Exclude specific user lists from email recipients

We regularly send reminder emails to users of one of our workspaces. Since these reminder messages are sent quite often, some users prefer not to receive them. Therefore, we’ve created two user lists: "allowed to email" and "not allowed to email." This setup works in principle, but before every mailing, we have to check that all users are on the "allowed to email" list. Registration to our workspace is open to everyone.

It would be great if, when sending an email, there was a straightforward option to exclude users from a specific list of recipients. This way, we could send emails to everyone except those who are explicitly added to the "not allowed to email" list, saving us time and manpower daily 💪
