Smart list filter with profiles without mail
Hellou community!
I have a problem when I create a smart list. Through an integration I have with Salesforce, I receive emails that are empty, so I want to create a flow that eliminates people who have empty emails.
When I create a smart list or in the same smart campaign I put the "Email" with the attribute "It is empty" and I go to review the pages of people I see that if it brings people who do not actually have an email. But when I go to the next pages, I see that it brings me people who do have email. I don't know if it could be an error in the instance or in the list. But in the instance we have, the only field that this procedure for email is called "Email" which is the field that I bring to validate that the emails are not empty.
I don't know how I can make a filter and make it exact, where it only brings me the people who really don't have an email so I can delete them from Marketo.
I appreciate your help
