Cover letter examples that actually work (and how to write yours)

Theory is useful, but examples make it concrete. This page has real cover letters for different situations — with analysis of what works in each one. Use them as a starting point, not a template to copy.

Example 1: Mid-level developer applying to a startup

Subject: Frontend Developer Application — [Startup Name]

Hi [Recruiter's name],

When I read that [Startup] is building the next generation of collaboration tools for remote teams, I immediately recognised this as the product I use myself and wished had existed when I started working fully remote.

Over the past 3 years as a Frontend Developer at [Current Company], I've built and maintained interfaces serving 50,000 daily users — using React, TypeScript and GraphQL. The project I'm most proud of was the redesign of the main dashboard, which reduced load time by 62% and increased monthly retention by 18 percentage points.

What specifically attracts me to [Startup] is your "design-first development" approach I saw on your engineering blog. It's exactly how I think software should be built, and it's rare to find teams that genuinely practise it.

I'm available for a quick call whenever works best for you — I'd love to learn more about the technical challenges the team is facing.

Best,
[Name]

What works: Genuine personal hook, concrete metrics (50k users, 62% improvement, +18pp retention), specific reference to company content (engineering blog), direct call-to-action without servility.

Example 2: Marketing professional transitioning to product

Hi [Name],

I've spent the last 4 years in marketing trying to understand why users behave in certain ways — and working alongside product managers who had the answers I wanted to have. I'm now making the transition into product, and [Company] is where I want to do it.

As Marketing Manager at [Current Company], I led 3 end-to-end product launches — from market research to post-launch campaign — managing £200k budgets and coordinating teams of 8. I learnt to read user behaviour data, build personas and articulate value propositions that convert. I'm cementing this transition with the Pragmatic Institute Product Management certification.

The specific reason I'm applying to [Company] is your product-led growth model — it's the approach that fascinates me most, and one where my marketing background creates a genuine differentiator.

I can share case studies from projects where I touched both marketing and product if that's helpful.
[Name]

What works: Honest transition narrative that explains the "why", specific skill transfer with numbers, certification that demonstrates commitment, concrete reason for that specific company.

Example 3: Recent graduate applying for first internship

Hi [Name],

In my dissertation project in Data Science, I used machine learning to predict hotel booking cancellations with 87% accuracy — and the model ended up being used by the hotel that gave us the data. That moment — seeing code solve a real problem — is what brought me to apply for the [Internship Programme] at [Company].

Throughout my Data Engineering degree at [University], I developed skills in Python, SQL and data visualisation (Power BI, Tableau) in both academic settings and a 15h/week part-time role in analytics. My 2:1 degree shows I can manage multiple commitments effectively.

I don't have formal professional experience — but I have real projects, full availability and a genuine drive to learn from a data team as strong as yours.
[Name]

What works: Opens with a concrete result (87% accuracy, real-world impact), contextualises with training and part-time work, honestly acknowledges lack of experience without apologising — and compensates with energy and projects.

What all effective cover letters have in common

1. Specificity — Numbers, names, details. Vague = forgettable
2. Your own voice — Sounds like a real person, not a template
3. Genuine connection to the company — Shows you did real research
4. Brevity — Under one page. If you can't fit it, cut it
5. Clear call-to-action — Close with a concrete next step
