For newsletter operators selling sponsorships · beehiiv · Substack · Kit
Enter your list size, opens, click rate, niche and current pricing. The kit gives you an editable CPM-based worksheet, a media-kit draft, sponsor reply templates and an inventory tracker. It is practical sales-operations education, not a promise that a sponsor will accept any rate.
The free checker is a private planning estimate. No email required; nothing is uploaded by the static tool.
Figures from public 2025 beehiiv & Paved sponsorship-rate data. Your numbers will differ — the tool prices your list, not an average.
The real problem
A sponsor enquiry is hard to answer well if your rate card is a guess. The kit helps you turn subscriber, open, click and niche data into an editable CPM worksheet, then prepare the media-kit and reply assets around that number.
You pick a number that "feels right," then drop it the second a brand says "that's a bit steep" because you have not shown the calculation. The deal closes; the lower anchor is remembered.
A sponsor email lands, you reply within the hour with a number off the top of your head — and that number becomes the anchor they renew against forever. Speed feels professional. It's expensive.
Your list doubled but your rate didn't. Asking feels awkward, so you leave thousands a year on the table — quietly, every single send.
No agreed placement, date, copy deadline or payment terms, then everyone is trying to reconstruct the deal after the issue has gone out.
The fix is a documented workflow: know your defensible estimate before you reply, having the words to hold it when they push back, and a simple terms worksheet for agreed details. That's what this is, and you can check the first part, free, in the next 60 seconds.
How it works
Enter five numbers from your dashboard. The Rate-Card Engine prices every placement on CPM — cost per 1,000 opens — using your niche's 2025 benchmark band. Now you have a number you can defend with maths, not a guess.
The tool auto-fills a clean one-page media kit from your numbers and rate card. Print to PDF. Done. (And if you have no sponsors yet, it swaps in a "what a partnership looks like" block instead of faking logos.)
Use the outbound sequences to approach relevant brands, the objection scripts to explain your pricing, the rate-review playbook to update it, and the insertion-order draft to record agreed terms.

Questions
Because the calculator was never your problem. A number on its own doesn't fill slots — the words, the outreach, and the nerve to hold your rate do. The free tools give you a number and stop; this gives you the system that turns that number into booked revenue. (You also get a better tool — one that shows its working and builds your media kit.)
Yes. It's platform-agnostic — beehiiv, Substack, Kit/ConvertKit, Ghost, anything that gives you subscribers, open rate and click rate. The benchmark bands cover B2B finance, B2B SaaS/tech, professional, high-intent consumer, and general-interest niches. It's built for engaged lists roughly 2k–100k, but the maths scales either way.
Completely. The tool runs 100% in your browser using JavaScript. Nothing you type — no metrics, no media-kit content — is ever uploaded, stored, or transmitted. Close the tab and it's gone. There's no account and no login.
They're derived from public 2025 newsletter-sponsorship rate data (beehiiv and Paved industry reports), documented in a CSV so you can check exactly what's encoded. They're opening guidance, not a market-price promise. Your niche, engagement quality and reputation move the real number.
An instant download: the browser-based Rate-Card Engine & Media-Kit Generator (an HTML file you open locally), the full GUIDE, the negotiation scripts, the email sequences, the insertion-order and inventory templates, and the benchmark data CSV. No subscription. Yours to keep.
No. It's practical sales and operations guidance plus templates — not legal, financial, tax or advertising-regulatory advice. The insertion order is a plain-English starting point; for larger or unusual deals, have a qualified adviser review your standard terms. You and your sponsors are responsible for clearly labelling sponsored content.
