Adding campaigns to a contact

How can we add campaigns to a contact ? If I go on the contact page, there is a subpanel for campaigns but no button to add campaigns and even if we see in the contacts details that he has been created through a campaign, this same campaign doesn’t show up in the subpanel for campaigns. Then what’s the point of this campaign subpanel if it’s always empty anyway ?
The mail purpose would be to know if a contact has participated to multiple campaigns.
Thanks for your help

I can’t go and check right now, but if I remember this correctly, the relationship is established as follows:

  • add contact to target list

  • make that target list a part of a campaign

(- maybe you also have to send out the campaign)

  • the campaign should now appear in the subpanel in the Contact’s detail view
