Marketing personalization FAQs
Learn how Klaviyo unifies customer data and uses it to personalize every message down to the individual, across every channel.
What data do I need to personalize at scale?
Klaviyo builds one real-time profile per customer from the data you already have: orders, site activity, cross-channel marketing engagement, and any custom properties you pass in. Segmentation logic, flow triggers, and AI all read from that complete profile instead of a single channel's slice.
How do I create customer segments from my data?
In Klaviyo, you can build a segment from any mix of events, properties, and predictive data, with no query language or engineering needed. Segments update automatically as behavior changes, so a group like lapsed VIPs or frequent browsers always reflects who currently qualifies.
How do I personalize email and SMS without spamming subscribers?
Klaviyo AI lets you personalize the content, offers, channel mix, and send time of your messages based on each individual subscriber’s behaviors and predictive properties.
How do I build flows that change based on customer behavior?
Klaviyo flows can branch on any profile property or event, so a customer's path shifts based on their unique history with your brand. Branching lets one flow serve many audiences, delivering the right next message instead of the same sequence to everyone.
