Sometimes it can be necessary to mark a ticket as spam in Zendesk. There are two ways to do it:
Recommended way: click the arrow in the right part of a ticket and select Mark as spam:
Marking a ticket as spam using this method suspends the end-user, and they won't be able to submit tickets or access our Service Desk anymore. If you are unsure this measure should be applied, use the alternative method below.
Alternative method: open the ticket and select Spam macro in the list of macros. It will add a tag and solve the ticket once applied. The CSAT survey won't be sent for tickets with this tag.
