Good cooperation begins with clear instructions that explain what the message should cover, the tone you want, and anything they must avoid. Share examples or reference posts so they understand the direction. After that, give them space to present the idea in their own style, since their natural voice is what their audience trusts. A short check of the draft content before posting helps you confirm that important points are included. Instead of strict rules, use gentle reminders that guide them without limiting their style. Which part of this balance between structure and freedom seems most helpful to you?
