I know Hubspot email marketing has its parameter to track, I am tracking my email performance on GA, I know through ad content in GA we can findout Internal Hubspot ID attached to particular emails and measure its performance.
Unfortunatley, I am facing 2 issues
1. Few of my email have been assigned as (not set) may I know why?
2. Internal id is =2 , When i exported emails there is no email with internal ID has 2
Please see the screenshot attached. Any insights would be helpful
