Slack on Thursday announced a series of milestones it's recently hit, including reaching 4 million daily active users in the month of October. Nearly half of those users are outside of the US.

The company also reported reaching 5.8 million weekly active users, with more than 1.25 million paying users and more than 33,000 teams paying for its services. It's also surpassed six million apps installed on Slack teams.

"Continued momentum on the Slack platform is an important sign of the expanding role we play in the business software ecosystem," the company's blog post said. "When we say 'Slack is where work happens,' we don't just mean people sending messages to one another, but the integrated workflows, business processes, data streams, and applications that spin the gears of work for tens of thousands of our business customers around the world."

While Slack is still enjoying strong growth, some big players are coming for it: Facebook just rolled out Workplace, its enterprise collaboration service, while Microsoft is expected to launch Skype Teams in beta next month. Meanwhile, email doesn't seem to be going anywhere. Slack, for its part, is aiming to stay competitive with its third-party integrations. The partnership it recently forged with Salesforce was a big win, as well as features like Sign in With Slack.
