# Copywriter Cover Letter: Examples and Structure

> A copywriter cover letter is a writing sample, so it has to be short, clear and sound like you. Open with a line that shows you've studied their work, point to two or three pieces in your portfolio that match the role, and end by asking for a conversation, in under 250 words.

## Key takeaways

- A copywriter cover letter is itself a writing sample, so it has to be short, clear and sound like you.
- The opening line of a copywriter cover letter should show you've studied the company's work.
- A strong copywriter cover letter points to two or three portfolio pieces that match the role.
- Keep a copywriter cover letter under 250 words and end it by asking for a conversation.
- Junior copywriters without published work can use spec pieces, school projects or freelance work as proof.

## What does a copywriter cover letter need to prove?

That you can write. Every other cover letter describes skills; yours demonstrates the one that matters. The hiring manager will judge the letter the way they'd judge a headline: did it make them want to read the next line?

After that, it needs to prove you've looked at their work and that your portfolio has pieces like the ones they need.

## How is a copywriter cover letter different?

The letter itself is part of the portfolio. That changes three things:

- **Voice counts.** Write the way you'd write for a brand with a warm, plain voice, and let your own personality into it. Stiff formal phrasing works against you; a line only you would write works for you.
- **Shorter is better.** Editing is the job. A tight 200-word letter shows more skill than a 400-word one.
- **The portfolio does the proving.** Point to specific pieces, with links, instead of describing your range.

Don't write a gimmick letter, such as one styled as an ad or a press release, unless the posting invites it. Most hiring managers want to see clear writing, not a stunt.

## Structure

Three or four short paragraphs, under 250 words.

1. **Opening:** one line that shows you've read their work, then the role.
2. **Portfolio proof:** two or three pieces that match the posting, with a line on each: the brief and what it did.
3. **How you work:** one short paragraph on how you take a brief, work with an art director or handle feedback.
4. **Close:** ask for a conversation and link the portfolio again.

The examples below are scaffolding. Of all people, a copywriter shouldn't send them as written: rewrite every line in your own voice, because the letter is your first writing sample.

## Example 1: agency copywriter

```text
Dear [Creative director's name],

[One line on a specific piece of their work and why it worked, e.g. the campaign line, the tone of a recent spot]. I'd like to write work like that, so I'm applying for the Copywriter role at [Agency].

Three pieces in my portfolio match what you're looking for:
- [Piece 1]: [the brief in a few words] for [client or brand]. [What it did, e.g. it became the campaign line for the year].
- [Piece 2]: [the brief] for [client]. [Result or what you learned].
- [Piece 3]: [a format from the posting, e.g. social scripts] for [client].

I work best paired with an art director from the first conversation, and I write a lot of bad lines quickly so we can find the good one.

I'd love to talk. My portfolio is at [link].

[Your name]
```

## Example 2: in-house brand or product copywriter

```text
Dear [Hiring manager's name],

I'm applying for the Copywriter role at [Company]. Your [product pages / emails / app copy] already [observation, e.g. sound like a person, which is rare in your category], and I'd like to help keep that true as you [launch, grow or expand, from the posting].

At [Current company], I write [channels, e.g. lifecycle emails, landing pages and in-app messages] for [audience]. A rewrite of our [page or email] [result, e.g. lifted sign-ups by X% in an A/B test], and I maintain the voice guide the rest of the team writes from.

Samples are here: [link], including [the piece most like this role].

I'd welcome a conversation.

Best regards,
[Your name]
```

## Example 3: junior copywriter

```text
Dear [Hiring manager's name],

[One line on their work that you noticed]. I'm applying for the Junior Copywriter role at [Company].

I've just finished [course, portfolio school or degree], where I wrote [spec campaigns or projects]. My favorite is [piece]: [the brief and your idea in one sentence]. I also write [real work, e.g. product descriptions for a local shop], which taught me to write to a word count and a deadline.

I take feedback well and I rewrite without sulking. My portfolio is at [link].

Thank you for reading.

[Your name]
```

## Opening lines to adapt

- "Your [campaign or line] did [specific thing] in [number] words. I'd like to work on the team that wrote it."
- "I've read your last [number] emails, and [observation]."
- "Your posting asks for someone who can write [format]. Here are three I wrote."
- "I'm a copywriter who [your specialism, e.g. writes product pages that convert], applying for [role]."

## Mistakes to avoid

- **Describing yourself as creative.** Show it instead, with one opening line that does the work.
- **No portfolio link, or a link buried at the bottom.** Put it in the body and in the signature.
- **Sending the same letter everywhere.** Write a fresh opening line about their work for each application; it's what gets the rest read.
- **Typos.** In this role, one is often enough to stop the read, so read the letter aloud once before you send it.
- **Taking credit for a team's work.** Say what you wrote. Creative directors will ask in the interview.

## FAQ

### How long should a copywriter cover letter be?

Under 250 words. Your editing is being judged, and a short letter that says something beats a long one.

### Should a copywriter cover letter be creative?

It should be well written and sound like you. A clever format can work for an agency that asks for it, but clear writing with a sharp opening line is the safer choice.

### What if I don't have published work yet?

You can still apply with confidence. Use spec work: rewrite a real brand's homepage or create a campaign for a real product, and say it's spec. Add any paid writing, even small jobs, as proof you can write to a brief.

### Should I attach writing samples or link to them?

Link to a portfolio site or a shared folder, unless the posting asks for attachments. Name the pieces most relevant to this role in the letter so they know where to start.
