What is the unsubscribe page for?

It is a confirmation page that is displayed when the unsubscribe link is clicked in an email campaign.

Every email campaign you send must contain an unsubscribe link so recipients can opt-out of your mailing list with a single click. The unsubscribe page confirms that they have been successfully unsubscribed from the list.

All of your lists use our generic unsubscribe page by default, but you can optionally set up your own custom unsubscribe page to match the look and feel of your website.
