# Media Planner Cover Letter: Examples for Agency Roles

> A media planner cover letter should show that you can turn a client's goal into a plan and explain why the money goes where it does. Open with something specific about the agency or its clients, describe one or two plans with the goal, the channels, your part and the result, mention the tools you use, and keep it under about 250 words.

## Key takeaways

- A media planner cover letter should show that you can turn a goal into a plan and explain why the budget goes where it does.
- Describe one or two plans by the goal, the channels, your role, the scope and the result.
- Agency media planner letters should show client work, research and presenting plans, while in-house letters should show business results and managing agency partners.
- Assistant media planner letters can lean on flowcharts, research, reconciliation and any campaign you've run yourself.
- Keep a media planner cover letter under about 250 words and match its wording to the channels in the posting.

## What does a media planner cover letter need to prove?

That you understand the job behind the job: a client has a goal and a budget, and the planner decides which channels, audiences and timing will get there, then explains that choice in a way the client can approve. Your resume lists the plans; the letter shows how you think about them.

If you're weighing the role, the [media planner](/career-guides/media-planner/) guide explains the work, and [media buyer](/career-guides/media-buyer/) explains the team you'll hand plans to.

## Structure

Three or four short paragraphs, under 250 words. The [how to write a cover letter](/cover-letters/how-to-write-a-cover-letter/) guide covers format and length.

1. **Opening:** something specific about the agency, its clients or its recent work, then the role.
2. **One or two plans:** the goal, the channels, your part, the scope and the result.
3. **How you work:** research and tools, working with buyers, strategy and account teams, presenting to clients.
4. **Close:** ask for a conversation.

The examples below are a starting point. Put them in your own words and keep the details that only you would mention, like the test that changed a client's mix; a hiring manager wants to hear how you think, not a template.

## Example 1: agency media planner

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

[Agency]'s work for [client or category, e.g. its retail clients] stood out to me because [specific reason, e.g. how much of it is built around local reach and timing]. I'm applying for the Media Planner role because that's the kind of planning I enjoy most.

At [current agency], I plan [channels] for [X] clients in [categories]. Last year I built the launch plan for [client description, e.g. a regional grocery chain's new delivery service]: the goal was [goal], so I [key decision, e.g. weighted the budget toward connected TV and local social in the 12 launch markets]. The plan [result, e.g. reached X% of the target audience at a CPM below the plan].

I build plans from audience research in [tools], work closely with our buying team on pacing and optimization, and present quarterly reviews to clients.

I'd welcome a conversation about the role.

## Example 2: in-house media planner

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

I'm applying for the Media Planner role at [Company]. [One line on the brand: a campaign, a product launch or how it shows up across channels.]

At [current company], I plan a $[X] annual budget across [channels] and manage our agency partners' plans. Two results I'm proud of:
- [Result 1, e.g. moved X% of spend from linear TV to connected TV and social after a geo test, with no drop in brand search]
- [Result 2, e.g. built the measurement plan that the team now uses for every launch]

I'm comfortable translating media results into business terms for finance and leadership, and I like working with creative and brand teams early, before the plan is set.

I'd be glad to talk about how I could help your team.

## Example 3: assistant or associate media planner

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

I'm applying for the Assistant Media Planner role at [Agency]. [One line on why this agency: its clients, its training program, its work.]

In my [internship / current role] at [company], I [built flowcharts / pulled audience research / reconciled plans against invoices] for [X] clients, and I learned how a plan moves from brief to launch. I also ran [a small paid social campaign for a student organization or local business], where I [what you did and what happened].

I'm organized, comfortable with spreadsheets and eager to learn the planning tools your team uses.

Thank you for considering my application.

## Agency vs in-house: what to emphasize

| | Agency letter | In-house letter |
|---|---|---|
| Lead with | Client plans across categories and channels | Results for one brand and budget |
| Mention | Research, presenting plans, working with buyers, pitches | Business outcomes, measurement, managing agencies |
| Proof | Plans delivered, clients retained, pitches supported | Efficiency gains, tests, results leadership saw |

## Tips

- **Describe clients by category if you can't name them.** "A national quick-service restaurant brand" is enough.
- **Show a decision, not only a task.** "Built the flowchart" is a task; "shifted budget to connected TV after a test" is a decision.
- **Use the posting's channel names.** If it says "programmatic" and "paid social", use those words where they're true.
- **Keep numbers honest.** Use the figures you can explain in an interview, and leave a [placeholder] while you check the rest.

Pair the letter with a [media planner resume](/career-guides/media-planner-resume/) that shows the same plans in bullet form. Recon drafts a cover letter from your resume and the posting, and leaves [placeholders] rather than inventing results.

## FAQ

### How long should a media planner cover letter be?

Under about 250 words. Agencies read a lot of applications, and a short letter with one clear plan story is more likely to be read in full.

### What if I don't have media planning experience yet?

Show the skills behind the job: research, spreadsheets, a campaign you ran yourself, an internship, or coursework on media. The [how to get into advertising](/career-guides/how-to-get-into-advertising/) guide covers entry-level routes.

### Should I mention the tools I use?

Yes, briefly, especially the ones the posting names. Save the full list for the resume.
