Astro launched in March with the goal of cleaning up your inbox using an AI assistant. It’s an interesting, if not perfectly convenient, way of managing overflowing inboxes that’s meant to make life easier for business users in particular. And today, Astro is getting two new features that push its credentials for business users even further: integrations with Slack and Alexa.

The Slack integration is particularly neat. Once Astro has been linked to Slack, any searches will pull up results from both your inbox and your Slack channels. I suspect this could make things very messy, since Slack searches surface conversations you were never even a part of. But I like the idea of integrating an email client with the service that’s supposed to — and in some cases does — kill email.

You won’t be able to reply to Slack messages directly within Astro, but you will be able to tap on search results to jump straight to the conversation in Slack. And you’ll be able to take emails and embed them in new Slack posts, so that you can move a conversation into Slack. Andy Pflaum, Astro’s co-founder and CEO, demoed the integration for me during a meeting earlier this month, and it all seemed to work pretty naturally.

Astro is also bringing its AI assistant, Astrobot, into Slack itself. It’s another way of combining email and Slack, with the bot pinging you occasionally with items that might need your attention. You’ll be able to respond to emails directly within the chat window, without changing over to Astro itself, which is pretty handy.

Unfortunately, there’s one big hiccup that I encountered while trying to test these integrations in a pre-release version of the app: you need administrative permissions in order to hook into a Slack account, and my company doesn’t grant me that level of access. I suspect a whole lot of people will find themselves in this situation, which means that Astro’s smart new integration won’t get used unless you have a very trusting IT team. Or, as Astro is hoping, a company that chooses to widely adopt its software.

The Alexa integration, on the other hand, should be entirely doable on your own. (Assuming, at least, that you aren’t trying to hijack someone else’s Echo.) Once it’s set up, you’ll be able to ask Alexa to read your recent emails and even respond to them with quick replies. The system can be locked up with a PIN code, so that other people can’t access your inbox just by asking.

Pflaum wouldn’t disclose how many users Astro has gained since its launch a few months back, but he says that the company is “very pleased and confident” so far. He also says that Astro plans to continue adding new integrations, mostly focused on the needs of business users — so think basics like calendars, but also specialized apps like Salesforce CRM. A Windows app is in the works, too; Astro is already on Android, iOS, and macOS.

Everything that’s currently in the app will remain free, but Pflaum says Astro will eventually begin charging people and organizations for “more advanced versions, especially around ways that teams can collaborate and share information.” I suspect Astro and its AI bot will have to get a lot more advanced, proactive, and just generally helpful before big organizations consider paying to use them. But for now, the free version is a unique alternative for anyone in desperate need of help sorting through their inbox.
