I also scraped the "auto" parameter which automatically submits the unsubscription form when the link is clicked in a campaign email. Instead, I introduced the
unsubscription options ONE_STEP, ONE_STEP_WITH_FORM, TWO_STEP, TWO_STEP_WITH_FORM. The options without "_WITH_FORM" shall behave like when called with "auto".
This functionality is to come. Currently it behaves as ONE_STEP_WITH_FORM.
