Thanks for the response Chandan!
You’ve hit the nail on the head with the features. And the intelligence with email that we are building in is something that has interested a lot of people!
The chat feature is something we are debating internally, but of course if enough people ask for it we will definitely build it in :)
We’re in private beta right now, and are working furiously to get everything in shape for a public release. Do follow our publication on Medium to stay up to date with what’s happening! We’ll be making most major announcements here!
