Does Mark act on its own, or confirm first?
Mark always confirms first. When you ask for something that changes your account, Mark shows a summary of the exact change and applies it only after you approve.
What needs approval
Approval is required for anything that writes to your account: creating campaigns, ad sets, and ads, and edits like changing budgets, schedules, audiences, or turning things on or off.
What does not
Read-only actions do not need approval, because they change nothing. Asking a question, pulling insights, or getting a performance summary all happen instantly.
Why it matters
Together with new campaigns always being created paused, confirm-first means Mark can never spend your money or push a live change without you. You stay in control at every step, which is exactly the point.
