@moonmehta KTN (kill The Newsletter) works well! Many email newsletters don't have a URL backing them, so KTN shows them as standalone items in my RSS feed. Those that do, point to those.
The formatting is a little barebones. For example, InkMango/thejuggernaut uses a lot of tables in their emails (primarily because their email provider - mailchimp formats emails like that) and those show up as weird outlines in my feed. But others make responsive emails and KTN flourishes with those!
Receving emails is a breeze. I think KTN processes hundreds of thousands of emails and doesn't break a sweat!
The only caveat ever is that you should keep a track of the original email, since it has a code that lets you modify your newsletter settings, not that there are a lot of settings to modify in the first place. You can just copy the code once to backup and be done with it, if you want to bother with it at all.
I've seen Feedbin have a similar feature and that's very nice of them. KTN is perfect for us outsiders :)
