Email Insights Does Not Display Any Metrics for Specific Program
Issue
Email Insights does not display any data or metrics for a specific program when the emails in the program are operational.
Solution
Operational emails are hidden by default, so no data or metrics will be shown in Email Insights unless 'Operational Emails' are included
"Does Email Insights support Operational emails?
Yes. By default, Operational emails are hidden from view and querying. However, you may change this setting under the Personal Settings panel."
