To allow reading, you need to encrypt the actual content of the email using a secure email service such as Hushmail, CounterMail, or ProtonMail. Encryption protects your personal emails by obfuscating your messages so they cannot be decrypted unless you explicitly allow someone to read them. If you are using a client-side encryption service like Virtru, even if your mailbox is hacked, the contents of your messages will not be readable. If you are not satisfied with the use of TLS encryption, you can stop email communication and use a secure messaging application.
