Filter to pull in email address is "blank"

[Tara_Rowe]

I am trying to pull out all email addresses that are blank in a SmartList but am not having such luck.

Is there a way to pull out the blank addresses? I have tried adding in NULL or email is invalid but it is not pulling the "blanks"

You want to use the "Is Empty" operator in the filter.  That should return the results you're looking for.

NULL is only used for writing an EMPTY to the field.
