Where the email comes from
We read work emails that a company publishes next to a person's name on its own website: a team page, a leadership page, a contact page. We don't guess addresses for you to try, buy lists of personal emails or read social networks.
Personal addresses (free webmail and the like) are never kept, even when a page prints one.
What we check
The domain: that it exists, receives mail (it has working mail servers), and isn't a disposable-mail or parked domain. We look this up in the domain's public DNS records; we never connect to a mail server to probe an address.
The pattern: how the company builds its addresses (first.last, f.last and so on), learned from the addresses its own pages publish. An address that fits the pattern scores higher; one that doesn't, lower.
Agreement and age: another source with the same address raises the score, a different one lowers it, and an address not seen on its page for months loses points over time.
The score and the line
Every work email and direct line gets one score from 0 to 100 from these checks. Below 70 it is never shown or sold, to anyone. A published address at a domain that receives mail sits at the line; most guesses never reach it.
You see the price before you reveal, and you're charged only when a contact at or above the line is revealed. Revealed once, it is shared with your whole workspace.
When one still bounces
Report it from the contact's menu within 30 days and the credits come back at once. The contact is hidden from everyone straight away, and our team checks it before it can come back.
