Skrapp discovers emails through pattern matching. A correct pattern does not confirm an active mailbox.
Skrapp is an email finder used by SMBs and individual outbound operators to collect email addresses from company domains and LinkedIn profiles. It identifies email patterns from available public data and applies those patterns to resolve contact addresses for targeted companies. The tool is valued for its low friction β small teams can build contact lists quickly without manual research.
Skrapp's email discovery is pattern-based: it determines the most likely email format for a domain and constructs addresses accordingly. This approach is fast and produces plausible results, but it does not verify against the live mail server. An address constructed from the right pattern can still be invalid if the specific mailbox was never provisioned, has been deprovisioned, or if the domain has changed its email configuration since Skrapp last checked.
A BillionVerify verification pass after export adds the SMTP-level check that pattern matching cannot provide β confirming which addresses are currently deliverable before they enter a CRM or campaign. Skrapp handles discovery; BillionVerify handles the question of whether each discovered address will actually accept a message today.
What Skrapp's email discovery actually means.
| Skrapp output signal | What it means | What it does not mean |
|---|---|---|
| Email found | Address pattern matches the most common format for this domain | Mailbox exists and will accept email |
| Domain search result | Pattern applied to domain across multiple contacts | Each individual address is confirmed valid |
| LinkedIn enrichment | Email resolved using LinkedIn profile and employer domain | Address is current as of today |
| Bulk discovery result | Pattern applied to a list of contacts at scale | Accuracy is uniform across all records |
Pattern-based discovery produces useful results at speed β that is its value. But the pattern can be right while the mailbox is wrong. Skrapp cannot know whether an individual mailbox was deprovisioned last week because that information exists only at the mail server level, not in the public data Skrapp uses to build patterns.
The specific risks in a Skrapp export.
| Risk | Source | Impact |
|---|---|---|
| Pattern-correct non-existent mailboxes | Format matches domain convention, but mailbox was never created or was removed | Hard bounce despite plausible pattern |
