FAQ
How do I price a newsletter sponsorship?+
Start from opens, not subscribers: multiply your subscribers by your open rate to get opens per send, then multiply by your category CPM and divide by 1,000. This calculator does that and benchmarks the CPM against real newsletters in the index.
Should I charge a flat fee or a CPM?+
Most operators quote a flat fee per placement, but CPM is how advertisers compare you to alternatives. Set your flat fee so the implied CPM lands in your category's benchmark range, then adjust for niche quality and demand.
