How do I switch a campaign off or on?

• Open Campaigns in the dashboard sidebar.
• Find the campaign, using Search if the list is long.
• Select its On/Off switch. A message confirms Campaign disabled or Campaign enabled.

A campaign that is off is not shown and does not spend. The ad server refreshes its list of campaigns every 10 minutes, so a switch takes effect within about 10 minutes. Delivery resumes when you switch it back on, as long as the campaign is approved and has balance left.
