In the "Members" section of the platform settings, click on 'Sending an invitation to all non-registered users'. By non-registered users the system means pending and drafts users.

When you click on this link, a window invites you to write an invitation text that will be included in the email.

💡 Note

You can also (re) generate an invitation in real time to draft or pending users, by clicking on the Options to the left of a user on the list.
