@Aubrey,
As long as your subscription center is clear on how to unsubscribe from all emails and the verbiage in your email says that unsubscribe is possible through the link, you will be US compliant.
Are you using the Global Unsubscribe text found in Admin? You can use this feature to ensure the unsubscribe page is sent with every email.
- if so, the out-of-box implementation sends records to "YOURLandingPage.DOMAIN.com/UnsubscribePage.html" (in Design Studio).
- I would recommend unapproving the original page and creating a redirect rule for your subscription management page with the UnsubscribePage.html url. Then update the verbiage found in Admin to make sure it is clear.
- This will also allow you to utilize th Unsubscribed metric when looking at email reports.
