Resend
Email API built for developers with React Email support
About Resend
Resend is a modern email API built for developers who are tired of dealing with legacy email services. Founded by Zeno Rocha, it focuses on developer experience first with clean, intuitive SDKs for Node.js, Python, Ruby, Go, PHP, Java, and more. Resend lets you send transactional emails using React components as templates through their React Email framework, so you can build beautiful emails using the same tools you use for web development. The API is simple: a single POST request with from, to, subject, and your React/HTML content. Resend handles deliverability, DKIM/SPF/DMARC configuration, bounce handling, and provides real-time webhooks for delivery events. The dashboard shows email analytics including open rates, click rates, bounce rates, and delivery status. It supports custom domains, dedicated IPs, email scheduling, batch sending, and attachments. The free tier includes 3,000 emails per month and 100 per day, making it perfect for side projects. For teams, it offers role-based access, audit logs, and multiple API keys with granular permissions.
