Move the code sent via email to a separate line

Could you please alter the content structure of the email template so the strong was displayed in a separate line?
Now, when you double-click the code there is a whitespace also selected. I got used to it but I need to explain this each time to my websites users when they claim the code being wrong. This is even more inconvenient now, since the input field chars numbers is limited and there is no option to remove a whitespace after the code is pasted n the field.
