How do I turn off briefs?

Open your project, go to step 4 Monitoring, and change the Send: frequency to Off. The project stays in your Dashboard, but no more Competitive Briefs will be sent for it.

To change frequency rather than turn briefs off entirely, for example from weekly to monthly, use the same control. See how often are briefs sent?.

If you want to stop briefs for one specific recipient instead of the whole project, open the recipient list in step 4 Monitoring and remove the address. See who gets the brief emails?.
