I loved sparrow, bought sparrow. It got acquired and went away. I loved mailbox, used mailbox. It got acquired and is more and more unusable with every "update". I would love to love this, but I've been hurt before.
We're here for the long haul! Looking to solve problems with more than just Mail Pilot, too - check out Throttle (https://throttlehq.com) for example.
We'd be happy to answer any questions you have.
On a side note I built something like throttlehq back in 2009. I even made one of those zany animated how-it-works videos that were popular at the time. https://youtu.be/SLJHPMxgAWU?t=14s site is down, but here's the source https://github.com/schneems/WhySpam. It didn't work out so well.
Around the same time another company called OtherInbox had a really similar product. They've shut theirs down due to lack of monetization.
I like the button right in the form with the extension, that's a nice touch.
However, I think the major pain for me is getting control of my current inbox. Just getting an overview of who has my email, who sends what and how often, is extremely hard.
Secondly it would be difficult to choose who to give my throttle mail and my real mail address to.
I don't want the Amazon spam mails, but I still want to know what to type when I log in to their website.
Other, trickier, problems I don't know how to solve:
I want updates from my coursera course, but not from coursera. Actually that's the same with Amazon: I want them to send my receipt, but not the monthly/weekly spam mail.
