Invite new members to your workspace
By default, members (but not guests) can invite new members to their workspace, but owners and admins can change this so that invitations require admin approval. If admin approval is required, members can request invitations for admins to approve or deny.

Send an invitation
The ability to send invitations depends on your role in Slack, as well as your workspace settings and subscription. An invitation will be active for 30 days after you send it. Owners and admins can resend a pending invitation to reactivate it.

Share an invitation link
On the free, Pro and Business+ subscriptions, members with permission to send invitations can also share an invitation link. Each invitation link is active for 30 days, and can be used by up to 400 people. If your invitation link expires, find an owner or admin who can manage invitation links in Slack.
Bear in mind that anyone who clicks the link will be able to join your workspace. To safeguard the privacy and integrity of your workspace and our platform, make sure that you share the link securely, and only with those who should have access to the contents of your workspace.

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. To avoid reaching an invitation limit, you can share an invitation link instead.
If you hit an invite limit, all of your pending invitations will remain valid. Please note that revoking pending invitations will not lift an invitation limit.
