so, when I hover over our unsubscribe link in an email I see something similar or maybe the same as what you're talking about with the 1&mkt_tok does this mean it's tracking and I don't need a smart campaign like I posted the pic of originally?
I've used these smart campaigns in the past in order to track which campaigns are responsible for an unsubscribe. It's purely to show performance of a specific campaign at a high level. This is just changing the program status so that it doesn't show the person as being a success from say, opening or clicking, because their ultimate action was unsubscribe, so it changes their status.
I would also guess the campaign isn't synced 1:1 with Salesforce, so the program status is being manually changed in Salesforce as well. It's for reporting purposes.
Hope that helps!
