I really love the comparison between the CTA/Pitch of Zumbox compared to EarthClassMail.com. EarthClassMail is also not free, and also is far to involved to get me to be excited and sign up.
Zumbox and ECM are very different.
With ECM, you purchase a mailbox and get a real postal address in many destinations (USA and others). With every letter that is sent to your address - you get an email notification with a scan of the envelope. You can instruct ECM open and scan the content of your letter or you can instruct them to recycle it instead. It's a very convenient service because it saves you the need to handle paper mail.
Zumbox offer a new marketing approach. They try to get people to sign up and try to get marketers to send mail to those who registered. I guess their ultimate goal is to render the USPS worthless.
