Mac Mail

My Mac Mail App gets the e-mails but it doesn't show me notifications at the bottom (the one with red big circle with white text in it: notifying 1 for one e-mail etc) it doesn't show that unless i go to "Preferences > General > Dock unread count (selected default is "Inbox Only" but if I choose that i don't get notification even though the e-mail does get through like I said). Now if I choose: Preferences > General > Dock unread count tab > All Mailbox Only. But it shows numbers notification at the bottom even though i've checked my e-mail yet it still has (ex. 3 e-mail) showing. I really hope I'm making sense. This is really bothering me. I have three e-mail accounts: iCloud, gmail and hotmail only. if any one needs pictures of what I'm talking about, let me know.
