You can, but you shouldn’t. It’s generally considered bad form to do so, since this makes it appear as though you’re not really interested in the person you’re emailing. It may also come across as lazy and unprofessional. If you must include your meeting notes in the body of an email, be sure to edit them first. Make them concise and to the point. No one wants to wade through a wall of text, and chances are that your recipient won’t even bother reading it all if you just copy and paste your meeting notes verbatim.
