Basic scrubbers only check if a domain has an MX record. True email list scrubbing interrogates the destination mail exchange and cross-references multi-million-domain threat feeds without tripping anti-harvesting firewalls.
Identifies recycled trap patterns, honeypot role prefixes (abuse@, noc@, security@), and gibberish local-parts generated by bots.
Separates guaranteed valid mailboxes from corporate accept-all domains so your cold outreach domains stay below a 1% bounce rate.
Scrub complex .XLSX workbooks with multiple tabs and download the cleaned database with all original sheets and formulas preserved.
Email list scrubbing is the process of auditing a contact database to remove invalid, undeliverable, disposable, duplicate, role-based, and high-risk catch-all email addresses before sending marketing or sales campaigns.
KaijuVerifier scrubs 5,000 contacts for a $19 one-time payment (credits never expire), 10,000 contacts/mo for $19/mo, or 50,000 contacts/mo for $49/mo — up to 88% less than legacy scrubbing agencies.
