What happens when a respondent clicks on an invitation survey link (one that was automatically generated using the [ccaDoPanelLink] keyword), after the sample list that it was sent from has been deleted?
Your respondent(s) will not be able to start the survey. Instead, they'll be forwarded to whatever you've set in the "Internet Options > Final pages > Internal error" page.
Here, I've sent myself an invitation into my survey using the automatic [ccaDoPanelLink].
After the invitation was sent, I deleted my sample list from Supervisor and then clicked the link. I was then automatically forwarded to the plain text I inserted into the "Internet Options > Final pages > Internal error" section.
