For most people, email is a place of online bills and receipts; a digital junk drawer of sorts. For a select few, it's their job. Superhuman is a new startup focused on helping email power users. Currently invite only, the service's desktop app has a keyboard shortcut for everything, stores your data on-device for blazing fast response times, and ties in info from social media so you'll know more about the people you're talking to. It also offers undo send, uses AI to triage and bring your most important messages to the top, and has read statuses so you'll know when your recipients read your mail, click your links, and open your attachments. You can join the waiting list now, but be warned: there are at least 100,000 people ahead of you.
