Automate revenue: Launch high-intent flows (welcome, abandoned cart, browse, winback, back-in-stock) and send segmented campaigns with A/B testing and attribution.
Two-way support & sales: Manage replies in Postscript or route conversations to help desks like Gorgias and Zendesk.
Plug into your stack: Deep Shopify ecosystem integrations (Klaviyo, Recharge, AfterShip, Junip, and more).
Simple pricing & fast start: Free trial, transparent per-message rates, and dedicated CSM support on higher tiers.
