3. StartMail .

The interface is simple and uncluttered, the entire service is based on a web interface rather than on applications for mobile or desktop computers.
E-mail messages can be encrypted in several ways, either by questions and answers, where it is a requirement of the recipient that it will respond to a question before the content is decrypted (a password can also be provided instead), or by the sharing of encryption key PGP.

What could be more practical when you need to send detailed information, or who were not supposed to be shared.
There is also a real-time tracking that allows you to see if your email was received and read.
Note that unlike other services, Criptext does not record any message on its servers, it merely acts as a medium for the transmission between your device and the recipient.
All your communications are stored locally on your PC, your smartphone or tablet, which also means that there is an end to end encryption and that your communications may not be read by Criptext.
The encryption operates with the open source protocol, Signal Protocol for better protection of your privacy and prevents third-party services to access them.
Add to this that each email has its own key, so even if it is acquired by a hacker, this will not be able to read the message in question, and not the other.
One thing to keep in mind is that you need to have, at any time, at least one device connected to the Criptext (you can have up to 10) otherwise you lose all your communications.
