Thanks Florent and Amit! florentlb,For 'Authorize unidentified visitor'
and 'Authorize visitor identification via URL parameters(AES encryption
key)', Can you please share some specific use case that can be achieved
with those 2 above features? It will be very interesting to know. I went
through the documentation but not clear on use cases.If I uncheck
'Authorize unidentified visitor' in landing page properties and publish
it: Can the landing page link only be opened by the email recipient?
wha...
