Email Discovery — a name and a company, one address

Two fields: full name and domain. Press Find. That is the whole interface, and it is the right amount of interface.

How it works underneath, and why that matters to you

Corporate email is not random. It is generated by a rule, and a handful of rules cover nearly everything:

• first.last@company.com — most common in mid-market and enterprise
• first@company.com — startups
• flast@company.com — very common in US enterprise and finance

So the tool derives candidates from the pattern and then verifies them against the mail server. That verification step is what separates a lookup from a guess — and it is why you should care whether a tool does it.

The case where it genuinely cannot answer

A catch-all domain accepts mail for every address, real or not. Ask it whether asdfgh@bigcompany.com exists and it says yes. Verification therefore proves nothing there, and catch-alls are disproportionately common at exactly the large companies you most want to reach.

An honest tool reports this as unknown. A tool that reports it as valid is not more accurate, it is less truthful — and when a vendor advertises 98% accuracy, this is usually where the number comes from.

Bulk

The companion screen takes a CSV of first name, last name, company and runs the same thing at volume. Same rules, same caveats.
