Today, Folio only supports Gmail/G-suite and Outlook Office 365 email accounts (Real Estate & Lending).
Do you know if your relevant email account(s) are powered by G-suite or Office 365? Or are they powered by Go-Daddy or another service?
If you want to use Folio, you will first need a supported email account.
From there you can forward your emails to a connected Folio email address. If you want to display a different email address you can change the email Folio displays from the Profile tab in your account.
