Was this supposed to be in message or campaign model?

    /**
     * @name cc
     * @description receiver(s) of the carbon copy of the message
     * i.e e-mail cc receiver
     * @type {Object}
     * @since 0.1.0
     * @version 1.0.0
     * @instance
     */

      type: [String],
      index: true,
      searchable: true,
      fake: {
        generator: 'internet',
        type: 'email',
      },
    },
