    I’m thrilled to finally be able to show everyone what we’ve been working on for the last 2 years. We’re re-inventing the email experience to help you email smarter and faster, so you can get more done, and maybe even actually enjoy your inbox. When we launched Firebase here 10 years ago, HN was tough but fair, and I expect no less this time around! I hope you’ll check out what we’ve built and share your feedback. I’ll be around here all day and am happy to answer any questions. Let us know what you think!
