Hi Christina,
I ran a few tests to assess how this is really working. Here are my findings
1/ The setting in the admin only have effect on the unsubscribe link if:
- You are using unsubscribe default settings (admin -> email)
- your email template has NO {{system.unsubscribeLink}} token
In any other case, the settings in admin->sales insight has NO effect on the unsub link.
2/ the setting also has a second behavior: it enables to send an email to an unsubscribed lead or not. The unsub lead will only be sent the email if the admin setting is set to "Hide Unsubscribe Footer" for the appropriate email category.
IMHO, the way the admin setting is designed is confusing. We should on one end set the behavior of the unsub footer and SEPARATELY define whether or not we authorize sending any of these 3 types of emails to an unsubscribed lead. All the more so as most of the templates at hand with the email editor v2 have some unsub footer modules.
