Go to List and click Categories. You’ll see a list of your current categories.

Next to each category is an Action column with links to Edit or Delete the category.

Click Delete if you want to remove the category. The subscribers that are in this category will not be deleted from the system. 

Click Edit if you want to change the category name, or if you want to change the Active or Private status. 

A category that is Active is ready to use and can have addresses assigned to it. A category that is not Active is not able to be used in as much as addresses can not be added to it. You might create a category that is not Active because you are not yet ready to use the category. Or you might convert an Active category to inactive if you do not want to continue to put subscribers in the category—if you you want the category “cut off” from new members, so to speak. 

Tick the Private checkbox if this is a category that you do not want your subscribers to see on the Subscriber Update page. Subscribers can link to the Subscriber Update page from your emails when you enable the Subscriber Change Link when sending a message. See the KB article for Setting up Subscriber Update Options for more information.
