The Data Sync Contacts section displays all contacts that have been imported into the platform from external systems — such as CRMs, email marketing tools, or other integrated platforms — via data sync.
These are contacts pulled into your system through a connected integration, not tracked directly via your pixel. Examples include:
Contacts from your CRM (e.g. Salesforce, HubSpot)
Subscribers from email platforms (e.g. Mailchimp, Klaviyo)
Leads from ad tools or CSV uploads
Each synced contact typically includes:
Email / Phone number
External ID (if available)
Original platform (e.g. “HubSpot CRM”)
Date synced
Matched status (if matched to a pixel-tracked user)
Behavioral enrichment (if any actions were later detected via the pixel)
Audience expansion:
Combine external leads with behavior-tracked users to create powerful hybrid audiences.
Better targeting:
Segment imported contacts based on source, attributes, or sync time.
Cross-platform insight:
See how synced users behave on your website even if they weren’t originally tracked by the pixel.
If a synced contact visits your site later and gets tracked by the pixel, they become a resolved and enriched contact — allowing you to:
See historical sync info + real-time behavior
Use them in lookalike audiences
Sync them back to ad platforms with complete profiles
Import lead lists from HubSpot, Salesforce, or CSV.
Match marketing email subscribers with site behavior.
Enrich synced users with data from Smart Audiences or Lookalikes.
Filter by integration (e.g., “only contacts from Mailchimp synced this month”).
Regularly review new synced contacts and match them to tracked visitors.
Combine with Smart Audiences for targeted outreach.
Use filters to identify contacts who haven’t yet visited the site (good retargeting candidates).
