Increase Inventory Value with Hashed Email Enrichment
Every ad impression contains signals. The more useful those signals are, the more valuable the impression becomes.
Retention.com helps publishers, SSPs, exchanges, and curation platforms enrich bidstream traffic with hashed email identifiers (HEMs) and additional identity signals that improve addressability, audience understanding, and advertiser targeting.
More identity. Better targeting. Higher-value inventory.
Make Every Impression More Addressable
Many impressions enter the marketplace with limited audience information. Retention.com helps enrich available traffic with hashed email identifiers and related identity signals that can be passed into advertising workflows. This allows buyers to better understand who may be behind an impression and connect inventory to audience strategies that rely on durable identifiers.
Improved audience addressability
Increased identity coverage
Stronger buyer match rates
Enhanced audience understanding
More valuable inventory
The Universal Identity Layer for Advertising
Hashed email identifiers have become one of the most important signals in modern advertising. They help connect inventory to identity frameworks, audience graphs, customer datasets, measurement systems, data clean rooms, and activation platforms. Adding HEMs to the bidstream creates additional opportunities for buyers to recognize and value inventory.
The result is greater utility for advertisers and increased value for publishers.
One Signal. Multiple Advertising Applications.
Hashed emails can serve as the foundation for connecting impressions to broader identity infrastructure. Using Retention.com's identity graph, enriched bidstream traffic can support audience matching, identity resolution, cross-device analysis, attribution, measurement, audience activation, and customer recognition.
The result is greater utility for advertisers and increased value for publishers.
