Description
Relay is a full-stack email management platform built on top of the Resend API. It gives developers and teams a centralized dashboard to provision custom sending domains with automatic DNS verification, design JSX-based email templates with live Monaco editor preview, compose and dispatch transactional emails, and monitor real-time delivery events — all without writing a single line of SDK boilerplate. Built with Next.js 16, Drizzle ORM, NeonDB, and Better Auth, Relay abstracts away the hardest parts of email infrastructure so teams can focus on what they write, not how they send it.
