Email quality
Email Verifier
Check email quality before export with syntax, disposable-domain, domain, MX-level, and SMTP mailbox-level signals attached to the lead row.
Check MX-level domain signals
Disposable-domain, domain, and MX checks help identify addresses from risky, parked, or unreachable mail domains.
Run SMTP mailbox verification
SMTP-level checks help separate safe, risky, catch-all, blocked, and invalid mailbox responses where the server allows it.
Send cleaner CSVs
Filter by MX and SMTP status before moving the list into outbound tools or a shared workspace.

Email Verifier is the cleanup pass after Email Finder: first confirm the domain can receive mail, then check the mailbox response where SMTP is available.

Run syntax, disposable-domain, domain, MX-level, and SMTP mailbox-level checks.
