You can also import others' encryption key and read emails. It comes with lots of tools for configuring your email, you will need to choose between two types of email that you would like to use. It lets you pick from the default email client or web email, as well as many options.

Some more tools and features

You can test your email configuration to see if it works before you start sending emails. By default, the application sends the encrypted text as an attachment file and not in the email body.
