Proton Mail anonymous mailbox, effectively protect personal privacy (not a temporary mailbox)
Proton was born in Switzerland in 2014 when a group of scientists who met at CERN (European Organization for Nuclear Research) decided to build a better Internet where privacy is the default setting. Anyone can apply for a free Proton anonymous email to protect your personal privacy. You can use the anonymous email to register other applications and surf the Internet better! The whole world is working hard to protect personal privacy issues. Proton is awesome!
