there was a program called "here lies mail" or something like that, that i installed a while ago. it placed a number in the menubar white the amount of unread mail.
like you, i always miss email, since my dock is hidden. but personally, i do not like a busy menubar.
so i went in search of another way to not miss email.
one way i found was to make a simple rule in mail.
i called it "bounce mail icon"
if any of the following conditions are met:
Every Message
Perform the following actions:
Bounce Icon in Dock
that works amazingly. for every single email you get the mail icon will bounce. it will bounce until you click on it.
