Add a folder to mail box in iCloud account
I am wondering if one can add a folder to their icloud mail account. Folders are - Inbox, Drafts, Sent, Junk, Trash, Archive and icloud saved mail. Is there another way to add another folder? Asking for my husband who wants a folder for his work related email that is not his work address.
He wants to send it to himself and have a special folder to put it in.
Thanks!!
