How to suppress an embedded form for known visitors?

[Milena]

Hi everyone, sorry I could not find an answer to this. 

We are using embedded Marketo forms in our website that runs on Wordpress. 

When I send emails to known people, I want them to click a link and get to the asset in our web site (i.e., not to a standalone PDF), I want them to land on an asset landing page but not see the form. How can I achieve that? I understand that my web team needs to suppress it on the web server side - is that right? (Ideally, I would love to be able to avoid modifying the URLs in emails to indicate that the click comes from a Marketo-sent email - I found some recommendation for that approach but I'd prefer to not have to do that if possible). Thank you!
