Best practice for copy/pasting into Rich Text Block in CMS?

Design help CMS

Hello, I’m managing a blog for a client and having to reformat each time.

When the client emails me their content, I copy/paste it into the CMS, but none of the heading styles or lists are carried over. Currently, the client writes articles in Evernote, paste to me in email, and I paste it into the CMS and have to reformat

Is there a tool I would recommend to the client to write articles in that would keep the heading/lists info for me?

This would save a lot of time.
Thanks!

I have a client that has had good luck using https://dillinger.io/ 's html text window. They learned markdown and life is better for them.
