After you create a sort rule, it is automatically activated. However, you may deactivate it and then want to activate it again. For example, you may create sort rules you want to apply from time to time. You don't have to delete them and create them again - you can simply deactivate them. Inbox.com uses only active sort rules to organize incoming emails. When applying the sort rules manually to a certain folder, you may use both activated and deactivated sort rules.
To activate a sort rule:
Select the "Settings" tab and "Sort rules" option in the left menu.
Select the sort rule(s) you want to activate and click on the "Activate" button.
To deactivate a sort rule:
