Trait Activation Overview

Use Trait Activation to configure sync payloads that you send from Engage Audiences and Journeys to a Destination or Destination Function. Map traits from user profiles to Destinations, configure identifiers to sync, and choose a sync strategy that fits your use cases.

Trait Activation includes both Trait Enrichment and ID Sync. With Trait Enrichment, use custom, SQL, computed, and predictive traits to enrich the data you map to your destinations or destination functions. Use ID Sync to select identifiers and a sync strategy for each identifier when syncing Engage Audiences to Destinations.

Resyncs

Segment recommends creating a new audience for Trait Enrichment and ID Sync. For existing audience destinations, both Trait Enrichment and ID Sync won’t resync the entire audience. Only new data flowing into Segment will adhere to new trait settings.

Contact Segment support if you’d like your Audience resynced with Trait Enrichment and ID Sync.

Use cases

Trait Enrichment and ID Sync can help you:

• Increase advertising match rates: Expand the pool of users you advertise to and increase match rates by using traits and identifiers to find the right customers.

• Include more personalized message content: Include traits in your payload for more up-to-date, accurate data.

• Configure how you send identifiers to Destinations: Send the right identifiers to your destinations. For profiles with multiple identifiers, choose a strategy to select identifiers and send them downstream.
