What is the Cortex Global Filter?
The Cortex Global Filter allows marketers to remove users from the lifecycle stages (as well as Smart Blast), while allowing those users through into Promo Blast sends.
How To Set Up a Global Filter
Step 1 - Go to Data Management > Smart Segments.
Step 2 - Create a new filter.
Step 3 - Apply to Cortex Settings.
Important! Promo Blast and transactional stages are not affected by the Cortex Global Filter.
Note: Once a filter is chosen as the global filter it will be removed from your list of filters. When it is replaced by a different filter (or removed as the filter) it will re-appear in the list.
