Great idea! I really wanted to use this...but then I dug into how it worked. You have to use their Credo cryptocurrency to get your email through / you receive Credo when someone pays. Which no one has and no one should have. They probably take a fee on every payment. Once you get Credo you probably want to exchange it for USD or another crypto that is more broadly used and accepted at other merchants. How do you do that? Through their exchange which they take a .25% fee to buy sell. So they double dip on a micropayment of a few cents. I wonder which part of this enterprise will survive in the long run...the email service or the exchange or neither once the ICO money runs out
