Create persistent mailboxes that you can use for long-term testing scenarios.

Example email addresses

# Example email addresses

Step 3: Configure SMTP Server

Configure your test application to use DevInbox SMTP server to trap all outgoing emails.

Configure your application's SMTP settings to use DevInbox's SMTP server. Use the mailbox email address as the username and your API key as the password for authentication.

SMTP Server Configuration

Host: smtp.devinbox.io
Port: 587
Username: your-mailbox@devinbox.io
Password: your-api-key

Step 4: Test Email Flow

Trigger email sending in your application and verify the emails in the DevInbox dashboard.

1. Configure your test application to use the SMTP server
2. Trigger email sending in your application (user registration, password reset, etc.)
3. Check the DevInbox dashboard for received emails
4. Verify email content, attachments, and formatting
5. Test different email scenarios (welcome, notifications, alerts)
