Sort mail immediately...preferably over the trash :)
After the Husband brings in the mail with the kiddos, we plop it down on the counter next to the trash/recycling bins and start going through the monstrous pile of (mostly) junk. I shred junk mail and unwanted catalogs and toss both into the recycling bin (writing this reminds me I need to go to this website and cancel certain unwanted catalogs). Anyway, keep only the mail that is personal (yeah!), catalogs and magazines you'll actually take the time to peruse, or important stuff like bills (yuck). The key is doing this each day so you are not junking up your living space with unnecessary clutter. It only takes about 3 minutes so it is certainly manageable.
