# Email Configuration for SoundStudioPro

## Overview

SoundStudioPro now includes a comprehensive email confirmation system that sends detailed order confirmation emails after successful payments.

## Features

✅ **Order Confirmation Emails**: Detailed HTML emails with order details, billing information, and next steps  
✅ **Professional Design**: Beautiful, responsive email templates matching the brand  
✅ **Fallback Support**: Works with basic `mail()` function if PHPMailer is not available  
✅ **SMTP Support**: Full SMTP configuration for production use  
✅ **Error Logging**: Comprehensive logging for debugging  

## Email Content

Each confirmation email includes:

- **Order Details**: Complete breakdown of purchased items (credits and tracks)
- **Billing Information**: Customer's billing address and contact details
- **Order Summary**: Total amount, order number, and date
- **Next Steps**: Specific instructions based on what was purchased
- **Support Information**: Contact details and helpful links
- **Professional Branding**: SoundStudioPro logo and styling

## Configuration

### Current Setup

The system is currently configured to use the basic `mail()` function as a fallback, which works on most hosting environments.

### For Production (Recommended)

To use SMTP for better deliverability, update the settings in `config/email.php`:

```php
define('SMTP_HOST', 'smtp.gmail.com');           // Your SMTP server
define('SMTP_PORT', 587);                        // SMTP port
define('SMTP_USERNAME', 'your-email@gmail.com'); // Your email
define('SMTP_PASSWORD', 'your-app-password');    // Your app password
define('SMTP_FROM_EMAIL', 'noreply@soundstudiopro.com');
define('SMTP_FROM_NAME', 'SoundStudioPro');
```

### Gmail Setup

1. Enable 2-factor authentication on your Gmail account
2. Generate an App Password:
   - Go to Google Account settings
   - Security → 2-Step Verification → App passwords
   - Generate a password for "Mail"
3. Use the generated password in `SMTP_PASSWORD`

### Other SMTP Providers

The system supports any SMTP provider. Common configurations:

**SendGrid:**
```php
define('SMTP_HOST', 'smtp.sendgrid.net');
define('SMTP_PORT', 587);
define('SMTP_USERNAME', 'apikey');
define('SMTP_PASSWORD', 'your-sendgrid-api-key');
```

**Mailgun:**
```php
define('SMTP_HOST', 'smtp.mailgun.org');
define('SMTP_PORT', 587);
define('SMTP_USERNAME', 'your-mailgun-username');
define('SMTP_PASSWORD', 'your-mailgun-password');
```

## How It Works

1. **Payment Processing**: When a customer completes payment, billing and order data is stored in the session
2. **Success Redirect**: After successful payment, customer is redirected to checkout success page
3. **Email Trigger**: The success page automatically triggers the confirmation email
4. **Email Generation**: A beautiful HTML email is generated with all order details
5. **Email Sending**: Email is sent using configured SMTP or fallback mail() function
6. **Logging**: All email activities are logged for monitoring

## Testing

### Test Email Generation
```bash
php -r "require 'config/email.php'; 
\$test_data = ['total_amount' => 2998, 'cart_summary' => [['type' => 'credit', 'name' => 'Starter Package', 'quantity' => 1, 'amount' => 1999]]]; 
\$test_address = ['billing_first_name' => 'John', 'billing_last_name' => 'Doe', 'billing_email' => 'test@example.com', 'billing_address' => '123 Test St', 'billing_city' => 'Test City', 'billing_state' => 'TS', 'billing_zip' => '12345', 'billing_country' => 'US']; 
\$email = generateOrderConfirmationEmail('John Doe', \$test_data, \$test_address); 
echo 'Email generated successfully. Subject: ' . \$email['subject'];"
```

### Test Email Sending
```bash
php -r "require 'config/email.php'; 
\$result = sendEmail('test@example.com', 'Test User', 'Test Email', '<h1>Test Email</h1><p>This is a test email from SoundStudioPro</p>', 'Test Email - This is a test email from SoundStudioPro'); 
echo 'Email send result: ' . (\$result ? 'SUCCESS' : 'FAILED');"
```

- `stripe_webhook.php` - Webhook handler for Stripe events (alternative approach)
- `checkout.php` - Success page email triggering
- `process_credit_payment.php` - Payment data storage for emails

## Troubleshooting

### Email Not Sending
1. Check error logs: `tail -f /var/log/apache2/error.log`
2. Verify SMTP credentials
3. Test with basic mail() function first
4. Check server mail configuration

### Email Not Received
1. Check spam/junk folders
2. Verify sender email address
3. Test with different email providers
4. Check email deliverability settings

### SMTP Issues
1. Verify SMTP credentials
2. Check firewall settings
3. Test SMTP connection manually
4. Use alternative SMTP providers

## Security Notes

- Store SMTP credentials securely
- Use environment variables for production
- Enable SSL/TLS for SMTP connections
- Regularly rotate app passwords
- Monitor email logs for suspicious activity

## Future Enhancements

- Email templates customization
- Multiple language support
