I do just that with mutt. To add notes to an email hit 'e' and it fires up the raw email in emacs (or your favorite editor). Just add comments and save it.

Mutt doesn't have a fancy UI but it is fast. It has no problem handling the 150k+ in my inbox (mostly unread). I know some people that swear by pine and for all the same reasons. YMMV.

Most UI problems are a lack of interoperability. All solved with emacs and flat text.

Most of your UI problems are a lack of interoperability.

In terms of capabilities that users want, I'm right. In terms of making the UI intuitive for the common user, obviously my solution isn't the answer.
