Stop making changes that force things on people
Block addresses no longer works and viewing raw messages only works if you open the email. The whole point to viewing the raw message is to track who the email is coming from WITHOUT OPENING IT!! If it is spam than the spammer knows you opened the email. HOW CAN YOU IMPROVE? Stop forcing things on people!!! As you can see by all the feedback, few people wanted these changes you have imposed against the will of the people.

Hi there,
To view the raw message without opening the mail, check the box next to the message you wish to view, then click on the ellipsis (three dots) at the top of the message plane (next to “Spam”. From the dropdown menu, select “View raw message”.
Thanks,
