I have enabled WAC and use of additional parameters for UTM tagging in emails. But what I would want to do is use [__AdditionalEmailAttribute3] inside email links so that I can make its value dynamic. I would want its value to be different in each link. So , the UTM tag would be the same for all links except the last attribute which would be different. How can this be achieved . Any help would be appreciated . Thank you.
The __AdditionalEmailAttribute3 is a global parameter, which will be same for all your links. Instead, I will suggest you to update the URL string in Setup > Data Management > Parameter Manager by adding
%%linkname%%, like this:
This will take the content from alias:
<a href="https://salesforce.stackexchange.com/" alias="StackExchange">Hello</a> showing StackExchange in this case.
Keep in mind, that it will not populate in cases where Alias is set programatically, e.g.:
<a href="https://salesforce.stackexchange.com/" alias="%%=v(@myAlias)=%%">Hello</a>
