### External Contacts
Contacts are used only for communication within projects, e.g., in the distribution list for meeting minutes of a [Meeting](/en/article/creating-meetings-gzt4ee/) or a [Control & Inspection](/en/article/creating-controls-inspections-tlf1un/) and cannot interactively collaborate on the project. The person is not notified that they have been added as a contact in the project. External contacts are marked as "External." 

| External contacts do not have access to the project.

Documents can be sent to external contacts using the "Send Externally" feature. For more information, see the following article: [Sending Documents to External Parties](/en/article/sending-documents-to-external-contacts-1kbwrau/)
