Securely direct message your trusted partners

Enable real-time communication by inviting an external partner to direct message in Slack

Why try Slack Connect direct messages?

Ad hoc collaboration is often challenging when working with people outside your company. For example, collaborating on a sales contract or reviewing the latest designs from a prospective creative agency requires real-time communication that isn’t possible over email. 

Now, you can quickly and securely work with your trusted colleagues by sending them an invitation to a direct message in Slack. Reduce context switching between different tools by moving these conversations to the place where you’re already working: Slack.

You always remain in control over who can message you in Slack.

  • Only begin messaging in Slack after you’ve accepted your partner’s invitation
  • If you receive an invitation from someone that you don’t want to message, you can choose to stop getting future invitations from that person

For the most part, direct messages with trusted partners will look and feel just like the Slack that you’re already used to.

To get started, compose a new message and type your partner’s email address to send them an invitation. Once your partner has accepted the invitation, you can begin direct messaging in Slack.
