I am using mailchimp to manage invitations for the beta launch of a web site. I have a list for people that have requested an invitation and would like to move them to another list when sending a campaign that includes the invitation so we can track who has been sent an invite.
How can I configure mailchimp to move people from one list to another list? Or is there a better way to manage the list in order to avoid sending an invitation to the same person more than once?
