5. Since we are looking for all company email addresses that are blank, you will want to leave the right side of the filter interface blank.This will allow you to search for all client records where the email address is, in fact, blank.
6. If you'd like to search client records for centers other than, or in addition to, the current active center, include the Centers filter and choose "All permitted, active centers"

7. If you'd like to save this filter, click the Save button and enter a descriptive name for it in the Name field. For more information on managing saved filters, view the FAQ titled Can I save my filter for future use or to share it with other Neoserra users?.

   If you would simply like to see your results, click the Apply button.

The capabilities of filters are endless and are available for most record types. For example, you could create a similar filter of contact records to identify all contacts without an email address.
