How Zendesk Prevents Mail Loops

Discover the methods Zendesk uses to prevent mail loops, including notification suppression and update limitations.

How does Zendesk prevent mail loops?

Zendesk employs several strategies to prevent mail loops, though not all loops can be stopped. Measures include suppressing automated notifications for Zendesk-to-Zendesk emails, maintaining a partner addresses list, using unique support addresses, and not creating tickets from bulk or no-reply addresses. Additionally, Zendesk limits the number of updates a user can make in an hour to prevent loops from escalating.
