Email link tracking in Adobe Dynamic Tag Manager and GA

I need to ensure that the custom email link tracking dimensions are setup in DTM and Google Analytics for example: It’s also important to make sure ‘set’ method called before ‘send’, otherwise it wont be captured by Google Analytics. 1) For «uid» and «mh» variables following code should be fired: Where {uid} and {mh} - values of «uid» and «mh» GET variables. It’s highly important to send these variables first into Google Analytics. 2) For «exn», «mn» and «ct» variables following code should be fired: Where {exn}, {mn} and {ct} - values of relevant GET variables. For instance, if someone click on a link above this code will be executed: ga('set', 'dimension1', {uid}); ga('set', 'dimension2', {mh});
