Better Email Experience

Has anyone had any work done on the email module. The problem we have is we have 50,000 contacts and interface a lot on email. We need to be able to copy and paste objects and files in the body. We also think the formatting is an issue. Just worn erring if anyone has done any work on this. We have looked at plugins, but they create other issues. We would rather use the email module as it has feature directly related to some of the other modules like Documents module.
