I have a subset of folks with a label, let’s say GST.
A portion of the GST subs also have a combination of other labels: GST plus BST TST SST, etc. And of course there are those without the GST label altogether.
I want to send an email newsletter to everyone EXCEPT those tagged GST. In other CRMs, we use suppression lists to do this. We simply say “do not send to those labeled GST. How is this done in Ghost?
