Invitation limits

In certain circumstances, Slack may limit your ability to send invitations. This typically happens if you’ve sent many invites, but few have been accepted.

If you hit an invite limit, all of your pending invitations will remain valid. Please note that revoking pending invites will not lift an invitation limit.

To avoid hitting an invite limit, create an invite link (or ask your Workspace Owner or Admin to do so) and share it with anyone you'd like to join your workspace.

Who can use this feature?
  • Workspace Owners, Workspace Admins, and members (by default)
  • Free, Standard, Plus, and Enterprise Grid plans
