In and Out Boxes Mail

I certainly strive to be more organized.  It's a full-time job and the more I take on and do the harder it is to achieve.  So, I am by no means ultra organized or perfect.  But, I believe that I might have a solution for keeping the stacks of incoming mail that I have presorted through to attend to from being here there and everywhere in piles.

Granted, this idea hasn't been put into play, as of yet, as the basement library project is still in process.  I do already have the materials though; which consist of Pottery Barn office rail system with a couple of the white hanging containers (for desk area).  Plus, I have one red, Swedish metal post box and one very similar embossed white, Swedish metal post box.

My idea is to place the Swedish post boxes at the top of the basement stairwell as my paperwork and mail in and out boxes.  Neat appearance, sealed by a hinged cover and color coded for in or out.

Any thoughts or opinions, such as a better method or what works well for you?

Note:  If interested in purchasing - I did not purchase the mail boxes from the business I am providing the hyperlink to and when I purchased my items, I paid considerably less.  The red box, shown above that they sell is exactly the same, but was purchased locally some time back.  The white box is from Restoration Hardware and is no longer available from their store.
