I have finished the change I talked about. Here is where you can set it and forget it.
1. Login to modern view
2. Click Profile
3. Note if you have the right email in the email box, if not, fix it.
4. scroll down and check "Always show my email".
From then on, on both Modern and Classic View, when you post, that post will have a "Send Email" link on it. It will also send reply notifications by email.
