Having a dedicated spot near the entrance of your home for processing your snail mail can definitely reduce clutter... but shredders, rubbish recycling bins aren't really great decor. Unclutterer offers a neat DIY solution for a mail sorting system.
Basically, underneath a wall message board or communication station, you hide your shredder, and rubbish and recycling bin in a closed storage bin (with a hole drilled in the back for the shredder's power cord). A toy chest (or other bench with storage space) can be an ideal container because of its size.
You'll have one spot to deal with all your mail before it invades your home, hidden in plain sight. Photo remixed from originals by Unclutterer
