Workspace Owners and Admins can claim and verify domains for Slack Connect using the steps below:

From your desktop, click your workspace name in the top left.
Select Settings & administration, then click Workspace settings.
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.
Click Add Domain.
In the domain field, enter the domain (or wildcard domain) you’d like to verify, then click Next.
You'll need access to a Domain Name System (DNS) to confirm the domain belongs to your organization. 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.
After confirming your TXT record is added to your DNS, return to Email Domains on your Slack admin dashboard.
Next to a domain, select Verify domain in the status column, then click Next. If you'd like, set your org as the primary organization for Slack Connect.
