Astro

Astro is a modern email and calendar client powered by artificial intelligence, and built for people and teams. With Priority Inbox, Unsubscribe, Mute, Snooze, Send Later, and Swipes, managing your email is simple and fast.

Astrobot helps you declutter your inbox and makes sure you don’t miss the important stuff in your day. It tells you when to unsubscribe and when to respond. Astrobot is the first chatbot built into an email app, currently recognizes hundreds of questions and comments, and is getting smarter everyday.
