If you ever need to rebuild or create all the emails for a company, you can do this via the company details page.
For example, the format for emails as a company gets bigger might change from firstname@somecompany to firstname_surname@somecompany.
For this to work, you need to have inputted a company's domain and their preferred email template format.
Then, from the Company Options button, select the "Rebuild Email Addresses from Domain and Email Format"
