Ms. Dorotea Ilic Creative Director Wrenfield Outfitters Portland, United States
Application for Senior Copywriter, Lifecycle, Wrenfield Outfitters
Dear Ms. Ilic,
I am applying for the Senior Copywriter, Lifecycle post at Wrenfield Outfitters. I write direct response email, paid search and landing pages, and I have spent the last several years doing it for retail and subscription brands at an agency. My portfolio is at tomikonakashima.example.com and the lifecycle work is the first section.
The piece of work closest to what you are hiring for is a paid search account I inherited at a $54 cost per acquisition. I rebuilt the ad copy around one objection per ad group rather than one benefit per ad group, killed the variants that were winning clicks but not carts, and took it to $31 over eight months. In the same period I rewrote a subscription client's six-email welcome series and click-through moved from 2.1% to 4.4% across 90,000 sends. Neither of those was a clever line. Both came from reading what customers were actually worried about and answering it in the subject line.
I have read your post-purchase emails and your returns page. The returns page does the harder job well, and the emails are not yet using it: the guarantee that resolves the objection lives three clicks away from the moment a customer is worried about it. That is the first thing I would test. I also write inside constraints without arguing about them, having carried a financial services account through compliance review for two years and cut the average number of legal rounds per campaign from three to one.
I am available for a portfolio walkthrough any afternoon this month and can start within four weeks. Thank you for reading.
Sincerely, Tomiko Nakashima
Summary
A copywriter cover letter is the only writing sample a hiring manager is certain to read, so it has to do two jobs at once: prove the voice and prove the commercial result. This guide gives you a full adaptable letter, the openings that work, what to say when nothing was tested, and how to point at the portfolio without repeating it.
Copywriter cover letter examples by experience level
In short, a copywriter cover letter is a one page letter that names the channels you write, gives one commercial result with a number attached, and sends the reader to your portfolio.
It is also the only piece of writing a hiring manager will definitely read. Managers skim the portfolio and scan the resume, but they read the letter, which means they judge it as copy while it argues for you. That is uncomfortable, and it is the opportunity.
Guide to a copywriter cover letter
To help, this guide and the corresponding copywriter cover letter example will cover:
- First, how to structure the letter, paragraph by paragraph
- Next, why the channel and the number belong in the first two sentences
- What to write when nobody tested the work
- Then, how to reference the portfolio without retyping it
- Finally, the openings that make a reader put a strong file aside
How to write a copywriter cover letter
| Paragraph | Its job | Length |
|---|---|---|
| Opening | The role, the channels you write, and the portfolio link | 2 to 3 sentences |
| Evidence | One brief, one channel, one number, one period of time | 4 to 5 sentences |
| Fit | Something accurate about their product or program, and what you would do first | 3 to 4 sentences |
| Close | Availability, the portfolio link again if it is short, thank you | 2 sentences |
The letter is a writing sample, so write it in the voice you are selling
Copywriters lose this job on the letter more often than on the work. The pattern is always the same: a portfolio full of sharp, specific, confident copy attached to a letter that reads like a template from a careers site.
A creative director reading "I am writing to express my keen interest in the Senior Copywriter position" has just been told that you write like that when nobody briefs you.
Write the letter the way you would write a landing page. One idea per paragraph. Short sentences that carry weight. A claim, then the evidence for it. No throat-clearing before the first real fact.
That does not mean gimmicks. A letter that opens with a joke or a fake headline is a different failure. The voice you want is the one you use for a client who is smart and short of time.

What counts as evidence when nobody ran a test
Of course, plenty of good copywriting ships without a test attached. In-house teams at small brands rarely have the traffic to test properly, and agencies often hand off before the numbers come back. Say what is true instead of inventing a percentage.
| Kind of evidence | What it looks like in a sentence |
|---|---|
| Scale | Wrote product copy for 640 SKUs across two catalog rebuilds |
| Voice | Wrote the 14-page voice guide five in-house writers and nine freelancers work from |
| Speed under constraint | Turned around 40 paid social variants a month against a weekly briefing cycle |
| Review | Cut average legal review rounds per campaign from three to one |
| Range | Carried three concurrent accounts in retail, subscription fitness and financial services |
| Reach | Wrote the launch campaign that ran across email, paid social and out of home in nine markets |
| Craft with receipts | Rewrote the pricing page around the three objections support logged most often |
In each case, a hiring manager can test that fact in conversation. By contrast, a made-up lift figure is a fact they can catch.
The portfolio and the letter: how they divide the work
Give the portfolio URL in plain text in the first paragraph and again at the close. Tell the reader which section to open first and why it matches the role. Pick one piece from the portfolio and give the part the portfolio cannot: what the brief actually asked for, what you were not allowed to say, and what happened. Name one accurate thing about their own copy, taken from their site, not from their press coverage.
Do not summarize your whole portfolio in the letter; the letter's job is to make one click worth making. Do not attach a 20MB PDF of work to an application email. Do not rewrite their homepage headline unasked as a demonstration of initiative, which reads as a critique to the person who wrote it. Do not send the letter without checking that the portfolio link opens in a private browser window with no password prompt.
Most of this occupation is self-employed, so the letter is competing with a wide pool
Self-employed workers make up 65 percent of employment for writers and authors, the occupation copywriting is classified within, ahead of professional, scientific and technical services at 9 percent and information at 8 percent (BLS Occupational Outlook Handbook, 2025).
The occupation is projected to change by 0 percent between 2025 and 2035, a decline of about 500 jobs, while still producing roughly 11,900 openings a year, nearly all of them replacements (BLS, 2025 to 2035 projections, published 27 August 2026).
A salaried copywriting post is therefore a replacement seat drawing applications from a large freelance population as well as from other staff writers. That is the reason the letter has to carry a commercial fact early. Everyone in the pile can write a sentence. Far fewer can say what one of their sentences was worth.
Length, format and sending it
One page, four paragraphs, 250 to 400 words. PDF unless the application form says otherwise, named for yourself and the role: tomiko-nakashima-senior-copywriter-cover-letter.pdf.
Address a person. In advertising the creative director, content lead or talent partner is usually findable in a few minutes, and a letter addressed to a team on a file that is otherwise precise undercuts the precision.
If the application is a single text box, keep the structure and drop the formal address block. Also, check that no stray line breaks survived the paste.
Use the same figures your resume uses so the two documents agree. Our copywriter resume example is written with the numbers used here.
Key takeaways
- To start, name the channels you write in the first two sentences, not your enthusiasm.
- Then put the portfolio URL in plain text early, and say which section to open.
- In addition, give one brief, one channel, one number and the period it covers.
- Say what you could not say, because constraints are half of commercial writing.
- Similarly, name one accurate observation about their own copy, taken from their site.
- Write the letter in the voice you are selling, because it is the sample they actually read.
- In short, one page, four paragraphs, addressed to a named person.

Copywriter cover letter questions, answered
How long should a copywriter cover letter be?
One page, four paragraphs, 250 to 400 words. Shorter is fine if every sentence is doing work. The failure mode in this field is not brevity, it is a long letter that restates the resume and never gets to a number.
Should the cover letter be creative?
It should be well written, which is not the same thing. A letter that opens with a fake headline, a mock press release or a joke about the job title is a gamble that mostly loses, because the reader cannot tell yet whether you can do the boring parts. Write it clean, specific and confident, and let the portfolio carry the range.
What if I have no commercial results at all?
Give scale, constraint and range instead. Number of SKUs, size of the voice guide, turnaround under a weekly briefing cycle, review rounds, markets the campaign ran in. Then say what you would measure in the role you are applying for, which shows you think commercially even if nobody has let you prove it yet.
Do I mention freelance work in a letter for a salaried job?
Yes, as a business rather than a gap. Say how many clients you carried at once, in which categories, and what the work produced. Most of the occupation works this way: 65 percent of writers and authors are self-employed (BLS Occupational Outlook Handbook, 2025), so a hiring manager is used to reading it and will only be put off if you sound apologetic about it.
Should I rewrite something of theirs to prove I can do the job?
Only if they asked. Unsolicited rewrites land badly more often than they land well, because the copy you are improving was probably written by the person reading your letter, under constraints you cannot see. One accurate observation about their copy, stated without contempt and followed by what you would test, does the same work and does not insult anyone.
