Where this comes from
Across the whole list, most placements are read from published issues: Book a Sponsor records an ad when an issue shows it as one (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. Our reading grew in late August 2026, so the first date on this page is the first ad we saw, which can be later than harmonic.security's first ever. Rebuilt Oct 3, 2026.
