Cookie Across 2 Domains

Hi everybody,


I want to implement a cookie to store the values of the UTMs when a lead hits our website from our paid campaigns. A cookie will help me preserve the value of those utms even if a lead doesn't convert right away.  I'll set up all my forms so that when the lead comes back and fills out a form,  the hidden fields in my form will pull the data from the cookie and store them in our database.


The problem I'm facing right now is that I have marketo forms embedded in both my corporate website ( and in maketo landing pages ( which have different domains. My web team let me know that cookies are domain-specific. So if the cookie is created when a lead visits my website (, that cookie won't be readable from a form living in a marketo landing page ( and viceversa.


Has any of you faced this situation? How did you solve it?


Thanks in advance for your help!
