Copywriter cover letter with a headline worth reading
Agencies and brands judge a copywriter by the first line of the cover letter. This prompt has your todo.is agent read the job ad and the brand’s website, then write a letter with a strong hook, results like conversion lifts, and a clear link to your portfolio.
The prompt
- Write a cover letter for the [JOB TITLE] role at [COMPANY NAME]. Job ad: [JOB POSTING LINK]. My experience: [PASTE YOUR RESUME OR WINS]. Portfolio: [PORTFOLIO LINK]. Read their homepage and one landing page, and open the letter with a short hook that shows I understand their customer. Include 2 results with numbers (conversion rate, CTR, open rate, sales), the formats I write (ads, landing pages, email, UX copy), and a confident close. Max 280 words. Also give me 3 alternative opening lines. Word file plus plain text.
What to change
- [JOB TITLE]: e.g. "Senior Copywriter", "Conversion Copywriter", "Junior Copywriter".
- [COMPANY NAME]: The agency or brand. Your agent reads its website.
- [JOB POSTING LINK]: Link to the ad, or paste the text.
- [PASTE YOUR RESUME OR WINS]: Resume text or attach the file. Short bullets with results are perfect.
- [PORTFOLIO LINK]: Your portfolio site, Behance, or a shared folder of samples.

- Dear Brightloop Studio,
- Your clients sell sleep, not mattresses. I noticed that on the Restwell landing page you built, and it is exactly how I like to write.
- I am a conversion copywriter with five years in DTC and SaaS. Two results I am proud of:
- • Rewrote the pricing page for a meal-kit brand. Trial sign-ups rose 27% in an A/B test over six weeks.
- • Wrote a 5-email welcome series for a skincare shop that now earns about a fifth of its email revenue.
- I write across formats: Meta and Google ads, landing pages, product pages, email flows and in-app microcopy. I start every project with customer research (reviews, support tickets, short interviews), so the words come from the buyer, not the brand.
- Your ad asks for someone who can present ideas to clients. At my current agency I pitch concepts directly to founders and turn their feedback into a second round within 48 hours.
- You will find ads, landing pages and before-and-after rewrites at inesduarte.co/work. I would love to write the next headline your clients remember.
- Best,
- Ines Duarte
- 3 alternative opening lines
- • "Most mattress ads talk about foam. Your work talks about mornings. I want in."
- • "I have one question I ask every brand: what does your customer say at 2 a.m.? Brightloop seems to ask it too."
- • "I write the words that make people click Buy, and I can show you the A/B tests to prove it."
- Why this works
- • Short hook that shows taste, not a summary of the resume
- • Hard numbers from tests, the language of conversion work
- • Under 280 words: brevity is part of the job
How to do it with todo.is
- Copy the prompt and fill in the [brackets], including your portfolio link.
- Paste it on the Today screen in todo.is, or send it to your agent on WhatsApp.
- Your agent reads the brand’s site, writes the letter and three extra openers, and gives you a .docx file.
- Pick the opener you like best and reply "use opener 2" to get the final version.
Tips for a better result
- The opening line is your audition. Test two or three versions before you send.
- Quote results from tests where you can (A/B, before and after). They are more convincing than "improved engagement".
- For agency jobs, show range: one ad, one long page, one email.
- Keep the letter short. A long letter tells a copy chief you cannot edit yourself.
copywriter cover letter: FAQ
- Should a copywriter cover letter be creative? A little. A sharp hook helps, but keep the rest clear and professional. Gimmicks like writing the letter as an ad can backfire unless the agency is known for it.
- What results should a copywriter mention? Conversion rate, click-through rate, email open or click rate, revenue from a campaign, or test wins. If you have no numbers, describe the brief and what the client did next.
- How long should a copywriter cover letter be? Under 300 words. Shorter is better, as long as it includes your best result and a portfolio link.
- Can I use the same letter for many agencies? Change at least the opening and one paragraph for each one. With todo.is, send a new job link and your agent rewrites it from your saved details.
