When you’re distributing a campaign through email, you can choose the specific list you’d like your campaign to go to. Your campaigns will be automatically set to send to All, but you can click the Include Lists drop-down menu and choose from there. You can add multiple specific lists to further customize who receives the campaign.
Conversely, if you’d like to send to all of your email lists except for a few specific ones, select Exclude A List. You can customize which lists to exclude from there.
