Old; one box to click to check all new emails and then a box to mark as read. New; no way to check all the emails.
Most of us aren't going to click each email box so we can mark as read, or trash etc. You need to put the Check all box right at the top. And then options to Mark as Read, Trash, Spam etc.

Yes, once you click on one checkbox, a new one will appear at the very top. From there you can Select All and either Delete All or even mark as unread. Thanks!
