at standing out.

Not just as a marketer. But as a thinker. A doer. A problem-solver.

And you don’t need to write something long or fancy.

You just need to show three things:

  1. Why you make sense for the role
  2. Why they make sense for you
  3. One clear win that proves you can do the job

That’s it. No fluff. No big words. No overthinking. 

In this guide, I will walk you through the exact format you can follow step by step. Plus, I have added sample cover letters for every major marketing role. You can copy them, tweak them, and send them.

4-Step Cover Letter Writing Process

Writing cover letters can sometimes feel awkward, and you don’t want to sound too boring or too desperate. Sometimes, you are just not sure what to say. But a good cover letter can actually make a big difference. It helps you stand out and shows you care.

And it’s the easiest way to connect your skills to the company’s needs.

Let’s break it down step by step.

Step 1: Start with “Why You”

This is where you tell the company why you are the right person for the job. And no, you don’t need to be fancy or use big words. Just be open and honest. Start with who you are and what kind of marketer you are. For example, you can say:

  • I’m a performance marketer with 3 years of experience helping DTC brands grow through paid ads.

Now, add a sentence that connects your work with their brand.

  • I’m excited about this role because your brand reminds me of a skincare client I worked with - we doubled their ROAS in 4 months.

See! In two lines, you shared:

  1. What you do
  2. What kind of experience you have
  3. Why this job makes sense for you

Most importantly, you made it feel personal.

You showed them that your application is not just another random job application.

You made a connection between your past work and their current goals. That’s the goal of this first part: make the hiring manager think, Okay, this person gets what we do, and they have done something similar before.

You don’t have to list everything. One or two strong sentences are enough to grab their attention. Think of this as your hook. Your ad copy that makes them want to read more. It doesn’t tell them much about you if you skip this part or write something too generic.

>> So start with why you are the right fit, back it up with something real, and keep it short and human.

Step 2: Talk About “Why Them”

This is where you show the company that you have done your homework. You don’t need to write an essay. Just one or two sentences are enough to show that you care about this brand, not just any brand.

Think of it like this: hiring managers see tons of cover letters that all look similar. Most people write, “I’m excited to join your amazing company.” That doesn’t tell them anything. It feels copy-pasted. So instead, tell them something specific that shows you know them.

Here’s a good example:

I’ve been following your brand since your last campaign with [influencer name]. I loved how you mixed humor with storytelling—it’s the kind of marketing I enjoy doing, too.

This sentence works because it proves that you:

  • Know who they are
  • Understand how they market their products
  • Have a personal reason for wanting to work with them

You could also mention something from their blog, social media, ad campaign, or even a product you’ve used. Maybe you love their email copy or think their Instagram strategy is clever. Whatever it is, say it. Genuine interest stands out. 

This step is all about making the company feel seen. When you show that you understand their brand, you build trust. And trust makes them more likely to move your application forward.

>> Don’t be vague. Be specific and genuine, and show them why they matter to you.

Step 3: Share One Good Win

Now that you have said who you are and why you like the company, it’s time to show what you have done. Here is where you share one Aha win from your past work, just one. Don’t list everything from your resume. Pick one clear example that proves you can drive results.

Think of it like showing a case study but in one short paragraph. Here’s a simple example:

I ran a paid ads campaign in my last role for a new product launch. We hit 1 million impressions in the first 10 days, and the ROAS stayed above 4.5. I handled everything, from copy and creative to targeting and landing pages.

It works because it’s:

  • Specific
  • Easy to understand
  • Focused on real results

It tells the hiring manager you have done the work they are hiring for and shows that you can turn ideas into outcomes.

By keeping it short, you ensure they read it.

If you don’t have big numbers to share, that’s okay. Just pick a project where you made a difference. Maybe you improved email open rates. Or you helped redesign a landing page that boosted signups. Or you helped a small brand find its voice.

Just ensure you say what you did and what changed because of it.

This step is your proof. You have already said why you are a good fit. Now, you are showing.

>> So pick a good win, keep it simple, and make sure it relates to the role you are applying for.

Step 4: Keep It Short and Kind

Now, it’s time to wrap things up. You have already shown who you are, why you like the company, and what you have achieved. The ending doesn’t need to be long or fancy. Just keep it short, polite, and human.

A good closing line could be something like this:

Thanks for taking the time to read this. I’d love to chat more about how I can help your team. I am looking forward to hearing from you!

It works because it does three simple things:

  1. It shows gratitude.
  2. It makes it clear that you are open to a conversation.
  3. It ends on a warm, positive note.

You do not have to say things like I am the perfect candidate or Please consider me for this role. Those can sound a little too pushy or robotic.

A kind, honest thank-you is more powerful. Also, avoid writing a long paragraph at the end. The person reading your cover letter will probably get hundreds and thousands of resumes. Respect their time. Say what you need to say, then stop.

Think of this step as your way of saying, Hey, I am here, I am interested, and I would love to talk more... if you are open to it. That’s all you need.

>> Keep it short and kind, and leave with a good feeling.

Now, my sample cover letter from each step combined would be:

Hi [Hiring Manager's Name],
I am a performance marketer with 3 years of experience helping DTC brands grow through Facebook and Google ads. I am excited about this role because your brand reminds me of a skincare client I worked with last year—we doubled their ROAS in 4 months, and I loved the challenge of scaling a product with strong brand values.
