"Not SaaS. Not an API. A professional tool that truly runs on your computer."
Why Do SaaS Tools Misclassify Your Valid Emails?
We ran a head-to-head test on 140,026 real emails. The results are shocking.
SaaS Misclassification by Domain (10,180 valid emails wrongly flagged)
10,180 valid emails incorrectly marked "invalid"
12,818 out of 12,849 incorrectly marked as invalid
Root Cause:SaaS verification servers use shared public IPs. Once flagged by Microsoft, Apple, and other mail providers, those IPs get blocked in bulk — causing valid emails to return "unknown state" errors.
MailVerifyAI's Solution:Verify from your own machine. SOCKS5 proxy rotation lets every request use a unique IP.
