Questions

Which brands are sponsoring newsletters right now?

In the 7 days from Oct 9 to Oct 15, the most active were Roku, Wispr Flow, Sprinto, Atlassian, Particleformen. The full ranking is on this page, rebuilt every day.

What does "first ad we saw" mean?

Book a Sponsor had never read an ad from that brand before this week. Our reading of newsletters grew in late August 2026, so some of these brands have sponsored newsletters before and are new to us, not new to buying.

Where does this data come from?

Mostly from published issues: Book a Sponsor records a placement when an issue shows it as an ad (a sponsor label, a tracked link or ad copy). The rest come from newsletters' own sponsor pages and booking storefronts, which show past sponsors' logos, and from articles that name a sponsorship. Political and adult newsletters are left out.
