To be honest, Ray, I figured a seasoned emailer like you would have his own efficient system for keeping things organized ! If it ain't broke, don't fix it.
My own email activity these days is quite minimal, and with the recent passing of a friend to whom I did half of my emailing, I'm guessing that things will crawl to a virtual halt, except for getting online shopping receipts, 'forwards' from aunt so-and-so (featuring political commentary/humor or cute videos of the monkey befriending the kitten, etc.) and a bi-monthly check-in with a friend who lives in Wisconsin. (Nosiree, my email needs just ain't what they used to be. But that doesn't mean I'll give up my interest in reading about the lastest features & services.
) Anyway, maybe the archiving & searching method mentioned in the article would actually work for me.
