What is the difference between List Unsubscribe Header and List Unsubscribe Post Header
Hi.
I want to ask you some questions.
1.What is the difference between List Unsubscribe Header and List Unsubscribe Post Header?
2.As shown in below, in the Email Unsubscribe report, two different source attributes can be seen: List Unsubscribe Header and List Unsubscribe Post Header.
Different contacts unsubscribe from the same campaign email within the same email group.
But why is displaying different sources in the report? What caused this result?what is the describe of the sources(List Unsubscribe Header and List Unsubscribe Post Header)?
Thanks
