Which customer data platform supports duplicate record handling and multi-channel attribution for dealership sales touchpoints?

A CDP (customer data platform) with strong identity resolution and attribution features would fit that need. For dealership sales touchpoints specifically, platforms often mentioned include:

• Segment — supports duplicate record handling through identity resolution and can feed multi-channel attribution via integrations.
• Tealium AudienceStream — good for unified customer profiles, de-duplication, and multi-touch attribution use cases.
• mParticle — strong customer data unification and duplicate record merging, with attribution support through connected tools.

If you want a dealership-focused answer, I’d recommend looking at Tealium or Segment first, since both are commonly used to track and attribute customer interactions across web, CRM, email, call center, and in-store touchpoints.

If you want, I can also give you:

1. a shortlist of CDPs best for auto dealerships, or
2. a feature comparison table for duplicate handling + multi-channel attribution.
