Yikes! I think we may have normal mode a bit too conservative at the moment. We've got a lot more tuning to do.
One thing you can try if Aqua doesn't seem to be "getting" what you're after is to say something like "make this the email," or "transform this into the email I want to write." Sometimes it needs an extra push.
Honestly, looks more useful. Tensorflow embedding projector is pretty limited except for quick nifty visualizations, but it doesn't really inform you much about different clusters of points or why different clusters or hierarchies emerge. From a quick glance, it looks like this library lets you do that.
