Slack has taken another step in its efforts to replace email, adding the ability to send direct messages between users in separate organizations.
The company has been pushing the concept of intercompany communications for a while, first with the introduction of shared channels in 2017 that lets two companies create chat groups for shared projects and more recently with the launch of Slack Connect in June.
The product of extensive re-architecting of Slack’s underlying technology, Connect essentially expanded the reach of shared channels, with support for conversations between employees at many more organizations. It’s an approach that has proved popular: there are now 56,000 organizations working in Slack Connect using 100,000 shared channels.
