CRM - Email Campaigns - CC's everyone and More

Working with the CRM, the CC send to “ALL” listed in the email group that is specified in the email campaign. On a 4 step (drip) campaign, it sends the marketing list (email group) to everyone receiving an email every time a step fires.

It literally sent the entire marketing list to competitors. Oopsy. Thoughts?
