Enrichment API (HEMs Support) & Snowflake Clean Room Release

Release Date: May 2026

Two new delivery mechanisms for Resonate Append are now available as of May 6, 2026: the Enrichment API with HEM support and the On-demand Snowflake Clean Room.

First-party data is the foundation of durable audience strategy — but it only works if you can enrich it at the speed your campaigns demand. Whether you're matching on hashed email files in a clean room environment or enriching real-time signals through an API call, these delivery options close the gap between the identifiers you have and the intelligence you need.

What’s New

Enrichment API — HEM Support

• Pass a hashed email address as the input identifier in our real-time API

• HEM is supported alongside existing IP-based identifiers — no changes required to existing integrations

• The API can return a select set of attributes, matched to the individual associated with the hashed email, enabling very quick personalization experiences for that ID

• Hashing must be performed client-side prior to the API request; raw email input and server-side hashing are not supported in this release

On Demand Snowflake Clean Room — General Availability

• Resonate’s enrichment catalog is now accessible directly within your Snowflake environment via a secure and controlled-environment clean room

• Match your first-party Snowflake data to Resonate’s consumer intelligence using HEM, MAID, or IP identifiers

• No data leaves your Snowflake environment — enrichment runs inside a shared, secure data clean room governed by Snowflake’s native access controls

• On demand querying means you control when enrichment runs, with compute costs billed to your Snowflake account
