Key points about the opt-out mechanism:

  • Recipients can typically find an opt-out link or button at the bottom of marketing emails.
  • Clicking on the opt-out link directs recipients to an unsubscribe page.
  • On the unsubscribe page, recipients can confirm their decision to opt-out or adjust their email preferences.
  • Opting out is usually a straightforward process that involves entering an email address or selecting preferences from a list.
  • Once recipients opt-out, they should no longer receive future emails from that sender or organization.
