The letter, part by part
Callum Lawrence (Copywriter, In-House Marketing Team) is applying to be a Senior Copywriter at Pinebrook Creative Agency. Here is what each paragraph does.
- The hook
- The proof
- The fit
- The close
Dear Mr. Delaney,
Six words on a billboard along I-25 made me pull into a coffee shop and look up Pinebrook Creative: "Your mountain called. We answered." I have been writing toward lines like that for five years, and the chance to do it as a Senior Copywriter at your agency is one I could not pass up.
Currently I write for the in-house team at Alpine Credit Union, where I cover everything from TV spots to app notifications. My rewrite of our checking account landing page raised sign-ups by 26% in one quarter. I also wrote a direct mail series for first-time homebuyers that achieved a 4.2% response rate, nearly double our previous benchmark, and generated over $3 million in new mortgage applications.
Agency copywriters have to switch voices quickly, and I thrive on that. In a single week I might write playful social captions, plain-language compliance copy, and a 30-second radio script. I partner closely with art directors on concepts, test headlines through A/B experiments, and use clear creative briefs to keep reviews short. Strong storytelling and disciplined editing are the two skills I rely on most.
I have included a link to my portfolio and would be glad to take on a short spec assignment. I would value the opportunity to talk with you about Pinebrook's upcoming campaigns and how my work could strengthen them for your clients. Thank you for your time and consideration.
Best regards,
Callum Lawrence
Skills to mention
Employers hiring a copywriter often look for these. Name the ones you really have, with an example.
Phrases you can borrow
Change the details to your own, then copy them into your letter.
I write copy that earns attention in a crowded feed and then gives readers a reason to act.
I can move from a playful brand voice to precise regulated language without missing a beat.
I test headlines relentlessly, because the best idea in the room is the one the data supports.
I treat every brief as a puzzle about what the reader needs to hear right now.
Tips for a copywriter cover letter
- Make your first line as strong as a headline; a copywriter's opening is their first test.
- Show results like conversion rates, click-throughs, or response rates for copy you wrote.
- Demonstrate range by mentioning different formats, from social posts to long-form landing pages.
- Mention how you collaborate with designers and art directors on concepts.
- Keep sentences short and punchy, cutting any word that does not earn its place.
Mistakes to avoid
- Opening with a cliché, which suggests your ads will be forgettable too.
- Describing yourself as creative without proving it through results or examples.
- Writing long, padded paragraphs that ignore the brevity copywriters are hired for.
