I found a fix for my issue. After debugging the problem I got to know that the server removes the UTM marks if they are connected with the URL via ? like this: ?utm_source=follow-up-email&utm_medium..
But if I use # to connect the URL with the UTM marks I can see these UTM marks are added correctly to the page: https://prnt.sc/LW7O4lONXFpU 
To do this, I added UTM marks directly to the abandoned cart template: https://prnt.sc/M0Qy-RJK67k1 
I hope this may help someone!
