How can categories be filtered out of the Summary email?

Hi
How can categories be filtered out of the Summary email?

If you would like to filter out certain categories from appearing in the Summary email, you can do so by going to the “Preferences” section of your user account, and then selecting the “Categories” tab.

From there, you should be able to select which categories you would like to ignore on the “Muted” section.

Cheers.
