Non-static cookie names in Mautic (vs. Cookie Consent Manager)

Basically a repeat from this unanswered thread Random Cookies in Mautic

Mautic is setting various cookies like mtc_id, but also two that have unpredictable names:
a) cookie name =
b) cookie name = some long hash that is persistent for the Mautic instance

-> Those cannot be handled by consent tools such as CookieBot.


  • Can the behaviour be changed?
  • Are those cookies necessary / what will break if they are blocked?
  • What is the general background to begin with?
    Can’t find any hints in the forums etc., nor in the source code.

Thank you very much in advance!
