No thanks.

There are several other businesses that specialize in doing just this, so even if they wanted to continue doing the exact same thing it wouldn't necessarily make sense to continue using their own in-house technology.
That said email is insanely difficult to wrap your head around, I've been doing it full time for several years and don't pretend to be anywhere near close to fully understanding it. So just having experience in the space and having tried out some different approaches to similar problems would surely help a ton.

From the article (10/21/2010): "Rapleaf knows your name, your age and where you live. It knows your e-mail address, your income and what social networks you use. It knows your likes and dislikes. And it makes money by selling much of that personal information to advertisers."

"..Previously he(Vivek Sodera) co-founded Rapleaf, a consumer data company that was acquired in 2013, and spun out LiveRamp, a data onboarding platform."
It would be great to hear what A16Z's position on consumer privacy is, as I am sure this is just a misunderstanding.
At $30 / month for a webclient I would hope it comes with full iron-clad private hosting of your stuff with an strong privacy-based agreement to boot. I pay half that for my mail for a few mailboxes about maybe 50 gbs of storage between them.
Don't get me wrong, it works well for what it sets out to do, and the stagnation is understandable given how Thunderbird was always treated by Mozilla as a sort of red-headed stepchild before they cut it loose altogether. This is a project that has been operating in survival mode for a long time now. But it does mean that there is space in the market for an email client with a modern UI and some fresh ideas on how to interact with email.
That's something Outlook and Thunderbird don't do, is give you convenient features to hide information. Sure, you can organize things into folders or labels, colorize things for follow-up, sort emails, etc., but you're fundamentally limited by their model of "emails should be in a list, like a database. And they should be in chronological order. And you deal with them in chronological order, or you colorize them."
