The Actions Center then notifies the booking server through `SetMarketingPreference`. If a user opts in, `user_to_receive_marketing` is set to `true`; if they opt out, it's `false`. No selection means no request is sent, retaining the previous status. Users can unsubscribe via an email link, managed outside the Actions Center. Double opt-in may be required, with subscription only confirmed after the user completes an email confirmation.\n"]]
