Treat catch-all as uncertainty, not validity. Confirm the prospect and search for person-specific evidence before deciding on a contact route.
Why was the result marked catch-all?
The server responded to the named candidate and a random control in a way that did not establish a difference. Because a made-up address could receive the same response, Ruvio does not present the named mailbox as likely existing.
How do I review the contact?
Prioritize the review only if the company and role are a strong fit. Check the person's current employment, the official domain, first-party team pages, credible professional sources, and any exact public listing.
Confirm current role and employer.
Confirm the official company domain.
Look for the exact address in a credible professional source.
Use a public general inbox or another channel when it is the better-supported route.
Keep unresolved candidates separate from likely-existing contacts.
Can I send to a catch-all address?
A catch-all result alone is not enough to recommend standard outreach. Any decision to contact an unresolved address needs a legitimate business reason, human review, a small controlled approach, and compliance with applicable rules. A later delivery event may add evidence; a hard bounce should trigger suppression.
