Do Black Listed people get automatically excluded from emails (like opt outs) or is there an additional rule that needs to be set up? Also, do people from EXCL lists get excluded or again needs to be excluded by rules?
Blacklisted people are excluded from the emails, For the EXCL list, you need to set certain rules to exclude them.
AFAIK, and to be more accurate:
Also, do people from EXCL lists get excluded or again needs to be excluded by rules?
P.S. You shouldn't use abbreviations like this that don't have an established definition. The four capital letters "EXCL" aren't special, they may merely be part of a personal naming convention. And, as Ronen notes, if you want them to be "exclusion lists" that's only via rules you create. You can have a list that starts with "EXCL" and have it be an inclusion list.
