> Email API for developers to send transactional and marketing emails at scale with high deliverability.

Resend is a modern email sending platform built specifically for developers. It provides a simple, elegant API to send transactional and marketing emails at scale while ensuring messages reach inboxes instead of spam folders. The platform offers SDKs for popular programming languages including Node.js, Python, Ruby, PHP, Go, Rust, Java, Elixir, and .NET, plus REST API and SMTP support.

- **Developer-First API** - Integrate email sending in minutes with clean SDKs for all major programming languages and frameworks like Next.js, Remix, Nuxt, Express, and more.

- **React Email Templates** - Build beautiful email templates using React components instead of dealing with complex table layouts and HTML, powered by the open-source react-email library.

- **Test Mode** - Simulate email events and experiment with the API without accidentally sending real emails to real recipients.

- **Modular Webhooks** - Receive real-time notifications when emails are delivered, opened, bounced, or links are clicked.

- **Contact Management** - Import and manage contact lists of any size with full visibility into each contact and their personal attributes.

- **Broadcast Analytics** - Gain insights into how audiences interact with broadcast emails through comprehensive analytics and reporting.

- **Deliverability Features** - Proactive blocklist tracking, DKIM/SPF verification, DMARC policies, BIMI support, and managed dedicated IPs with automatic warm-up.

- **Multi-Region Sending** - Send emails from regions closest to users including North America, South America, Europe, and Asia for reduced delivery latency.

- **Enterprise Security** - SOC 2 Type II compliant, GDPR compliant, with data encryption at rest (AES-256) and in transit (TLS), plus DDoS protection.

To get started, sign up for a free account, verify your domain with DNS records, and integrate using your preferred SDK. The platform provides detailed logs, intuitive analytics, and domain authentication tools to manage email sending effectively.
