In their words
Their pitch	Email Verification is a pre-send process that systematically evaluates every email in a list through a combination of technical checks and proprietary algorithms to determine if it is syntactically correct, genuinely exists, and can successfully receive messages. Designed for email marketers, this validation step identifies and eliminates invalid, high-risk, or substandard addresses, thereby optimizing deliverability and safeguarding the successful transmission of your emails to target recipients.
