Catch-all domains accept mail for any address, making it impossible for traditional verifiers to check if a specific mailbox exists. MillionVerifier flags these as "Risky". OrbiSearch resolves them.
OrbiSearch
Proprietary dual-layer mailbox detection determines whether individual mailboxes exist on catch-all domains. Returns a definitive result in seconds without sending any emails.
11.5x more catch-all emails resolved
MillionVerifier
Classifies catch-all emails as "Risky" without checking mailbox existence. Does not charge credits for these results, but provides no actionable information. For catch-all resolution, they partner with third-party Scrubby (24-72 hours, sends test emails).
25-30% of "Risky" flags are actually valid emails
2,451 confirmed catch-all emails from a real cold outreach campaign, tested through both services.
