SaneBox does charge for its services, with monthly rates starting at about $2 and moving up to $20 and beyond, depending on what you need. The company does offer a 14-day free trial. I tried out the service that way and quickly found myself completely dependent on it.
As I say, I'm not using everything SaneBox can do, but what I do use has made my inbox way more manageable than it was before. I no longer have to spend a bunch of time wading through irrelevant emails in my inbox to find the ones I want. Rather, Sanebox weeds out the less essential stuff for me, so I can focus on the messages I need to see and deal with the rest later. If you find yourself drowning in email--and who isn't?--I say give SaneBox a look.
