Question
Are outgoing emails in Zendesk encrypted to end-users?
Answer
Zendesk Support has opportunistic support for Transport Layer Security (TLS), a cryptographic protocol for email exchanges, that is enabled automatically on every account. Emails are encrypted whenever an inbox provider supports encrypted messages. If the receiving server does not accept encryption, ESMTP is used instead.

@zendeskSupport - has this answered changed since the new EU laws (GDPR) have been implemented?
I would also like to learn more about this.
Hi Nedula and Helle -
You can visit our EU Data Protection site to learn about all of the changes and compliance related features and functionality. If you have questions that are unanswered by that site, please email them to privacy@zendesk.com for further assistance.
A direct link to the articles about email encryption would have been nice. It is almost impossible to find anything on that site. I can't find where I can search on that site. And sending an email to legal demands that you have a lot of patience.
Maybe I just don't understand the EU data protection site.
I've updated the wording to be more clear.

In short -- They are likely encrypted if the receiving/sending servers are supporting TLS.
Thanks Ryan W
Just to be clear. What about incoming mails?
If the customer's server is supporting TLS and the customer is sending an email to our Zendesk is this mail then encrypted with TLS ?
As I understand- then both servers are supporting TLS
Hi Helle!
That is correct for incoming emails as well. The emails are encrypted via TLS, as described here.
