Boostr and Passendo Announce Strategic Partnership to Unify Ad Management for Publishers’ High-Value Email Inventory

Joint solution provides publishers a single source of truth to streamline campaign lifecycles and gain real-time performance insights across premium email and digital channels.

Boostr, the leading unified Ad Management Platform for media businesses, today announced a partnership and integration with Passendo, a global leader in Email Ad Serving. This collaboration will enable media publishers to seamlessly manage, forecast, and execute their high-demand newsletter and email advertising campaigns directly within the Boostr platform.

The integration connects Boostr’s platform with Passendo's dedicated email ad server and monetization tools. This provides a single source of truth for publishers, allowing them to overcome operational complexity and maximize revenue across all their ad channels, including premium email inventory.

Key Benefits of the Integration for Publishers:

• Centralized Inventory and Forecasting Across All Channels: Publishers can now manage, package, and forecast email inventory, both direct-sold or programmatic, within the same system they use for display and native. Everything in one place.
• Streamlined Cross-Team Workflows: Sales, Ad Ops, and Rev Ops teams benefit from automation across the full campaign lifecycle using Boostr’s automated workflows for efficient campaign planning, delivery, and billing, and plan both direct-sold and programmatic email ad campaigns via Passendo.
• Consistent, Accurate Data: The partnership ensures that accurate performance data and revenue reporting from Passendo are fed directly into Boostr’s comprehensive platform, enabling smarter strategic decisions.

Patrick O'Leary, Founder & CEO of Boostr commented on the announcement, “Email newsletters have proven to be a critical, high-engagement channel for publishers, but managing that revenue stream often exists in a silo. By integrating with Passendo, we are fulfilling our mission to conquer media business complexity. Our joint clients can now centralize their entire ad operation, from first pitch to final reconciliation, ensuring no revenue is left on the table in this vital channel.”

Anders Rasmussen, Founder & CCO at Passendo, added: “If you're looking to maximize your revenue from email advertising, this partnership delivers a major step forward.
