How newsletter ad revenue is calculated
Newsletter ad revenue is determined by three core inputs: your monthly ad impressions, the eCPM (effective cost per 1,000 impressions) you can command from advertisers, and how many ad slots you run per send.
Monthly ad impressions = Subscribers × Open Rate × Sends per Month × Ad Slots per Send. With MailAdx's open-time ad serving, impressions only count when subscribers actually open your email — not when you send it. This means you never pay for unopened sends, and advertisers get real exposure data.
eCPM benchmarks by niche: General-interest newsletters typically earn $2–$4 eCPM. B2B SaaS, finance, developer, and marketing audiences earn $4–$8 eCPM. High-end finance and professional verticals in the US routinely earn $15–$25+ CPM on direct-sold deals.
Revenue share vs flat fee: Unlike marketplaces that take a percentage of your earnings, MailAdx charges a flat per-impression serving fee (~$0.30–$0.50 per 1,000 impressions). You keep 100% of what advertisers pay you above that fee.
What increases your eCPM
- B2B or high-intent niche (finance, SaaS, legal)
- High open rates (40%+) signal quality to advertisers
- Direct-sold deals negotiated above floor price
- Consistent, engaged audience with low churn
What reduces eCPM
- Very broad or general-interest audience
- Low open rates (<25%) or declining engagement
- Heavy reliance on passive ad network fill only
- No floor price management (underselling inventory)
