Loops Email Platform

Loops is an email platform designed for SaaS companies that unifies product emails, marketing campaigns, and transactional messages into a single system. Founded by Lachlan Campbell and the Loops team, the platform provides a visual email editor with a block-based interface for designing responsive emails without HTML knowledge, along with a code editor for custom designs. Loops organizes contacts with properties and events for audience segmentation, and provides lifecycle workflow automation triggered by user events, schedule delays, and conditional logic. The platform integrates with popular developer tools including Supabase for authentication events, Clerk for user management, Stripe for billing events, PostHog for product analytics, and Vercel for deployment notifications. SDKs are available for Node, NextJS, Ruby, PHP, Nuxt, and Laravel for programmatic email sending, and a REST API enables integration from any backend. Loops is used by companies including Framer, Linear, Perplexity, Clerk, and Y Combinator startups for their email infrastructure. The platform handles deliverability through managed IP infrastructure, bounce handling, unsubscribe management, and compliance with CAN-SPAM and GDPR requirements. Pricing scales based on contact count rather than email volume, with a free tier for up to one thousand contacts.
