Investigator Use
Voila Norbert (voilanorbert.com) is a commercial email finding service that locates professional email addresses based on a person's name and their employer's domain. By entering a full name and company domain, investigators can generate the most likely email address for a specific individual at that organization.
For OSINT investigators working people and corporate investigations, Voila Norbert addresses a common gap: knowing that a person works for a specific organization but not knowing their exact email address. The service uses pattern matching against known organizational email formats (first.last@, flast@, first@) and verifies the generated address against mail server responses to identify the likely valid format.
This capability is particularly valuable for corporate investigations where an investigator needs to contact a subject for an authorized engagement, verify whether a specific person is affiliated with an organization, or cross-reference discovered names against corporate email systems. The ability to convert name + company into email address is a fundamental OSINT pivot.
For due diligence investigations, Voila Norbert can help verify employment claims — if a subject claims to work at a specific company and the generated email address validates successfully, it corroborates the employment assertion. Conversely, if the email fails validation, further verification is warranted.
The service also returns a confidence score with each generated email address, indicating the reliability of the result based on verification evidence. High-confidence results have been verified against the mail server; lower-confidence results are pattern-based only.
Voila Norbert offers a limited number of free lookups before requiring a subscription. For large-scale corporate email enumeration in authorized penetration testing engagements, the paid API provides bulk lookup capability.
Limitations: The service works best for established corporate email domains with consistent naming patterns. Domains using email providers that block SMTP verification, or organizations with non-standard naming conventions, will return less reliable results. Always verify email addresses through additional channels before treating them as confirmed.
Record the name, company domain, generated address, confidence score, and lookup date in investigation documentation.
