Is There a Barrier to Entry?

i was really quite shocked to realize just how much the actual volume of email has increased over the past two years. It's a frustrating problem. And what i'm trying to do is, through a variety of smart mail boxes and filters, is divided all up into four categories. So in theory, i should be working from like v i ps to contact non tax to the junk and clear the boxes in that order. But even there, it's super frustrating, caus lik o, i want invoices from paypal to show up in the v ip category, but there's no good way to try to filter it so that you only get some of their messages.
