Review on Sbwave by Marco Habersham

The best thing about this software it's easy to use, you don't need any technical knowledge or experience in order to set up your account. You can also send encrypted emails without having access to an internet connection at all times. It doesn't provide end-to-end protection but I believe they are working hard towards providing such kind of security feature as well. They have not implemented yet so far. We're using sboom which we've found very good when sending secure communications through our business partners around the world.
