We have a use case where we have duplicate leads with the same email address that represent different accounts, so we can send emails that are unique for each account to these leads.
So for example, Lead 1 has three separate records for Account A, Account B, and Account C and receives three separate emails with a form for each account. I'm finding that when Lead 1 submits a form, it always updates the record that is associated with the cookie stored on the user's browser, regardless of which account-specific email they clicked on for the form. The form is on a Marketo landing page that is tracked using the mkt_tok parameter.
Is there a way to "override" the cookie so that if the lead submits a form from the email for Account A, it only updates the record for Account A and so forth?
