So of course you don’t know the most used web-mail services let you configure an external account on them to receive and send e-mail…? And you don’t know how to set a Speed Dial entry for the web-mail either…?
Again you can still do this with a standalone e-mail client, you haven’t cited a reason why having it integrated into the browser is needed.
Hector please pay attention, the e-mail client wasn’t deleted. The e-mail client didn’t exist in a way to be able to run on top of Chromium, it’d have to be completely remade and there’s no enough market for this “integrated e-mail client” thing to be worth to the devs. In fact it shrinks everyday more because of how web-mail gets better, people check e-mail via mobile devices or use other clients some even included in the OS (OS X Mail, Windows (various) Mail app), etc.
