Real-World Example
Jane clicks unsubscribe from a campaign email. The portal should verify the signed unsubscribe data, update her email preference, and prevent future optional email campaigns that must respect that opt-out.
Visual Flow
How It Should Work
- It should let consumers unsubscribe from eligible email communications through a safe signed link.
- It should update the correct consumer communication preference.
- It should affect future campaign and scheduled communication sending where opt-out applies.
How It Should Not Work
- It should not unsubscribe the wrong consumer.
- It should not accept tampered unsubscribe data.
- It should not ignore unsubscribe state in campaign or follow-up jobs.
