False Positives / Areas for improvement
Given the context of sending HTML emails from Salesforce that contain references to currency / money, some minor false positives may occur. But these will not prevent an email from being delivered.
Following the steps in this guide should achieve scores of 9.7 or more. A score of 5 or lower is cause for concern, and likely will not get delivered.
