• Notifications and alerts
• System-generated emails from your app

Before You Start

Make sure you have:

Step 4: Configure a Sender Email in Resend

Before emails can be sent, you must verify a sender in Resend.

You can verify:

• A single email (e.g. no-reply@yourdomain.com), or
• An entire domain (recommended for production)

This sender is automatically used by CodePup.

Tip

Using a custom domain improves email deliverability and avoids spam filters.
