How long are customer satisfaction survey links valid?

Customer satisfaction survey links remain valid until the ticket is closed. This means that even after a ticket is resolved, the survey remains accessible to the customer until the final closure of the ticket. This design allows customers some time to provide feedback on their service experience, which can be valuable for continuous improvement efforts within the organization.

In contrast, survey links would not be valid until just the ticket is open, as this could limit the customer's opportunity to respond after a resolution. Also, tying the survey link's validity to the customer's action of responding would present challenges, as it could lead to scenarios where feedback is not collected effectively. The option mentioning validity for a fixed duration of 30 days after creation might be applicable in some systems, but Zendesk guidelines specifically bind the survey's accessibility to the ticket's status, which is closed in this case.
