Drew Houston & Arash Ferdowsi:
To our Carousel and Mailbox users, thank you for embracing these products—and we’re sorry. It’s not easy to say goodbye to products we all love. But ultimately, we think this increased focus will help us create even better experiences for you in the months and years to come.
I never used Carousel, but I was always a big supporter of Mailbox and hoped that one day they would transform it into what email could and should have been. While waiting, I switched over to FastMail with my own custom domain — it has been much better than I could have expected. But it’s still not what I want – a combination of Slack and email, which would make life easier.
P.S. FastMail kills Gmail in every regard. It also has Push in Mail.app on iOS for a while now.
