" Is there any possibility to re-design the input to somekind of an understandable way, so the user input values are just not lined under each other when I gert the user input on my e-mail when they have submitted the form? "
Eric, do I understand correctly that the layout of the email is bothering you? If so, changing the input form won´t help: you have to make the data that are sent to the email more readable.
Because there are many email clients out there, all supporting their own subset of html, I would suggest you fall back onto old html (like 3.2) and use tables, you know,
In my experience, steering away from CSS and just use old html tables works pretty good on most email clients.
