My install of Mautic is new so I have the advantage of creating contacts when I build test forms to go with test campaigns. Since I have only about 3 email addresses, I will just remove a contact in Mautic when I want to use that contact after I have updated my campaign.
I noticed that though the user was deleted, when I bring them back again all of the past time-line for them remains.
Maybe there is a better way to test than using the same 3 emails … but if not, how do I get rid of the history of a contact?
I am not sure, but when you delete a contact, the IP associated with that contact is kept along with all the browsing history. This would explain why when you add them back, the history is re-assigned to the conatct associated with the IP.
So try deleting the contact AND deleting the anonymous contacts and see of that works.
