Most newsletter operators are pricing their inventory wrong — and most advertisers are buying it wrong.

In this episode, Jeff Eisenberg, co-founder of Media Intercept, breaks down how newsletter monetization actually works: why list size and open rate are vanity metrics, the real trade-offs between CPM, CPC, and CPA, and why treating newsletters as a pure bottom-of-funnel performance channel sets everyone up to be disappointed.

Jeff and Chris met at a newsletter conference where — surprisingly — almost nobody was talking about monetization. So they fixed that here.

From bot and VPN traffic to dedicated-send fatigue, AI ad copy, and the case for industry-wide metric standardization, this is a working operator's guide to making your audience monetizable, not just big.

Matt Paulson, founder & CEO of MarketBeat, is just deleted 3 million "active" subscribers from his list — and he's doing it on purpose.

In this episode of Audience Bridge Insights, recorded at MarketBeat's brand new Sioux Falls studio, I sit down with Matt for round two (he was my very first guest on this show) to unpack what's actually happening inside one of financial publishing's biggest email operations in 2026.

We get into the engagement-only future of email, the 5-minute pixel rule that reclassified half their "opens" as automated, why MarketBeat now runs four parallel Beehiiv lists, the "Make Money Button" automation that Matt McGarry credits to Matt, ASN-level bot filtering, and the one metric Matt thinks every newsletter publisher should be obsessing over right now.

If you publish a newsletter — especially in finance, health, or any vertical ISPs treat as "high risk" — this one is required listening.
