Love

It really doesn’t do anything magical. It encourages inbox diligence (todo list mentality) and makes it easy to remove myself from mailing lists that only have my email because I signed up with it to be able to recover my password, not receive their marketing nonsense.

So good! Wish it supported more than just Gmail…

I love it, it’s so good. Just wish I could use other email accounts besides Gmail.
