Loops Information

Loops is the email platform for modern SaaS companies: transactional, marketing, and lifecycle email in one product, with one API and one contact record. Most software companies run two or three email tools: one for password resets and receipts, another for campaigns, a third for onboarding flows. Loops replaces the stack: a REST API and SDKs (JavaScript, Go, Nuxt, PHP, Ruby) for developers, a clean editor for marketers, and workflows that react to what users actually do in your product. Loops is also built for the agent era. Published skills for Claude Code, Cursor, and Codex, a CLI, llms.txt, and an OpenAPI spec mean an AI coding agent can install Loops and reach a working send without human correction.
