Optimove launched Zero Copy Customer Lists on Oct. 26, 2026, allowing brands to build marketing audiences from data in their Snowflake environments without copying sensitive customer fields into Optimove. The feature is in open beta and is rolling out incrementally to Optimove customers.

Key Takeaways

  • The feature can use fields such as credit scores, KYC status and internal risk-model outputs to define an audience.
  • Snowflake returns matching customer IDs to Optimove; the underlying sensitive fields remain in the warehouse.
  • Customers can run a query once or schedule recurring updates.

How Zero Copy Customer Lists works

Marketers connect Optimove to their Snowflake environment and create a list in Optimove Data Studio using a SQL query that returns customer IDs. Saving the list creates an audience that can be refined with additional criteria already held in Optimove.

The query runs inside the brand’s warehouse, and Optimove receives the IDs that match its criteria rather than the sensitive fields used to select them. A scheduled query reflects the warehouse’s data at the time of each sync.

Availability and limitations

Optimove said the capability is in open beta and is being rolled out incrementally to its customers. The announcement did not give a date for wider availability.

The feature is designed for brands using Snowflake. It keeps the queried customer data in that environment, though matching customer IDs are returned to Optimove for audience creation.
