case study inside: 72 fund managers touched · 24 dead mailboxes caught pre-send · ~2% bounce
Apollo sells you 240 million contacts.Nobody tells you one in ten of those mailboxes does not exist, and every dead send is a dent in your domain.
verdict was built after burning exactly that way
How it works
Pattern inference from the public web. No contact database, no credits, no scraped lists. Verdict reads what companies publish about themselves and infers the rest.
Every candidate gets an SMTP probe before anything ships. Catch-all domains flagged. Enterprise gateways detected. Dead mailboxes stamped and suppressed forever.
Only what passed the gate leaves your domain. Person-level cooldowns, suppression lists, and follow-up eligibility are enforced by the engine, not by your discipline.
