Slack now lets you DM anyone
Slack is starting to roll out a new feature that lets anyone using the service DM each other. Announced back in October, Slack Connect DMs will let Slack users privately message employees outside of their company. It’s designed for companies working with partners or clients, but you could even use it to message friends at other companies.
This new DM feature builds on Slack’s work with Connect, which started appearing last year. Slack Connect is primarily designed to let businesses collaborate together through shared channels, and cross-organizational DMs is the next big part of Connect. DMs work by sending a special link to start a conversation and may require Slack admin approval depending on how your organization has set up Slack.
