Resend
Resend is an email API built for developers to send transactional and marketing emails from applications. It provides a simple REST API, official SDKs for multiple languages, and a web dashboard to compose, test, and monitor email delivery. Resend supports custom domains with automatic DNS configuration, email templates with React components, webhooks for delivery events, team collaboration, and detailed analytics on opens, clicks, and bounces. It handles authentication, deliverability infrastructure, and compliance so developers can integrate email sending without managing SMTP servers or complex email service configurations.
