A newsletter media kit that brands can book from
Your audience, stats, placements and prices on one live page with a shareable link. No outdated PDF, no rate-card email: brands read it and book.
What is a newsletter media kit?
A newsletter media kit is a short document or page that tells potential sponsors who your newsletter reaches, how engaged those readers are, which ad placements you offer and how much they cost. It typically covers your subscriber count, open rate, click rate, audience profile, publishing schedule, sponsorship formats and prices.
Most creators build theirs as a PDF or a slide deck, then attach it to pitch emails. The problem is that a PDF goes stale the moment your list grows, can't be booked from, and asks brands to trust numbers you typed yourself. Every interested brand still has to email you to check dates and pay.
LetterBid turns your media kit into a storefront: a public page with your newsletter, audience and sponsorship packs, built from blocks such as a hero, stats, packs, FAQ and testimonials. It has its own shareable link, it updates when you change it, and brands can pick a pack and book without creating an account first.
Everything a sponsor looks for, in one link
Layouts and blocks: Pick a layout and arrange blocks for your hero, stats, packs, FAQ and testimonials. Lead with what makes your audience valuable instead of fighting a slide template.
Audience and engagement: Show your audience size, open rate, topics and who your readers are. Specific beats vague: brands want to know exactly who they'll reach and how often those readers open.
Verified badge: Submit screenshots of your platform dashboard and recent analytics. Once the LetterBid team approves them, your storefront carries a Verified badge brands can trust.
LetterBid verified results: After 3 tracked campaigns, your storefront shows average Filtered clicks, average cost per click and average click rate, measured by LetterBid rather than self-reported.
Rate card that is bookable: Your packs and bundles are listed with their prices: dedicated email, sponsored ad or banner ad. Brands see the exact price they'll pay and can book it directly.
One link, anywhere: Put your storefront link in your newsletter footer, your website, your social bio and every pitch email. Storefront stats show how many views and clicks it gets.
How to build your newsletter media kit on LetterBid
1. Fill in your newsletter profile: Add your newsletter name, description, topics, audience size, open rate and publishing schedule. This is the core of what any sponsor wants to know.
2. Verify your audience: Upload screenshots of your Beehiiv, Substack, Kit or Mailchimp dashboard showing subscribers, recent open and click rates, and where your readers are, to earn the Verified badge.
3. Add packs and design the page: Create packs with your placements and prices, then choose a layout and add blocks: hero, stats, packs, FAQ and testimonials from sponsors you've worked with.
4. Share your link and get booked: Publish and share your storefront link. Brands can book a pack or send a custom offer, and every tracked campaign adds to the results your media kit shows.
Why a live media kit beats a PDF
A media kit's job is to turn a brand's interest into a booking. A static file can only start the conversation. A storefront finishes it: the numbers are current, the proof is verified and the next step is a button, not an email.

Frequently asked questions
What should a newsletter media kit include?
At minimum: what your newsletter is about, your subscriber count, average open and click rates, who your readers are, how often you publish, the sponsorship placements you offer and their prices. Testimonials or results from past sponsors make it much stronger.
Should I put prices in my newsletter media kit?
Showing prices saves both sides time and filters for brands that can afford you. On LetterBid, your packs are listed with prices brands pay exactly, and brands that want something different can still send a custom offer you can accept, decline or counter.
Is a LetterBid storefront the same as a media kit?
It covers the same ground: audience, engagement, placements and prices. The difference is that it is a live page with a shareable link, it can show a Verified badge and LetterBid verified results, and brands can book directly from it.
How do I prove my newsletter stats to sponsors?
Request verification from your profile by sending screenshots of your platform dashboard, your analytics for the last 30 to 90 days, and where your subscribers are. The LetterBid team reviews them, and once approved your storefront shows a Verified badge.
What are LetterBid verified results?
After 3 tracked campaigns, your storefront shows your average Filtered clicks, average cost per click and average click rate. These are measured by LetterBid through the tracking link on each booking, so brands can see results that aren't self-reported.
Can I still send my media kit in pitch emails?
Yes. Paste your storefront link into any pitch, your website or your newsletter footer. Brands that open it can book without creating an account first, confirming their email with a code at the end.
Do I need a large list to have a media kit?
No. Brands care about fit and engagement as much as size, so a small newsletter with a clear niche and strong open rates is worth presenting well. Your storefront is free to create at any list size.
