Questions

Which brands are sponsoring newsletters right now?

In the 7 days from Sep 25 to Oct 1, the most active were Attio, Atlassian, Incogni, Goodmorningalerts, IM8. The full ranking is on this page, rebuilt every day.

What does "first ad we saw" mean?

Sponsor Radar 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?

Published issues. A placement counts when the issue shows it as an ad: a sponsor label, a tracked link or ad copy. Nothing is self-reported, and political and adult newsletters are left out.

Pitch this week's buyers before they book
