Criptext is an email app that stands out from other messaging services because of its high security. In addition to having a minimalist and elegant interface, it guarantees its users that all emails sent and received to this server will be protected and encrypted to preserve the user's privacy at all costs. Of course, to get started with the app, you'll first need to create a Criptext email account. Creating your account is completely free, and it takes just over two minutes to do so. It's important, however, to take the time to choose a good security key and recovery email. After creating your Criptext account, you'll receive 500 MB of free storage, which you can increase by making a small donation to its developers. As expected, the app has all the features you might want from a good email client, plus a few extra related specifically to security. For example, you can send password-protected emails or send emails that self-destruct after a certain period of time. WARNING: Before you use this mail, you need to be sure what you need this mail for? If you need cybersecurity and privacy, I strongly advise you not to use this email. Right now criptex is using some weird js scripts, collaborating with some non-foss corporation, opposing foss ideas. Also the standard client is distributed exclusively in play store, has google trackers, libraries, proprietary services. If you are looking for an alternative, confidential mail, in that case I can highly recommend you to read this list: https://m.13f0.net/shadow_wiki/email.xhtml.
