Everything to know about your customers, in one place
With Klaviyo’s 350+ integrations, customer profiles consolidate data across your stack for a complete picture of each customer: who they are, what they like, and when and how they’re engaging with you.
All this customer profile data is for building segments and personalizing content, including:
- Purchase activity: orders placed and fulfilled, products ordered, loyalty points, and more
- Web activity: visits, product views, add to carts, site searches, review submissions
- Channel consent & engagement: email, SMS, push, reviews, ads
- Coupons: active, expired, redeemed
- Custom properties: interests, sizes, questionnaire responses
- Predictive analytics: CLV, churn risk, time between orders, next order date
Identity resolution for a truly accurate source of truth
Klaviyo protects you from conflicting, confusing, or incomplete data—with customer profiles that are detailed, accurate, and actionable.
Powerful web tracking
Web browsers limit client-side tracking to as short as 24 hours. Klaviyo’s server-side tracking keeps tabs on activity for up to a year, gathering valuable customer profile data without interruption.
Smart profile merging
Klaviyo automatically detects and merges duplicate profiles, even across multiple devices, for a crystal-clear view of each customer.
Anonymous activity backfill
Even before a customer is identified, Klaviyo captures each step of their journey. Once they sign up, their full history is instantly available, giving you a complete picture from day one.

Having one unified customer profile, where everything we know about a customer is in the same place—it’s huge. Now we see a customer’s journey, every touchpoint they get, and every way they interact with us, and we can act on that data.”
