With reach and frequency buying, you can pause delivery of an active campaign, ad set or ad for up to 30 minutes without having to run a new prediction.

If you're unable to pause your campaign but need to stop it from delivering, you can cancel it instead and still see its performance data.

Steps to pause your reach and frequency campaign, ad set or ad:

1. In Ads Manager, find the active campaign, ad set or ad you'd like to pause.

2. Turn off the campaign, ad set or ad by toggling its on/off switch off. Your selected campaign, ad set or ad will stop delivering while it's turned off.

   If you're pausing an ad within a sequenced ad set, remove the ad from the sequence by dragging and dropping it outside of the sequence and then turning it off. Pausing an ad while it is still within a sequenced ad set will stop subsequent ads from running and disable delivery for the entire ad set.

   Note that turning an ad set off for more than 30 minutes will require a new reach & frequency prediction. You'll need to accept the new prediction in order to turn the ad set back on.

3. Turn your campaign, ad set or ad back on by toggling the back on.

Once you have turned the campaign, ad set or ad back on, it will continue delivering.
