The post-unsubscription page is displayed to users after asked to be unsubscribed. You can customize the default page (Post-unsubscription page) or redirect to a landing page.
For each submission case ("This email address is already unsubscribed." Or "Thank you! Your information has been successfully updated." etc). you can decide whether your recipients are sent to the default page (Post-unsubscription page), or they have to be redirected to a Landing page created on the platform or an external one accessible via URL.
To select the mode, use the drop-down menu located next to each case, as shown in the image.
