Admins on Professional, Business, or Enterprise accounts are able to restrict invitations to users with a certain domain.
Using this feature will restrict all new user invitations on your Wrike account.
Adding approved email domains means that invitations can only be sent to people with an approved email domain. To allow invitations to anyone, regardless of domain, don't add email domains.
