What Can VerfMail Do? Key Features
Up to 72% Cheaper
VerfMail offers the same high-quality email verification as competitors but at a fraction of the price.

This makes it an economical choice for businesses looking to save on email validation costs without compromising on quality.
Detailed Reports
Unlike other services that simply mark emails as invalid, VerfMail provides specific reasons for each failure. These reasons include 'No MX records,' 'SMTP reject,' 'Disposable email provider,' and more. This level of detail helps businesses understand and address issues in their email lists effectively.
Lightning Fast Processing
VerfMail can process up to 50 emails per second, thanks to its parallel verification system. This means a list of 10,000 emails can be verified in under 4 minutes, significantly faster than many competitors who process only 20-30 emails per second.
