Test Date: January 25, 2026
Note: For disposable email detection, a checkmark (✓) means the service correctly identified the email as disposable/unsafe. An X (✗) means it failed to detect the disposable email. For the Emailnator row, some services show two results separated by a slash (e.g., ✓ / ✗) because we tested with two different email formats.
Video Proof: Watch the complete test recording showing real-time results from all services.

Remember: While our free checker beats the competition for basic validation, it doesn't verify actual deliverability. For email campaigns and list cleaning, you need VerifySwift's deep verification which outperforms all paid competitors too!
