How can you create a Restricted/Closed Zendesk Support Instance?

Creating a Restricted or Closed Zendesk Support Instance is effectively achieved by white-listing or black-listing specific email domains. This functionality allows administrators to control who can submit tickets to their support system, thereby restricting access to only certain users or organizations.

By whitelisting, only users from approved domains can create tickets, which is essential for teams that need to limit support to specific clients or partners. Conversely, blacklisting prevents users from specified domains from gaining access, which can be useful for excluding unwanted or spam submissions.

The other options do not provide a means of controlling access to the support instance. Adding more agents or changing ticket priority settings impacts operational capacity and workflow rather than access, and increasing the number of tickets allowed does not influence who can submit them. Therefore, whitelisting or blacklisting email domains is the most effective method for creating a Restricted or Closed Zendesk Support Instance.
