They could send out the information using Whatsapp. Whatsapp encrypts end-to-end. Of course, both the sender and receiver have to use Whatsapp.
In encryption, the problem is usually getting the encryption key from the sender to the receiver. There are ways to do that, for example https negotiates a key between the sender and receiver, so it would be possible to do end-to-end secure mail on a web browser using https.
