The term "landing pages" refers to a feature that allows you to design hosted web pages. These Landing Pages can be used in emails as a redirect for a link or they can be used in forms to redirect the subscriber to another page.
For example, you may create a Landing Page as a custom unsubscribe page, a temporary page for an email-only deal, or a custom subscribe page that sets expectations for the new subscriber.
The Landing Page builder can be found in the Assets module.
Please note that this feature is only available upon request for B2B licence clients.
