Fastmail adds a header to every email with any sort of unsubscribe link. I send those to their own folder (except ones I add to contacts). My main inbox is basically 100% things I expect to see there at this point. I view the mailing list stuff less regularly and unsubscribe anything I don’t want there. If it keeps coming (or if the unsubscribe process requires more faff than doing it through my mail client) I delete it and mark as spam. In 30 years I don’t think I’ve ever felt more in control of my email.
