How To Enable The Integration
Set up the Replit integration for Mailgun in minutes
Set up the integration and start sending emails in minutes. This example walks through sending a welcome email when a new user signs up—but the same principles apply to any user action or trigger.
For a comprehensive step-by-step guide, see the Mailgun + Replit Integration Guide.
Step 1: Build your app in Replit – Create a project that handles user actions (signups, form submissions, etc.) using Replit’s editor.
Step 2: Set up Mailgun credentials – Sign up at Mailgun.com, verify your sending domain by adding DNS records, and generate a private API key from Settings > API Security.
Step 3: Connect Mailgun to your Replit project – Open your project and ask the Agent: “Enable email sending via Mailgun.” Replit will prompt you to provide your Mailgun API key and verified domain—these are securely stored as project secrets and the integration is provisioned automatically.
Step 4: Test and deploy – Trigger a test email action in your app and verify it arrives in your inbox. Once working, deploy your Replit project.
