One report, one price

€349 one-time

One newsletter, one niche, one report. B2B service; VAT treatment depends on your country and is handled at checkout.

The math: newsletters comparable to our sample sell primary placements at $1,950 and up (CloudSecList's public rate card, sold out into 2026). One closed sponsor at that level covers this report several times over, and four booked slots a month is roughly $8,000 of inventory most niche newsletters leave unmonetized.

Questions, answered plainly

My list is under 5,000 subscribers. Is this for me?

Honest answer: direct sponsorship sales work best for niched B2B or prosumer newsletters from roughly 2,000 engaged subscribers, and get materially easier above 5,000. If your list is general-interest and small, an ad network is probably a better first step, and we would rather tell you that than sell you a report.

How is this different from a sponsor database?

Databases sell you the same list they sell everyone. This report is built for one newsletter: brands matched to your niche with dated evidence they already sponsor your peers, the person likely to own that budget with the source for each claim, and a written pitch per brand. Fixed price, no commission. Marketplaces charge 15 to 30 percent of every deal (Paved lists a 30 percent marketplace fee; Passionfroot up to 15 percent plus transaction fees, per their public pricing pages).

Does this only work for cybersecurity newsletters?

No. The sample is cybersecurity because it was our first vertical, but the method is niche-agnostic. What it does require is a vertical with enough comparable newsletters and podcasts that already carry sponsors, roughly ten or more. That is exactly what the fit check verifies before any work starts, and if your niche does not clear that bar, we tell you and refund in full.

Do you guarantee I will close a sponsor?

No, and you should distrust anyone who does. What we guarantee is the evidence: every brand in your report comes with a dated, linked sponsorship observation you can check yourself, and any email address we could not verify is marked as such.

Where does the data come from?

Public sources only: newsletter archives, podcast feeds, sponsor pages, press releases. Nothing scraped from behind a login, nobody contacted on your behalf, no guessed email addresses.

What do you need from me?

Five minutes: your newsletter URL, your niche in one sentence, subscriber count, open rate if you know it, and optionally the newsletters you consider comparable. The report is delivered within 5 business days as a PDF plus a CSV of contacts.
