On mail, start calling all of the people that send you junk catalogs and other junk mail and ask to be taken off of their mailing lists. If there's no phone numbers on the junk mail, just Google their name XXX customer service and you'll almost always find them.
A lot of junk mail and catalogs are printed 4 - 6 months in advance and then delivered to the post office palletized with each piece in zip code sequence so the post office doesn't have to do any sorting, just ship them to the correct post office already in sequence for the delivering postal carrier. So get started on canceling the junk now.
Get everything else you can sent electronically that you can and you'll find that you really will have very little mail to deal with.
