I have tested this item ✅ successfully on 6b233c0

Joomla 5.3.4. When Send Mail option is disabled, there is no NEW button in Administrator Panel > Privacy Contests > Requests.
After this PR I see this notification:

Information requests can't be created when sending mail is disabled.

All is clear and informative.
