This is a hypothetical / architectural question, as I haven't come across the need yet.
Let's assume a very simple example: I want to block out certain domains from receiving our emails.
I could use a simple:
Domain(emailaddr) != "google.com" OR Domain(emailaddr) != "microsoft.com"
Now, this is fine - but imagine i want to grow the list over time, can i store the script in a content block, and then simply use:
This would essentially allow me to scale the exclusion script, making it easier to manage. It would also, introduce a "one fails, all fails" type of build - but for some scenarios and with proper development practices, it might be a good thing.
However - is it feasible?
