How do you use the sponsor finder?
Five steps, and the first two are free.
- Paste your link. Put your newsletter, podcast or YouTube channel in the box on the home page. Done when your list starts building, which takes about a minute.
- Read the list. Each row is a brand, where it advertised and the date it was last seen. The buyer sits with the top brands, and contacts for the rest unlock when sending starts. Done when you can name five brands you would run.
- Read the drafted pitches. The pitches are written for your audience. Done when you have noted any brand you already talk to, so you can block it on your dash.
- Start the outreach. A plan from $19 a month after the first 200 emails, which come with a $1 card check. Done when the first emails go out.
- Answer the yeses. Replies land in your inbox, and you close the deal. Done when a brand has a date and a price.
What does a run look like?
The example on our home page, read 6 November 2026: for growthdives.com, 256 brands sponsored business or adjacent newsletters in the last 90 days, and 226 of them (88%) have a buyer we can email. It was built in 10 seconds. Behind every run is the same read: 8,550 brands seen sponsoring 4,988 newsletters, rebuilt daily, mostly from published issues, plus the podcast and YouTube sponsor reads. Data through 10 November 2026.
What are the limits?
- The pitches are cold email, so most brands won't answer, and each reply still needs you to close the deal. Each plan includes a set number of emails a month (Starter $19 a month for up to 600 emails a month, Kit $49 a month for up to 1,500 emails a month, Growth $99 a month for up to 3,000 emails a month), and sending stops at the plan's emails. It collects no payments.
- A run shows brands that bought before, so it can't promise a brand will buy from you. The guarantee is on a reply: first sponsor reply inside 30 days or your money back.
- The first emails come from our mailboxes and domains, not yours.
- Nothing is sent until you start the outreach and pass the card check.

Questions
Is the sponsor finder free?
Yes. The run is free: paste your newsletter, podcast or YouTube channel and see the brands, with the buyer at the top brands and the drafted pitches. The card only comes in when you start the outreach. Book a Sponsor takes a $1 card check for the first 200 emails, then a plan from $19 a month.
Which channels does it work for?
Newsletters, podcasts and YouTube channels. Paste a newsletter address, an Apple Podcasts, Spotify or RSS link, or a YouTube channel link.
Can I see the buyer's email address?
You see a masked address. Book a Sponsor finds and verifies the contact before each pitch and sends from its own mailboxes, and the replies come to you.
What does it not do?
It stops at the yes: you answer the brand, agree the deal and invoice it. It takes no commission, doesn't take calls for you, and it won't work for adult content, which is denied everywhere. The guarantee: first sponsor reply inside 30 days or your money back.
