By default, people need an invitation to join a Slack workspace. Workspace owners can approve certain email domains so anyone with an approved email address can easily verify their email to create a Slack account.
Note: Enabling single sign-on (SSO) will override your workspace sign-up preferences.
Set your workspace-sign-up mode
From your desktop, click your workspace name in the top left.
Select Settings & a dministration from the menu, then click Workspace settings.
Click the Settings tab.
Next to Joining this workspace , click Expand .
Choose how people can join your workspace. If you select Allow i nvitations, and approve invitations for any email address from these domains, add approved email domains in the text box.
Click Save. Anyone with an approved email address can join by clicking your workspace's sign-up link.
Tip: If a member of your workspace requests an invitation for someone with an email address on an approved domain, the request will be approved automatically.
