Loop Flows lets merchants create subscription workflows with IF-THEN logic without code. The app lists integrations including Klaviyo, Postscript, Attentive, Yotpo, Gorgias, Zendesk, Rebuy, and Google Analytics. Installation takes place through a Shopify account and selected store. The Free plan costs nothing and covers 50 active subscriptions, with a mobile-friendly customer portal, subscription alerts, and growth and revenue analytics. Starter costs $99 a month, billed every 30 days, and lists a 1.0% per-transaction rate; Pro costs $399 a month, billed every 30 days, and lists 0.75% per transaction. Both list a 14-day free trial.
