User E-Mail configuration

Hello, how can I set it up so that various users who have booked a course/event do not receive any notification by email?
I have the email settings under Configuration > General.
But where do I specify that users 2.3.6.8 etc. do not want to receive any emails/notifications?
Data protection in the EU.

Hi Peter

Unfortunately, there is no option to not sending email to only certain users as you want

Hi, wouldn't it be a good improvement if I said that this could be excluded for certain users?
This is required by law in Germany and the EU, so that users can decide this for themselves.
This is regulated by law in our country.
I have already entered a fake email address for users,
but Joomla only allows one email address. If I have already entered a fake email address there, as is currently the case, the provider deactivates the mailbox for sending emails because too many incorrect emails are being sent to incorrect email addresses.
 

EU has so many strange rule. But this is the first time I heard about this request, does that mean these users should not receive email when they register for an account on via Joomla? I haven't seen Joomla has a setting for that as well
