Data Filter excluding Subscribers in Contact Builder

Knowledge Article Number 000220896
Description
The cause lies with the way SQL interprets NULL values when excluding data. A filter is set up to exclude a certain value, like "exclude all subscribers whose city is Chicago," but if any subscribers have a NULL value in the "City" field, those records are excluded. The report then contains inaccurate results.
Resolution  

How to resolve the issue
 

  • Remove any NULL values from fields to get the most accurate results.
  • A work around would be to filter just the data you don't want and to use it as an exclusion list.
