At the momenti this is my link: <a data-nl-landingpage="VAL_Unsub_FR" data-nl-landingpagedynamicservice="false" data-nl-landingpagelabel="VAL Unsubscription FR" data-nl-type="landingPage" href="#" id="a15840993430068" style="display: inline-block; font-family: Arial, Helvetica, sans-serif; font-si...

I need to create unsubscribe link to insert in my html email (it should be dynamic for language) and I should see the unsubsription in the report area.

I inserted "&&" but code editor converted in "&amp;&amp;" (using "show source")   

By entering your condition seems the HTML editor doesn't read it correctly: and the mail is not sent. 

ok @ParthaSarathy , it's working using:<a href="<%@ include fragment='MirrorPageUrl' %>" _label="Mirror page" _type="mirrorPage">Click here for Browser version</a>but when i click and go to web version, this link is still visible. It should be not visible, how can i hide in web version?

Attach the final HTML I'm uploading in my campain using the legacy edfitor, but the email seems to have some error, the preview does not show up and if I do send proof+rendering html it does not arrive.when I remove the mirror line everything works again. Do you any suggestion?  

And automatically Adobe Campaign will hide this cta in web version?
