Slack, one of the most popular apps for workplace communication, announced on Monday, September 24 that it's acquiring Astro.

Astro is an email client that launched back in 2015 as a solution for people that wanted to make sense of their inbox with genuinely useful features. One of the highlights of Astro, the Astrobot, added AI to the mix so that it was dead simple to archive unwanted emails, add events to your calendar, and more.

Under its new ownership of Slack, the team at Astro will be working to create "the future of interoperability between Slack messaging, email and calendaring." It's unclear what exactly that means (Slack Email, maybe?), but we should be hearing more soon.

As for the Astro app, it'll be shutting down on Wednesday, October 10 across Android, iOS, Mac, its Amazon Alexa skill, and Slack app. New signups are disabled and the app has already been pulled from the Google Play Store.
