Workspace owners and admins can claim and verify domains for Slack Connect using the steps below:

  1. From your desktop, click on your workspace name in the top left.
  2. Select Settings & administration, then click on Workspace settings.
  3. Select Email domains in the left sidebar. If you don’t see the left sidebar, click  Menu in the top-left corner to find it.
  4. Click on Add domain.
  5. In the domain field, enter the domain (or wildcard domain) that you’d like to verify, then click Next.
  6. You'll need access to a domain name system (DNS) to confirm that the domain belongs to your organisation. Follow instructions provided by your domain hosting service to create a DNS TXT record (for Host, use @ if the domain is not a wildcard and _slack-challenge if it is). It may take up to 72 hours for changes to take effect.
  7. After confirming that your TXT record has been added to your DNS, return to Email domains on your Slack admin dashboard.
  8. Next to a domain, select Verify domain in the status column, then click Next. If you'd like to, set your Enterprise Grid org as the primary organisation for Slack Connect.
