Quality Beats Cheap CPL: 4-5x Engagement Lift
The Story
The counterintuitive insight that founded The Feed Media: “Subscribers from higher-cost ads often had 4-5x higher engagement than those from cheaper campaigns” (Source 1).
“He’d been working with newsletters since 2023, and recognized a fundamental disconnect in how other agencies measured success. While most chase the lowest ad cost per subscriber, Nathan discovered” the engagement lift (Source 1).
Nathan’s framing: “We put the money where the best ratio of quality-to-cost exists. There are no free lunches. Can you introduce shitty quality subscribers and still sell those people to advertisers and make a lot of money upfront? Yes. But when you get to a part where you’re declining, it becomes really hard to get out of that hole” (Source 1).
His agency replaced single-metric reporting with a composite: “his team built a measurement system that combines the cost per lead, open rate, and click-through rate for subscribers coming in through any given ad (or in any given segment)” (Source 1).
The result across 18 months: “close to 4 million newsletter subscribers” driven across the client base “by convincing his clients to prioritize quality over cheap growth” (Source 1).
The spend scale where this matters: clients are “spending 50, a hundred, 300, $500,000 a month on newsletters. Profitably” (Source 2).
Two ads with the same CPL but different CTRs (2% vs 6-7%) “are completely different outcomes” — the cheaper-looking ad can be more expensive once sponsor revenue downstream collapses (Source 1).
Lesson for Creators
A single-number metric for ad performance is a trap because it lets the optimization run downstream of the actual business outcome. Cost-per-lead is upstream of sponsor revenue, which is upstream of churn-or-grow — measuring only the upstream metric makes the downstream one quietly decay. Nathan’s fix is structural, not motivational: the dashboard tracks CPL, open, and CTR per ad cohort, so cheap-but-low-engagement ads get caught the week they run, not six months later when sponsors notice. If you can only afford to track one metric, track the one closest to revenue, not the one closest to spend.
