About
Loops is the modern email platform purpose-built for software companies, offering a unified solution for marketing email, product email, and transactional email. Designed with simplicity and developer experience in mind, Loops makes it easy to go from idea to inbox in minutes — without sacrificing power or flexibility. At its core, Loops features a best-in-class email designer that renders consistently across all major email clients. Its data model is built around contacts, contact properties, events, and event properties — making it intuitive for developers to instrument and trigger emails from their applications via a clean REST API and official SDKs for Node, Next.js, Ruby, PHP, NuxtJS, and Laravel. Loops' lifecycle automation (called "Loops") lets teams build powerful multi-step email sequences triggered by user events — with branching logic, delays, filters, and exit conditions. Segments can be built from contact properties and behavioral data, kept in sync with the product in real time, and reused across campaigns and automations. For growth teams, Loops provides goal conversion tracking, experiment tooling, and a clear view of which emails drive upgrades, reduce churn, and generate revenue. The platform integrates natively with Supabase, Clerk, Stripe, PostHog, Zapier, Segment, Webflow, Framer, Bubble, and more. Loops is free to start with no credit card required, making it accessible for startups from waitlist to IPO.
