ONLINE PLATFORMS & MARKETPLACES
Email advertising built for online platforms and marketplaces
From property portals like Zoopla to automotive marketplaces, job portals, and beyond – these platforms share a distinct advantage: a large, high-intent audience. And a common missed opportunity: email inventory that isn’t earning what it should.
That’s exactly what Passendo is built for.



Scale your platform's ad revenue with Passendo
You have the audience. You have the data. You know who your users are, what they’re looking for, and where they are in their journey.
Most platforms have the audience and the data, but lack the tooling to turn that first-party intelligence into a real email advertising operation.
Passendo closes that gap – with a dedicated email ad server that handles direct – sold campaigns, programmatic fill, audience segmentation, and reporting at scale.
