Speed up communication and work more securely with external partners, vendors and people outside your company

Why use Slack Connect?

Designed to replace email – or however you collaborate with external organisations, customers and clients – Slack Connect makes the work that happens with outside partners faster, more productive and more secure.

    reduction in weekly meetings for a technical team working with third-party contractors

  • 2x

    decreased turnaround time for creative reviews and approvals for a marketing team and creative agency.

For the most part, working in channels or exchanging direct messages will look and feel just like the Slack that you’re already used to. But in Slack Connect, you’ll be communicating with stakeholders from different companies. Everyone can discuss work, share files and drive business results in a shared space.

We hear back from our customers that we’re like an extension of their team, and part of that feeling definitely comes from the fact that we use Slack.

How to get started with Slack Connect

Just like with Slack, you can choose to either use direct messages or channels to communicate.

  • If you are working with one other person – on a contract or proposal, for example – send them an invitation to a direct message. You’ll be able to start messaging in Slack as soon as your partner accepts.
  • If you need to work with more than one person – perhaps on a longer-term initiative or campaign – you can send an invitation to collaborate in a channel by following the steps below. Depending on your settings, the invitation may need to go through admin approval.

1. Create the channel

Click on the + button next to Channels in your sidebar. Name the channel, select privacy settings and click on Next.

2. Send the invitation 

Follow the prompt to share the channel outside your workspace. Send your partner an email invitation right from Slack.

3. Wait for your partner to accept

Stick the kettle on. When your partner clicks on the link, they’ll be taken back to Slack, where they can accept the invitation and set up the channel on their end.

4. Get admin approval

Depending on your settings, the invitation may be sent to an admin on each team for approval. Admins can manage channels invitations by clicking on their workspace name > Administration > Manage shared channels.
