With HTML emails that contain #anchor tags to places in the same page: the anchor tags do not work in the Notes client. Actual URL hotspots work fine, just not the anchor tags. They work fine in iNotes though.
Have you asked in the ND7 Beta forum? The tech issues were already explained – there is no work-around. A “fix” (and there’s a difference between “broken” and “not implemented”, so this isn’t a fix – Notes doesn’t display HTML) is more likely in the new code stream.
