Three entries from the sample report

Subject: You bought 4 newsletters in July. Missing one.

Tines ran the same campaign across Unsupervised Learning, CloudSecList, and tl;dr sec in the last five weeks, so security newsletters clearly perform for you. [Newsletter] is the one you haven't bought: ~15,000 subscribers, almost all detection engineers, SOC leads, and threat intel practitioners. Weekly, 163 issues, zero sponsors to date, clean inventory. Primary placement is $2,000-2,500. For reference, CloudSecList charges $1,950 at 12k subscribers and is sold out into 2026. Worth a 15-minute call, or shall I just send open dates?

Subject: The Soap Box audience, but 100% detection people

The Soap Box episode on threat hunting driving detection (July 8) landed in front of a broad security audience. My readers are the narrow version of that: ~15,000 detection engineers, threat hunters and SOC leads, every week, 163 issues in. Fresh off your Series A, if pipeline from practitioners matters this quarter: the newsletter has carried zero sponsors ever. First brand in gets clean attention. Primary placement is $2,000-2,500. You write on Substack; you know what this inventory is worth. Call?

Subject: You own cyber podcasts. This is the newsletter gap.

ThreatLocker is on every Darknet Diaries episode this quarter, plus Defense in Depth and a full week of Cyber Security Headlines. Your audio coverage is total; your newsletter coverage isn't. [Newsletter]: ~15,000 detection engineers and SOC leads, the hands-on evaluators of endpoint controls, weekly, 163 issues, zero sponsors to date. Primary placement is $2,000-2,500. Reply with a name if someone on demand gen owns this, or I'll send open dates.
