- No audited case studies with verified ROI, retention, deliverability improvements, or standardized ad yield metrics were located in the reviewed public materials.
- Reported platform-level revenue and newsletter-count figures in media coverage are secondary-source reports; buyers should request primary metrics and references where needed.
Recommendation for buyers focused on monetization: request median sponsor CPM ranges, example payout statements, Boosts marketplace benchmarks, deliverability metrics and SLAs, and references from publishers of comparable size.
