Facebook Custom Audience Destination - Mapping Attributes
I got a concern for mapping attributes of an audience that will be pushed to facebook.
I have an audience that contains users with mobile number and email address. Some have mobile numbers but not an email, some have email but not mobile numbers and some have both.
Question is -> If I select the source fields as email and number, it will only push profiles that contains both source fields?
Should I create separate segments one with numbers and exclude email address, another with email address and exclude mobile numbers and a last one of users that have both?
