How do I delete campaigns, ad sets, or ads in bulk, and can I undo it?

Select the items, open Bulk edits, and click Delete. A confirmation window shows what will be deleted. Review it carefully, then click Delete to confirm. The list updates immediately, and if any item fails, a notice tells you which ones. Heads up: deletion happens directly in Meta and cannot be undone, neither in Ads Editor nor in Meta Ads Manager. If you only want to stop delivery while keeping the history, use Pause instead of Delete. Tip: turn on the Filter selected filter before deleting to check exactly what is selected.
