Why price on opens

A sponsor is buying attention, not a raw list size. Opens-based pricing rewards an engaged audience: 3,000 opens on a tight niche list is worth more than 3,000 opens spread across a broad, low-intent one. The niche you pick sets the CPM band, because a reader a finance sponsor wants to reach is worth more than a general one. Once you have the number, you can sanity-check any flat quote a sponsor sends against what the placement is actually worth.

Frequently asked questions

It estimates the opens on one issue (subscribers times your open rate), then applies a CPM range for your niche. CPM is the price per 1,000 opens. A sponsor paying a $30 CPM for 4,000 opens is paying $120 for that send. The result is a low, mid, and high figure so you have room to negotiate.

They are rough industry ranges drawn from public newsletter advertising benchmarks: Paved marketplace data, the beehiiv Ad Network, and shared sponsorship rate cards from Who Sponsors Stuff and Sponsy. They are reviewed each quarter. Your real rate depends on your audience quality, engagement, and how much a sponsor wants your specific readers, so treat the output as a starting point, not a guarantee.

This calculator prices on opens, because that is what a sponsor actually reaches and it rewards an engaged list over a big but quiet one. Some operators quote a flat rate per send instead. Either way, knowing your opens-based CPM tells you whether a flat quote is above or below market.

Higher-intent, higher-budget niches command more. Finance, B2B, SaaS, and marketing newsletters sit at the top of the range; general lifestyle and entertainment sit lower. The niche you pick sets the CPM band the calculator uses.
