How Nostra and Opensend turned hidden traffic into $58k in recovered revenue

A joint solution for converting anonymous traffic into long-term revenue.

The challenge

Nostra’s Edge ID was already boosting site speed and sending high-quality traffic to ecommerce sites—but too much of that traffic still went unrecognized. Without persistent identity, brands struggled to personalize experiences and drive retention. Nostra’s extended cookie duration and improved recognition laid a powerful foundation—and by pairing it with Opensend’s identity resolution, brands can now convert more unknown visitors into long-term customers, unlocking the full potential of their traffic.
Without identity, brands couldn’t follow up, re-engage, or monetize interest after the visit ended. Money was being left on the table.

The strategy

The teams joined forces to close the loop:
Opensend resolved unknown traffic using its Reconnect tool—extending identity across sessions and syncing resolved contacts directly into Klaviyo for retargeting and lifecycle automations.
Nostra then layered on top, boosting cookie lifespan and recognition at the edge. By capturing and preserving user identity in real-time, Nostra enhanced Opensend’s reach—enabling better attribution and more personalized experiences for returning customers.
Together, the platforms turned previously unknown traffic into high-performing, long-term customer journeys.

The impact

Kut from the Kloth:
Identity match rate lifted 33%+
Captured thousands of incremental emails
Powered lifecycle flows that recovered $58K in revenue
No rebuilds. No disruption. Just two tools working in sync to maximize every visit.

Traffic is expensive. Identity is leverage.

Pairing site performance with real-time identity resolution gives brands a second shot at every visitor, and a way to compound paid performance.
“By combining Nostra with Opensend, we don’t just extend cookies—we extend visibility. That means more known users, longer attribution windows, and more revenue captured from traffic others miss—something no standalone platform can replicate.”
