🎯 Purpose: Tags provide flexible contact categorization beyond traditional lists, enabling:
  • Dynamic segmentation based on behavior
  • Multi-dimensional contact grouping
  • Temporary or permanent categorization
  • Cross-team tag sharing (with isShareable flag)
💡 Use Cases:
  • Customer lifecycle stages (lead, prospect, customer, VIP)
  • Behavioral tags (engaged, inactive, power-user)
  • Product interests (feature-A-user, beta-tester)
  • Event attendance (webinar-2024-Q1, conference-attendee)
🔄 Tag Assignment: Tags can be assigned to contacts through:
  • API calls (contact creation/update)
  • Automation workflows
  • Manual bulk actions
  • Import operations
⚡ Best Practices:
  • Use descriptive tag names
  • Establish naming conventions
  • Regularly review and clean up unused tags
  • Consider tag hierarchies for complex segmentation
