# Contact Data product

The Contact Data product focuses on contacts/members data. It offers a single, reliable contact list that everyone can use to personalize communication and improve customer engagement

<Tip>
  The previously nested `value_json` (VARIANT) field has now been expanded into explicit, typed columns that reflect the actual columns delivered to the tenant catalog.
</Tip>

**Tenant column:**`tenant_id`\
**Description:** The table contains contact/member records. Each row represents a contact with its detailed attributes flattened into dedicated columns — identity and profile fields (names, email, phone, address), membership and marketing metadata, and registration/creation timestamps. This data can be used for:

* building a single reliable contact list for personalization
* analyzing contact management processes and engagement
* tracking changes over time via the timestamp fields
* integrating contact data with other systems
