Thanks for reply but is not clear what i have to do probably.
I have some users in the list test (green)
But, as you can see, others users are in multiple list.
I have to send a newsletter to users of all list except "test" but i have to NOT send email also to these users present ALSO in list "test". In other way i have to not send mail to the users in red circle
even if they are in the other lists and i'm sending email to other list
It's more clear now?
Sorry for trouble.
