we asked Salesforce to activate the automatic tagging for our urls in mails for our business units. But after the activation of the feature (utm_medium, utm_source) some of the links coming from a data extension are broken. It seems that the existing string from the data extension which includes already a parameter/query string separator is not correctly "analyzed".
e.g. the url in DE is kind of
When the tagging is applied the email receiver gets the salesforce url which is encoded as
The problem is this url is broken because of the 2 query string separators
The only solution which is unfortunately a manual one is to get these special (problematic) strings working by using AMPscript like this to get a correct URL.
Anyone has an idea where how the automatic tagging will not break the urls int he data extension. The problem is that I cannot ask our user to type everytime AMPscript as they are not aware about this.
