Voila Norbert finds email addresses and scores them. Finder confidence reflects discovery accuracy, not inbox status.
Voila Norbert is an email finder that helps outbound teams locate professional email addresses for specific people at specific companies. It takes a name and domain as inputs, discovers the most likely email address for that contact, and assigns a confidence score based on how well the result matches expected patterns and available signals.
Voila Norbert's confidence score measures how reliable the discovery was β how consistently that address appears in the data available to the finder at the time of the query. A high score means the finder is confident in the pattern it used. It does not confirm that the mailbox is currently active, that the employee is still at the company, or that the domain will accept email to that address today. Address validity changes over time; confidence scores do not update to reflect those changes.
BillionVerify provides what confidence scoring cannot: a real-time SMTP check that confirms whether the specific mailbox will accept a message today, along with catch-all domain detection and role-based inbox identification. Voila Norbert answers "is this the right email address for this person?" β BillionVerify answers "will this email deliver right now?"
What Voila Norbert's confidence score actually means.
| Voila Norbert confidence level | What it means | What it does not mean |
|---|---|---|
| High (90%+) | Pattern matches the most common format for this domain | Mailbox is currently active and accepting email |
| Medium (70β89%) | Pattern likely matches, some uncertainty in the data | Address has not changed since Voila Norbert found it |
| Low (below 70%) | Pattern match is less reliable or signals are weaker | Mailbox exists at all |
| Catch-all domain | Domain accepts all incoming email at server level | Individual mailbox is active or monitored |
The confidence score is a proxy for discovery quality, not a substitute for deliverability testing. Teams that treat a high confidence score as send-ready skip the step that actually confirms whether the mailbox will accept a message. Even a confidence score of 97% can include addresses pointing to employees who left, mailboxes that were deprovisioned, or catch-all domains where individual delivery is unconfirmed.
