Marketing manager cover letter built on campaign results
Marketing leaders reading your letter will judge it like a campaign: does it grab attention, speak to the audience and show results? This prompt has your todo.is agent study the company’s marketing (site, ads, social, blog) and write a letter that leads with the numbers you moved and one idea for their channels.
The prompt
- Write a cover letter for [JOB TITLE] at [COMPANY]. Here is the job ad: [JOB POSTING LINK], and my resume: [ATTACH OR PASTE YOUR RESUME]. My best campaign or program: [CHANNEL, BUDGET, WHAT YOU DID, RESULT]. Look at the company’s website, blog and public social profiles to see which channels they use and where there may be a gap. Say if the role is B2B or B2C and use the right metrics (pipeline, CAC, ROAS, retention). Include one idea for them in a single sentence. Under 330 words, with a strong first line. Give me a Word file and plain text.
What to change
- [JOB TITLE]: e.g. "Marketing Manager", "Growth Marketing Manager", "Brand Manager".
- [COMPANY]: The company name.
- [JOB POSTING LINK]: The job ad link, or paste the text.
- [ATTACH OR PASTE YOUR RESUME]: Your resume file or text.
- [CHANNEL, BUDGET, WHAT YOU DID, RESULT]: e.g. "Paid social for a DTC skincare brand, $40k/month, new creative testing, ROAS 1.8 to 3.1".

- Dear Hiring Team at Petal & Pine,
- Your Instagram is full of customers showing off their plants, but your newsletter has not used one of those photos yet. That is the first thing I would want to test as your Marketing Manager.
- For the last three years I have run growth at Fernly, a direct-to-consumer home goods brand. I manage a £40,000 monthly paid social budget and a team of two. When our return on ad spend stalled at 1.8, I set up a weekly creative test using customer videos instead of studio shots. Within four months ROAS reached 3.1, and cost per first order fell by 35%.
- I also rebuilt our email program in Klaviyo. A welcome series, a post-purchase care guide and a simple win-back flow lifted repeat purchase rate from 21% to 29% in a year. I think about acquisition and retention as one system, which seems to fit your ad’s focus on lifetime value.
- I enjoy working with founders and small teams. I write my own briefs, read the numbers myself every Monday, and explain results in plain words to people outside marketing.
- I would love to talk about how customer content could work across Petal & Pine’s paid and email channels. Thank you for your time.
- All the best,
- Chloe Martin
- Why it works
- • The first line is a specific, kind observation about their channels
- • B2C metrics (ROAS, repeat purchase rate) instead of vague "engagement"
- • Shows both acquisition and retention, matching the ad
- • Budget and team size show the level she works at
How to do it with todo.is
- Copy the prompt and replace the [brackets] with the role and your best campaign.
- Paste it into todo.is (Today screen) or send it to your agent on WhatsApp or Telegram.
- Your agent reviews the company’s marketing channels and writes a letter with one idea for them.
- Edit the idea if you know their market better, then ask for a PDF if the form needs one.
Tips for a better result
- Use the right metrics for the business: pipeline and CAC for B2B, ROAS, AOV and retention for B2C.
- Always mention budget and team size. "Marketing manager" can mean anything from a solo role to a team of twenty.
- Treat the opening line like an ad headline. If it could fit any company, rewrite it.
- Link your portfolio or a case study. Marketing hiring managers like to see the actual work.
marketing manager cover letter: FAQ
- What should a marketing manager cover letter include? Your best campaign with budget and results, the channels you manage, the size of team you lead, and a sign that you understand the company’s audience. One specific idea for them is a strong touch.
- How long should a marketing cover letter be? About 250 to 350 words. A tight letter shows you can write clear copy, which is part of the job.
- Can I use a creative format? For brand or creative roles, a little personality helps. Keep the structure simple so it still reads well in an application system.
- Can my agent check the company’s social media? It can read public pages and profiles in a browser. It does not log in or post anything for you.
