This guide covers how marketers can leverage Segment to build unified customer profiles and power personalized marketing at scale.

Whether you need to unify customer data across channels, build audiences for targeting, or ensure consistent tracking across your marketing stack, this guide provides practical approaches for using Segment effectively.

How Identity Works 2026

Identity Resolution Flow:

1. Anonymous visitor arrives

   → anonymous_id linked to user_id

3. Same user on mobile
   → Different anonymous_id
   → Identify links to same user_id

4. User emails clicked
   → External IDs linked
   → Complete profile unified

Unify Features 2026

• Cross-device: Merge web, mobile, IoT identities
• Cross-channel: Link email, ads, in-app
