While expanding my company, I have the obligation to add an extra layer of security. It would be very beneficial to have a user role "editor", that can only create drafts of a campaign, but not send or schedule to send it. A user role "moderator" could revise it and send or schedule to send it. Only the "admin" has full access to settings and account related management.

This structure is well established in CMS systems like Wagtail CMS (https://guide.wagtail.org/en-latest/how-to-guides/manage-users-and-roles/)
