The ad unit

One sponsor card per free issue, clearly labeled, placed inside the briefing your audience opened on purpose. No banners, no pop-ups, no second slot competing for attention. Premium (paid-subscriber) issues carry no ads at all.

How targeting works

  • Contextual: your ad runs in the verticals you pick (by industry and topic).
  • First-party behavioral: we match against what readers actually click in our own newsletters, nothing else.
  • No third-party data: no cookies, no data brokers, no fingerprinting. We do not even store reader IP addresses.
  • Honest reporting: you get a live report with delivered, viewed (opened), and bot-filtered clicks, methodology stated on the page.
