1. If you do not have at least one marketing email set up in your account you will not be able to save your email campaigns  outside of draft mode. To remedy this, you need to go to your settings and add one or more marketing emails.
   
   
2. If you leave your email campaign while editing and do not save your changes. It will be saved in draft mode. To fix this, click on the pencil icon to enter into the campaign edit mode and hit the save button. Upon saving your email campaign will be removed from the draft status.
