Summary
The phenomenon of orders being placed with @dummy.email addresses is complex, stemming from a mix of legitimate testing practices, user privacy concerns, and potentially malicious activities. The domain itself is likely squatted and these email addresses are non-functional, indicating they are not used for genuine communication. The use cases range from developers using them in testing environments to avoid real emails, individuals bypassing signup requirements, to fraudulent attempts such as validating stolen credit card data or bot sign-ups. The presence of these addresses can distort marketing analytics and compromise data quality. Consequently, a multi-faceted approach involving security enhancements, code review, data validation, and careful monitoring is crucial to address the issue effectively.
Key findings
- Domain Status & Functionality: @dummy.email is likely a squatted domain with non-functional email addresses.
- Testing & Development: Dummy emails are used for testing in development environments to prevent sending real emails.
- User Privacy & Bypass: Some users use dummy emails to avoid providing personal information or bypass signup requirements.
- Potential Fraud & Exploits: Orders with @dummy.email may indicate fraudulent activities (CC validation, bot sign-ups) or exploits in the client's code.
- Analytics Distortion: Dummy emails can skew marketing analytics, affecting the accuracy of campaign performance.
- Data Validation Importance: Proper data validation and sanitisation are crucial for application security.
Key considerations
- Review Purchase Metadata: Analyse purchase metadata, including IP addresses, to identify potential fraud patterns.
- Code & Security Audit: Conduct a code and security audit to identify and address potential vulnerabilities, particularly in data validation processes.
- Enhanced Security Measures: Implement security measures such as CAPTCHA, email verification (double opt-in), and stricter validation to prevent bot sign-ups and fraudulent activity.
- Data Sanitisation & Testing: Sanitise test data, replacing dummy emails with valid examples like @example.com and ensure compliance with data protection laws when the data involves real individuals.
- Analytics Cleansing & Monitoring: Clean email lists to remove dummy emails, improve the accuracy of marketing analytics, and continuously monitor for suspicious patterns.

What the documentation says
5 technical articles
The documentation highlights best practices for handling data, especially in testing environments. Reserved domains like example.com are designated for safe use in documentation. Proper data validation and sanitization are crucial for application security, avoiding reliance on dummy data. Setting up test email accounts with mock servers or discard configurations allows safe testing without impacting real users. Adherence to data protection rules is essential when test data involves real individuals.
Key findings
- Reserved Domains: Domains like example.com are specifically reserved for documentation and should not resolve to live servers.
- Data Validation Importance: Data validation is crucial for application security, minimizing the use of dummy or invalid data.
- Email Testing Methods: Test email accounts and mock SMTP servers are effective for testing email functionality without sending to real users.
- Data Protection: Data protection rules must be followed when using data, especially if it refers to real individuals.
Key considerations
- Sanitize Data: Ensure you sanitise your test data where it relates to real individuals
