What is your sponsorship slot worth?

An estimate range built from public benchmarks (listed below), not a promise. Direct deals vary with engagement, niche depth, and how well you pitch. If your open rate beats your peers', charge for it.

Estimated range per placement

$450 – $1,600

How this is calculated

Base rate per 1,000 subscribers per placement, by audience type, taken from public benchmarks: general interest $15-35 (beehiiv's published cost guide), prosumer $25-60, specialized B2B $45-160. The B2B bounds are two real, public rate cards: VuTrinh (data engineering, $450 per slot at ~10,000 subscribers, public media kit) at the low end, CloudSecList (cloud security, $1,950 per placement at 12,000+ subscribers, sold out into 2026) at the high end. Secondary placements are priced at roughly 45 percent of primary and dedicated sends at 160 percent, matching the two-tier packaging observed across the segment. The open-rate adjustment is centered on 42 percent, the midpoint of rates published by niche operators (37 to 50 percent).

Knowing your price is half the job

The other half is knowing which brands are already paying for placements like yours, and who to write to. That is what the Sponsor Folder report does: 30 matched brands with dated evidence, contacts, and ready-to-send pitches.
