Newsletter sponsorships are direct deals between a creator and an advertiser — typically a logo, copy block, or dedicated section in an email send. Primary placements (top of email) command 1.5–2× secondary placement rates. Pricing is usually flat-fee per send or CPM-based. Sponsorships often yield the highest revenue per send for creators with engaged niche audiences. InfluencersKit includes a sponsorship management dashboard for tracking deals, deliverables, and performance.
