I used to send these monthly massive 'update' emails to all the execs at my tech job. While it's not feedback, at some point I switched to including a TLDR version at the top for the busiest people and a long-form explanation for anyone interested.
I was pleasantly surprised when the CEO gave a huge 'THANK YOU FOR THE TLDR version' in a reply all. The 'bottomline' comment kind of reminded me of that haha.
