In Hotmail.com email, there was a rule that allowed a user to keep the most recent email from any email sender and delete the rest. Or there was one that would keep the last "so many" and other very useful rules. They were great for reducing emails that stay in one's inbox. One wants the ability to read them or ignore them and they eventually disappear.
You seemed to have deleted these functions. Please consider putting them back in!!!
