The url has still the utm variables of sendgrid's newsletter. Therefore all these visits here (let's say 3-7k) will be attributed to sendgrid.com/email
Is there a way as site owner to avoid this? Would automatic redirect to the same url without utm params still add goals to that source?
You get number of email clicks from separate metric, plus you get total reach from Google Analytics - so that you know total impact of your mailing (or any other channel you're tracking), including reshares.
But people tend to copypaste and share this url to facebook, twitter or hackernews. Which completely skews your GA information.
Therefore my original question: is it possible to avoid this.
