What’s happening here? I imported a user, and sent two emails. Both bounced because of unknown server, and DNC has been set. So far everything is fine. Now I see that supposedly this contact has visited my site. How on earth can Mautic know that this is the right contact when the contact has never had a chance to open the email ? Can we trust Mautics’ contact identification ? This seems absolutely and 100% wrong to me. ![](https://files.slack.com/files-pri/T02GEN0Q6-F7MC9NF08/m-magic.png?pub_secret=f960fa0f37) ---
