Resend is a developer-first email platform that provides REST APIs and multi-language SDKs for programmatic transactional email dispatch. Its architecture natively integrates with React Email, enabling developers to write, preview, and render component-driven HTML email templates directly on server runtimes. The platform streams delivery event notifications—such as delivery confirmation, email opens, link clicks, and bounce events—to configured application webhooks using signed payload headers. Email deliverability and domain reputation are managed through automated SPF, DKIM, and DMARC DNS record validation alongside dedicated IP configuration options.
