A simple tool to create an URL with Google Analytics UTM campaign parameters. All input will be lowercase appended to the URL. The Google Analytics UTM Campaign URL Builder will also check if the URL already contains parameters. With one click you can add the URL to your clipboard.
Make sure you are strict in using
utm_medium. Otherwise, you will end up with a lot of traffic in the (other) Default Channel Grouping. Your email campaigns should be tagged as
utm_medium. Then they will match for the Email Default Channel Grouping. More information about the Default Channel Grouping definitions and rules can be found here.
Besides this Google Analytics UTM Campaign URL Builder I made a list of handy CRO tools.
