Resend

Resend is an email API service that helps developers send emails from their applications. Think of it as the delivery system for your app's emails - whether that's password resets, welcome messages, or marketing campaigns.

The platform offers two main services: sending individual emails through their API, and sending marketing emails to groups of contacts. You can use any programming language, as Resend provides ready-made code libraries for Node.js, Python, Ruby, Go, PHP, Java, and more.

One standout feature is the React Email integration. This lets you build email templates using React components, which is much easier than writing traditional HTML email code. Resend also includes tools to track delivery, monitor email opens and clicks, and ensure your emails reach inboxes instead of spam folders.

Getting started with Resend is straightforward. Here's how to begin sending emails:

• Sign up at Resend and verify your email address. Then add your custom domain in the dashboard and complete the DNS verification process.

• Create an API key from the dashboard. This key connects your application to Resend's service. Keep it secure and never share it publicly.

• Install the Resend library for your programming language. For example, use npm for Node.js or pip for Python.

• Write code to send your first email. Import the Resend library, add your API key, and call the send function with the sender, recipient, subject, and message content.

• For React projects, create email templates using React Email components. Design your email as a React component, then pass it to Resend's send function.

• Check the dashboard to track sent emails, view delivery status, and monitor any issues. Use webhooks to get real-time updates about email events in your application.
