Let's be honest: most cover letters are terrible.
They're generic. They repeat the resume. They're filled with phrases like "I'm excited about the opportunity" and "I believe my skills make me a great fit." Recruiters skim them in seconds, if they read them at all.
But a good cover letter can actually help you—especially for PM roles where communication skills matter. Let me show you how to write one that doesn't suck.
Does Anyone Actually Read Cover Letters?
First, let's address the elephant: do cover letters even matter?
The honest answer: it depends.
When cover letters matter:
- •Smaller companies where hiring managers review applications personally
- •Roles where written communication is critical (PM qualifies)
- •Competitive roles where you need differentiation
- •Career transitions where you need to explain the "why"
- •Companies that explicitly request them
When they probably don't:
- •Large companies with automated screening
- •When the application doesn't have a cover letter field
- •When the hiring manager has already decided to interview you based on resume/referral
My take: write a good one anyway. The downside of a bad cover letter is low, but the upside of a great one is real.
What Cover Letters Are For
A cover letter should do one thing: make the hiring manager want to interview you.
It's not a summary of your resume. It's not a place to list your skills. It's a persuasive document that answers one question: "Why should I spend 30 minutes talking to this person?"
What it should accomplish:
- •Show you understand the role and company
- •Highlight the most relevant parts of your experience
- •Demonstrate your communication skills (meta, but real)
- •Give personality that doesn't come through on a resume
- •Address anything unusual in your application (transitions, gaps, etc.)
The Structure That Works
Here's a framework that consistently performs well:
Opening: The Hook (2-3 sentences)
Skip "I'm writing to apply for..." Boring. Obvious.
Instead, lead with something that shows you understand the company or role:
When I saw you were looking for a PM to own the checkout experience, I got genuinely excited. I spent the last two years obsessing over e-commerce conversion at [Company], and I have strong opinions about what makes checkout flows succeed or fail.
This shows: I understand the role, I have relevant experience, and I care enough to have opinions.
Middle: Your Relevant Story (2-3 short paragraphs)
This is where you connect your experience to their needs. Don't just list accomplishments—tell a quick story that demonstrates fit.
At [Company], I owned our checkout optimization roadmap. When I took over, our cart abandonment was 68%—above industry average and costing us roughly $2M annually. Over 18 months, through a combination of payment method expansion, trust signal improvements, and flow simplification, we brought that down to 51%.
What I learned: checkout isn't just about removing friction. It's about understanding the specific anxieties your users have at the moment of purchase. For our audience, it was shipping costs and return policies. For yours, I'd want to dig into the data to find the equivalent levers.
This shows: specific relevant experience, quantified impact, and transferable thinking.
Closing: The Ask (2-3 sentences)
End with confidence, not desperation:
I'd love to discuss how my experience with checkout optimization could translate to [Company]. I'm especially curious about how you're thinking about the mobile purchase flow—I have some thoughts I'd be happy to share.
This shows: confidence, specific interest, and you're bringing value (thoughts to share), not just asking for something.
What to Avoid
Generic statements
Bad: "I'm a results-driven product manager with 5+ years of experience passionate about building great products."
This says nothing. Anyone could write it. Delete.
Repeating your resume
Bad: "In my current role, I work with engineers and designers to ship features. Prior to that, I was at Company X where I also worked on products."
They can read your resume. Don't waste cover letter space on information they already have.
Obvious enthusiasm
Bad: "I'm incredibly excited about the opportunity to join [Company]. I've been a huge fan of your product for years."
Everyone claims this. It's not differentiation. Show enthusiasm through specificity, not adjectives.
Wall of text
A cover letter should be 250-350 words maximum. Three to four short paragraphs. White space is your friend.
Being too humble
Bad: "I know I may not have all the experience you're looking for, but I'm a fast learner..."
Don't undercut yourself. If you're qualified, act like it. If you're not, the cover letter won't save you anyway.
A Real-ish Example
Here's a complete cover letter for a hypothetical PM role:
Subject: PM Application - Checkout Experience
Hi [Hiring Manager Name],
I spent the last three years obsessing over why people abandon shopping carts, and I'd love to bring that obsession to [Company].
At [Current Company], I took checkout conversion from 32% to 47%—worth roughly $4M annually—by focusing on the anxieties that arise at purchase moment. Our users worried about returns and shipping costs, so we added clearer policies and implemented a shipping calculator earlier in the flow. Simple changes, but they required digging into session recordings and qualitative research to identify the real blockers.
What I find interesting about [Company]'s challenge is that your users are making higher-consideration purchases. The anxieties are different—probably more about product quality and authenticity than logistics. I'd want to understand your current funnel data and user research before proposing solutions, but I have hypotheses about what might be suppressing conversion that I'd be happy to discuss.
I'm drawn to this role because I want to work on checkout at a company where the purchase decision is genuinely meaningful to customers. That's more interesting to me than optimizing impulse-buy conversion.
Happy to share more about my approach in a conversation.
[Your Name]
~280 words. Shows understanding, demonstrates relevant experience, indicates how you'd approach the role, and has a voice.
Cover Letters for Career Changers
If you're transitioning into PM, your cover letter is critical. It needs to answer: "Why should we take a chance on someone without PM experience?"
Lead with the "why":
After four years as a software engineer, I realized I cared more about what we were building than how we were building it. I kept asking questions about user needs and prioritization—questions that were supposed to be someone else's job. That's when I knew I wanted to be in product.
Connect your experience:
As an engineer, I shipped features that users never adopted, and I shipped features that transformed our metrics. The difference was always whether we understood the real problem. I want to spend my career making sure we understand the problem before we build the solution.
Acknowledge the gap, then move past it:
I know I'm early in my PM career, but I've already done PM work—just without the title. [One or two concrete examples.] I'm looking for a company willing to bet on someone with strong fundamentals and a different perspective.
Final Thoughts
A great cover letter won't overcome a weak resume or wrong-fit experience. But for qualified candidates, it can be the difference between getting an interview and getting lost in the pile.
Write it for the specific role. Show you understand their problems. Demonstrate your communication skills by being clear and concise. Have a voice.
And if you're staring at a blank page, just answer this question: "Why should this company be excited to interview me?"
If you have a good answer to that, you have a good cover letter.
