FAQ

Common questions

  • Should I stop using Klaviyo if I use Persona LM?

    No. Persona LM prepares segments for Klaviyo activation. They're complementary — Persona LM discovers the segments, Klaviyo delivers the emails. You'll send better campaigns because you're targeting behavioral segments instead of rule-based lists.

  • Klaviyo already has predictive analytics — how is Persona LM different?

    Klaviyo's predictive analytics scores individual profiles on email engagement (predicted CLV, churn risk). Persona LM discovers buyer segments from purchase behavior and predicts what each segment buys next. Different data, different granularity, different output.

  • Can Persona LM create segments I can't build in Klaviyo?

    Yes. Klaviyo segments are based on properties and events you define — 'purchased product X in last 30 days.' Persona LM finds patterns across your entire order history that you wouldn't know to look for — like a segment of buyers who buy full-price basics every 6 weeks and never engage with email but have 3x the LTV of your engaged subscribers.

  • How do the audiences sync?

    Persona LM prepares the segment export and operator brief for Klaviyo activation, with refreshed evidence after each sync.
