Slack is adding the ability to direct message users at other companies, with Slack Connect paring back some of the separation between different teams. It’s the latest attempt by the popular business messaging platform – which Salesforce is currently in the process of acquiring for $27.7 billion – to oust email from the office.
Slack became a darling of workplaces well before the pandemic forced remote working to go widespread. Consisting of a different rooms for group discussions, smaller conversations for teams, and individual messaging between users, it aimed to cut down on unnecessary and unwieldy email chains as well as make conversations more real-time.
Slack Connect looks to do that but more broadly. “Designed to replace email outside your company, Slack Connect allows you to work with external organizations with the same speed and security you’ve come to expect with Slack,” the company said today. It’s in part a response to the growing recognition that post-pandemic workplaces won’t look the same as they did before, and that distributed teams are going to need new tools not only to collaborate within companies, but with partner businesses too.
Slack Connect will allow up to 20 organizations to work together in the same space. Each organization taking part will have control over its own data, and later this year there’ll be the ability to link those organizations into a “private business network.” That will include unified directories of contacts, tighter with channel discovery and other features.
The most obvious feature addition will be the ability to send direct messages to someone not on your team. You’ll be able to send a Slack invite to a partner and – once they accept it – start messaging as though they’re in your own company. Slack Connect DM invitations will be expanded to all teams, the company says, including those using free plans, soon.
Perhaps unsurprisingly, the new feature hasn’t been met with universal acclaim. Slack – among other workplace messaging features that put ubiquity at the top of their priorities – has been blamed for helping establish unrealistic work expectations, with employees often feeling they need to be checking their channels and messages outside of business hours. There have also been cases of harassment carried out over workplace messaging tools, and the fact that employers can access chat logs has also been criticized.
According to Slack, there’ll be systems in place to prevent misuse. “Admins can already designate which users or which workspaces have access to Slack Connect,” the company says. “Soon, admins will also be able to restrict the behaviors of members from partner organizations, such as inviting others and installing apps.”
In short, while cross-company DMs may be possible, your admin team will need to enable support for them first, and it’s not going to necessarily be a free-for-all of invitations.
