In email campaign objects that one could get from https://apidocs.user.com/emails/get-single-email-campaign.html
https://apidocs.user.com/emails/get-all-email-campaigns.html
There is no "utm_campaign" value (nor utm_source, utm_medium, utm_term). It would be highly recommended to add at least "utm_campaign" (while the other are rather "static" for all campaigns) to make easier connection between user.com and google analytics data.
Right now there is no connection unless you use the utm_campaign phrase in the name/description of the campaign.
