Which one costs less?

For scale: newsletters with 5,000 to 19,999 subscribers list one main slot at a median $300 (121 newsletters, read 11 November 2026 by Book a Sponsor). SponsorGap's managed plan takes a 10% success fee, $30 of that slot, and Sponsorshipped takes 25%, $75. Ask BuySellAds for its share in writing before you sign.
