Full Accuracy Comparison
We believe in full transparency. It keeps us accountable and forces innovation. To achieve this objective, we tested all major email verification services against real email addresses to see which ones actually work. Below is a breakdown of every service's verification accuracy across major email providers, disposable email detection, and challenging edge cases. As the results show, VerifySwift delivers accurate verification across more scenarios than any other service.
Proof of Audit
To maintain transparency and accountability, we've recorded our complete testing process. The video shows real-time verification results from all services tested against the same email addresses. Watch it here, or contact us for the latest audit without obfuscation.
* Accuracy test conducted on January 11, 2026. All services tested against the same email addresses.
Note on disposable email detection: For disposable email services (like tempmail.so, emailondeck.com, and Emailnator), correctly identifying them as "disposable/unsafe" is shown as a checkmark (✓), while failing to detect them as disposable is shown as an X (✗). This is the reverse of regular email validation where checkmarks indicate the email is safe to use.
