Check an email before you send (Abstract)

Liveby Abstract

Checks one email address: whether it can receive mail (format, MX and SMTP), a quality score from 0 to 1, risk flags (disposable, role, free provider), how many known data breaches include it, and the sender's organization.

Use it to clean a lead list before a campaign.
