Sanford, thank you for your reply and my apologies in advance for the amateur questions!
We are actually planning on setting up a preference center to replace the current durable unsubscribe-from-everything option. I figure that if we introduce a preference center that is designed to update based on particular lead ID, then it cannot work in conjunction with the email-based durable unsubscribe.
As for the compound dedupe key, this will likely not work for us since as you mentioned, letting them fill in the company name will likely lead to a lot of mismatches due to spelling variables.
If I'm getting this right - if our preference center page is a Marketo-tracked email link such as the current default unsubscribe link, then only the lead ID that the link is unique to will be updated in the database and other leads in the database that may share that same email will not be updated? To follow-up, is every landing page created in the Marketo Design Studio tracked by default or are there additional steps needed to ensure the linked page is tracked?

We have a business use case that requires us to have contacts with the same email address that belong to different accounts. This allows us to send emails that are unique for each account to these contacts. Currently when a contact unsubscribes from our emails, they have to enter their email address in the form and then it unsubscribes each person in Marketo and each contact in Salesforce with that email address (default behavior).
We are looking to build a custom landing page with a form for contacts to choose which type of email they would like to subscribe or unsubscribe from. When they submit the form, we would like to control which account the contact unsubscribes from so they can remain subscribed for some accounts they belong to while unsubscribed from other accounts they belong to. Is there a way to pass the "Person Id" or some other unique identifier through the form/landing page so that only the person in Marketo with that Id gets updated instead of every person in Marketo with that email address?
