Zendesk Email Notification Security

Learn about security measures for Zendesk outgoing email notifications, including TLS and DKIM.

What security measures are available for Zendesk outgoing email notifications?

While Zendesk outgoing email notifications are not encrypted, Zendesk Support provides opportunistic support for Transport Layer Security (TLS) to secure email exchanges. When TLS is not in use, ESMTP is used instead.

To further enhance security, you can digitally sign your outgoing emails with DKIM or DMARC to prevent spoofing and verify the legitimacy of your emails. This is especially important when setting up an external email domain as a support address. For more details, visit theZendesk support page.
