Powerful, but not like, too powerful.

No send accessModels and API keys cannot send a campaign or delete contacts. Only you can do that.
Drafts open in your editorEverything the model writes lands in the campaign editor, easy to change by hand before it goes out.
You approve every sendA person reads the issue and presses the button. Your list never hears from an unsupervised machine.
