Your software
My PHP version is : 8

Your problem
My problem is : Whenever we send an email including the URL which is saved in


the utm tags do not get an ? appended: /luh6e7vrlqwe&utm_source=email&utm_medium=mautic&utm_campaign=picture-delivery

This happens in

<mj-button href="{contactfield=shop_link|}">

Steps I have tried to fix the problem :
I have rerouted our domain to handle urls with [&.] and replace them with “?”

How can I provide more details?

as a fix, i just change the url to include a /? at the end
