Visit WebsiteAbout this product
Resend is the email API built for developers who want to send transactional and marketing emails with confidence.
Unlike legacy SMTP providers, Resend was designed API-first with a modern SDK for Node.js, Python, PHP, Ruby, Go and more. You write emails with React Email — a component-based email authoring system — and deploy in minutes.
Resend handles deliverability, SPF/DKIM/DMARC configuration, bounce tracking and analytics automatically. It's used by thousands of startups and developer tools companies.
Key Features
- Modern REST API with SDKs for 7+ languages
- React Email component library for HTML emails
- Automatic SPF, DKIM and DMARC configuration
- Bounce, open and click tracking out of the box
