The free version of ProtonMail supports 500 MB of email storage and limits usage to 150 messages per day. With a no-log email service like ProtonMail, emails can't be traced back to you. ProtonMail also doesn't keep your IP address information. The decryption happens when you log in, which means the service doesn't have a means of decrypting emails without your password or a recovery account on file. ProtonMail is so secure that it can't recover your emails if you forget your password. Nobody can decrypt ProtonMail messages without your unique password-not even employees at ProtonMail, their ISP, your ISP, or the government. The most important feature when talking about any encrypted email service is whether or not other people can access your messages, and the answer is a solid no when it comes to ProtonMail, as it features end-to-end encryption. It works from any computer through the ProtonMail website and also through Android and iOS mobile apps. ProtonMail is a free, open-source, encrypted email provider based in Switzerland.
