We have verified emails, scraped emails and pattern guessed emails.
When you enter in a name and website, we'll return a verified result for 1 in 4 or 5 queries. We'll also then return pattern matched and scraped emails for some of the other queries so you may get a result 50% of the time.
Why can't you verify every email?
Some websites don't allow verification.
Some websites are down or dead.
The email may be in a weird format like firstname.lastname@example.org
