If you would like to include your campaigns' message subjects when you export One Click Politics signatures to NeonCRM, just add a new Account Custom Field in your NeonCRM Account Settings.
Copy the Account Custom Field's name exactly from the box on your One Click Politics NeonCRM settings page. This field must be named: OCP Message
Your Account Custom Field should have a Display Type of "One-Line Text" and a Data Type of "Text".
For full instructions on how to create your OCP Message Account Custom Field, see: Configuring Custom Fields
