How to Setup a Proofing Process Distribution Group

Log in to your admin homepage and expand "Communications" application group. Then click on "Distribution Groups".
Click "New" at the top to start a new distribution group.
Enter a name for your distribution group. In this example I am naming it "Proofing Process" since I will be using this distribution group every time I need to send a proof. Make sure to select Member Communication for the message category. Click Create
You should land on the "Select Recipients" tab of the distribution group. Change the toggle to "On" for Miscellaneous Recipients Click the arrow to the right of the Miscellaneous Recipients label In the text area that appears on the right enter as many email addresses as you need separated by commas
Click on the "General" tab, then check the box for "Active" Click Save
Your distribution group is ready for use. The next time you are getting ready to send a proof and you are on the "Select Recipients" tab just click "Use Distribution Group".
Select the correct distribution group from the list Click "Next"

You're all set! Now you don't have to manually copy/paste everyone's email address every time you send a proof, just select the distribution group and you're done!
