Email Traffic problem
I have noticed that throughout 2015, email traffic to our site has decreased considerably, however when I look at our email campaign reports generated from Dotmailer, the click through volume has increased. This seems very contradictory and as a GA newbie I wondered if anyone had any ideas why this might be or things I could check?
Re: Email Traffic problem
Source and medium are both mandatory, so if source is missing then you also won't get the medium. For email, utm_medium must exactly match 'email'.
Best guess is that your email marketing department isn't diligently setting the tracking parameters.
