## Configuration

The admin email is retrieved from (in order of priority):
1. `ADMIN_EMAIL` environment variable
2. First admin user in the database
3. `mail.from.address` configuration value

To set a specific admin email, add to `.env`:
```
ADMIN_EMAIL=admin@example.com
```

## Error Handling

All mail operations are wrapped in try-catch blocks with:
- Success logging: `Log::info()`
- Error logging: `Log::error()`
- Graceful failure - registration completes even if email fails

## Testing

To verify the implementation:
1. Register a new user through the registration form
2. Check admin logs for email sending confirmation
3. Verify the admin receives the email with all user details
4. Confirm password is visible in the email (for admin reference)
5. Test the "View in Admin Panel" button in the email

## Security Notes

⚠️ The password is sent to the admin in plain text for reference only.
- Ensure the admin email server is secure
- Consider adding email encryption for sensitive deployments
- The password should not be stored long-term by admin
- Users should change password on first login
- Only send to trusted admin email addresses
