MailAdx
Real-time bidding for newsletter ad inventory
Most newsletter ad networks were built for display web, then awkwardly retrofitted for email. MailAdx is built from the ground up for newsletters — no cookies, no tracking pixels that break in inboxes, just real-time bidding (RTB) that matches your sends with relevant advertisers automatically. If you run a newsletter, MailAdx plugs into your existing send flow, auto-inserts ad placements, and lets demand bid for your inventory in real time — so you earn more per send without chasing sponsors.
Hey Product Hunt! 👋
Most ad networks for newsletters are basically display-web ad tech with an email wrapper bolted on — third-party cookies that don't work in inboxes, tracking pixels that get blocked, and bidding logic that wasn't built for how newsletters actually get sent.
We built MailAdx from scratch for newsletters: cookieless, real-time bidding that matches your sends with relevant advertisers automatically. If you're running a list with 1M+ subscribers, it plugs into your existing workflow and lets demand bid for your inventory in real time — so you earn more per send without manually chasing sponsors.
We're bootstrapped, early-stage, and building in the open. Would love your feedback — especially from anyone running a large newsletter who's tried (and been frustrated by) existing ad networks.
