ProtonMail was started by some uber-smart MIT, Stanford and Caltech guys working in Switzerland as a response to the NSA revelations as a way of providing a user-friendly way of using PGP encryption for e-mail. Protonmail operates just like Gmail or Yahoo, but e-mails between and among Protonmail users are what is called "end-to-end" encrypted, meaning that noone apart from you and your intended recipient can read the contents of your e-mail. Even if ProtonMail was forced to hand over your e-mails, they themselves would be unable to read or decrypt the e-mails. Protonmail also provides a nifty mechanism for sending encrypted e-mails to folks that don't use Protonmail (and, for me, is where its use really comes in handy as there is no need to "convert" all your friends and family to benefit to ProtonMail to benefit from the privacy).
I've seen several attempts to try and make PGP work for the masses, and I believe that ProtonMail is the first time that it has been done in a way that can conceivably catch on.
Ideally only encrypted information passes through public email servers, even more ideally your web server sends that information over encrypted TLS connections, but even then your email provider has access to your emails as stored on their mail servers. I think ProtonMail sells itself as an open source (meaning it's very public how they do their encryption and a security expert can review the code for vulnerabilities) and it gives you two accounts -- one for an email account and one for a separate PGP key to your mailbox. Then you can automatically send and receive encrypted PGP emails without all that extra legwork, plus from a cloud-accessible, mobile-friendly website.
