Connect Sailthru to sync behavioral signals and drive retention.

Sailthru (by Zeta Global) is an email and marketing personalization platform that helps brands deliver individualized customer experiences across email, web, and mobile channels. Sailthru uses data and predictive analytics to automate and optimize marketing campaigns, enabling companies to send the right content to the right person at the right time.

Sailthru provides the messaging infrastructure and lifecycle triggers, tracking campaign-level metrics like open and click-through rates. Subsets adds the missing layer of predictive intelligence, real-time orchestration, and automated experimentation, enabling lifecycle teams to act on behavioral signals without waiting on manual segmentation, data pulls, or engineering support.

Predictive Audiences for Retention & Upsell: Subsets segments subscribers and pushes the audiences directly to Sailthru to trigger the right LO Flows at the right time.

Smarter Lifecycle Optimizer Flows: Subsets enriches LO Flows with deeper context around how each flow impacts retention, LTV, and long-term engagement, giving lifecycle teams a clearer picture of what drives sustainable growth.

End-to-End Testing: Subsets manages the full testing lifecycle by selecting audiences, splitting variants, and pushing treatment groups to Sailthru via custom IDs that trigger LO Flows. Results are tracked and analyzed in Subsets.
