Monetize Your Newsletter with MailAdx Publisher Platform
MailAdx SSP gives newsletter operators a complete inventory layer — build ad placements, set price floors, accept direct deals, and connect to programmatic demand, all from a purpose-built publisher portal.
Stop leaving ad revenue on the table
Most newsletter publishers monetise with one or two direct sponsors and a referral link. MailAdx changes the economics: programmatic fill kicks in for every send slot that a direct sponsor doesn't fill, house ads cover any remaining inventory, and the system optimises floor prices automatically based on fill data. The result is near-100% monetisation of every impression.
- Automated floor price optimisation based on historical fill
- Programmatic fallback fills unsold inventory
- House ad support for promotional slots
A publisher portal your operations team will actually use
The MailAdx Publisher Portal is designed for non-technical newsletter teams. Create placements, review pending deal requests, approve creatives, check this week's revenue, and download invoices — all without opening a developer console. Copy the ad tag from Dashboard → Ad Units and paste it into your ESP template once.
- Creative approval workflow with one-click accept/reject
- Revenue calendar with send-by-send breakdown
- CSV export for finance reconciliation
