How do I connect my mailbox?

Go to Settings → Email and type the email address your invoices arrive at. TruDues works out who provides that email and shows you the right steps: Sign in with Microsoft for Outlook and Microsoft 365, a short set of steps for an app password (Gmail, iCloud, Yahoo, AOL), or just your email password for most business email hosts.
