Which email configuration is essential in preventing spam inside Zendesk?

Domain whitelisting is a crucial email configuration within Zendesk that helps to prevent spam by allowing only specific email domains to send messages to your support tickets. When an organization implements domain whitelisting, it creates a controlled environment where only trusted domains can communicate with the support system. This ensures that any email interactions are more likely to be legitimate inquiries, as they originate from recognized sources.

In contrast, pop-up notifications, chat routing, and email auto-responses do not directly address spam issues. Pop-up notifications are primarily intended for user alerts and updates within the platform, while chat routing focuses on directing incoming chat requests to the appropriate agents. Email auto-responses, on the other hand, serve as automatic replies to incoming emails rather than filtering or preventing unwanted messages. Therefore, domain whitelisting stands out as the most effective means of managing and mitigating spam within the Zendesk environment.
