Use this interactive demo to learn how to block unwanted sender emails in Zendesk Admin Center.

Quick summary

Blocking emails in Zendesk lets support teams prevent unwanted senders from submitting tickets by adding addresses to the Blocklist in Admin Center. This setting, found under End Users configuration, immediately suspends all future emails from blocklisted addresses once saved.


Steps

  1. On the Admin Center tab, head over to the left-side panel and click 'People'.
  2. Select 'End Users' from the list of options under Configuration.
  3. Enter the sender's email address into the 'Blocklist' input field.
  4. Scroll down to the bottom section of the page and click 'Save Tab' to apply the changes.
  5. After completing these steps, emails from the blocklisted email addresses will be suspended.

📌 Why this matters

Blocking unwanted emails in Zendesk is essential for keeping your support queue clean and preventing spam or abusive senders from creating tickets. By adding addresses to the Zendesk Blocklist under End Users settings, support teams can automatically suspend all incoming emails from specific senders without manual intervention. This feature helps Zendesk administrators maintain a high-quality support experience, reduce agent workload, and enforce communication boundaries at scale. For teams managing high ticket volumes, the email blocking capability is a critical tool for protecting support operations and ensuring only legitimate requests reach agents.
