Newsletter media kit: what to include (and what to cut)
A practical media kit checklist for newsletter and podcast creators: the audience facts sponsors ask for, how to present them, and what to leave out.
Key takeaways
- A media kit answers three sponsor questions: who reads this, what do they do after reading, and what does it cost to reach them.
- One to two pages is enough. A short, accurate kit beats a long designed one that nobody reads or updates.
- Include only numbers you can verify, with the date you measured them. Stale or rounded-up figures are the fastest way to lose a sponsor's trust.
- Keep price on a separate rate card so you can update it without redoing the whole kit.

A media kit has a reputation for being a design project. It is not. For a solo creator, it is a short, honest document that lets a sponsor decide quickly whether you are a fit. The kits that work are the ones a sponsor can read in two minutes and trust.
This checklist covers what to put in, what to leave out, and how to keep it from going stale. It pairs with the rate card framework, which deals with price.
What a sponsor is trying to learn
Strip away the design and a sponsor wants to know three things:
- Who is the audience? Not "creators" or "professionals", but specifically who, and why they would care about the sponsor's product.
- Do they pay attention? Open rate, click rate or downloads show whether the audience engages.
- What will it cost, and how do I book? The practical question that decides whether the conversation continues.
Everything in your kit should serve one of those. If it does not, cut it.
The checklist
About the publication
- One-line description: what it covers and for whom
- Format and cadence: weekly newsletter, biweekly podcast, and so on
- How long you have been publishing: a plain fact that signals consistency
Audience
- Size: subscribers for a newsletter, average downloads per episode for a podcast
- Engagement: open rate and click rate, or average downloads in a fixed window
- Who they are: roles, industries, interests, and anything you actually know from surveys or sign-up data
- Measurement date: when you pulled these numbers
The measurement date is the most overlooked line and one of the most valuable. It tells the sponsor the figures are real and recent.
Ad formats
- Each placement you sell (primary, secondary, classified, host-read, and so on) with a short description of where it appears
- Any limits, such as one primary sponsor per issue
- Lead time and asset requirements, so a sponsor knows what to prepare. The asset checklist covers this in detail.
Proof
- Past or current sponsors you have permission to name
- One short result, if you have one and the sponsor is comfortable with it being shared
- A sample issue or episode a sponsor can look at
Never invent testimonials or imply endorsements you do not have. A kit with no logos and honest numbers is stronger than one with borrowed credibility.
How to book
- A named contact and email
- What happens next: reply, receive a rate card, agree a date
- Your typical response time
What to cut
- Subscriber counts without engagement. A big list with a low open rate is a weakness presented as a strength.
- Rounded-up numbers. "Over 10,000" when you have 9,400 will surface when a sponsor checks, and it casts doubt on everything else.
- Walls of demographics you cannot back up. If you do not have data, describe the audience qualitatively and say so.
- Pricing that changes often. Put it on a separate rate card.
- Design flourishes that hide the numbers. Clean beats clever.
One kit, two formats
Keep a short PDF or web page version for sending, and a version in the body of an email for a quick first reply. The email version can be five lines: who you reach, your engagement, your formats and a link to the longer kit. Many first conversations never need more.
Keeping it current
A media kit decays quietly. Set a calendar reminder to refresh the numbers each quarter, and update it after any change to your audience size, send frequency or formats. When you update, change the measurement date even if the numbers barely moved. The date is part of the proof.
From kit to rate card to deal
The kit gets a sponsor interested, the rate card gives them a price and the deal is where the work starts. A free rate-card generator can produce the price page from your audience size, open rate and niche, and worked examples show what the finished result looks like across niches. Once a sponsor says yes, the quality of the operations behind the scenes decides whether they come back, which is the subject of the renewal playbook.
Frequently asked questions
What is a media kit for a newsletter?
A short document that tells a potential sponsor who your audience is, how engaged they are, what ad formats you offer and how to book. It is usually one or two pages and is updated whenever your numbers change.
What should a newsletter media kit include?
A one-line description of the publication, audience size and open or click rates with a measurement date, audience description, available ad formats, a short list of past or current sponsors if you have permission to name them, and a contact for booking.
Should I put prices in my media kit?
Many creators keep prices on a separate rate card and share it when a sponsor expresses interest. That lets you update pricing without reissuing the kit and keeps the first conversation about fit, not cost.
How often should I update my media kit?
Refresh the numbers at least once a quarter and any time your audience changes materially. Always show the date the figures were measured so a sponsor knows how current they are.
