How the email format finder works
Search a company domain to see the most likely business email format, such as firstname.lastname, flastname, firstname, or firstname_lastname. Seeded entries come from the EmailCheq repository, while searched domains can be added as people use the tool.
A suggested company email format is a starting point, not a guarantee that a mailbox exists. Use the generated pattern with the email permutator, then validate the strongest address before adding it to an outreach list.

Email format questions
What is a company email format?
It is the pattern a company commonly uses for employee email addresses, such as jane.doe@company.com or jdoe@company.com.
Can one company use more than one format?
Yes. Teams, aliases, acquisitions, and older accounts can use different patterns, so validation is still important.
