Contact form submission: Styling is askew

This is in regard to the format/layout of the fields in the emails that are sent when forms are submitted. The problem is that the field name columns are not very wide. I’d say they are shrunk way too small, and it’s really bad styling.

In the Settings for this plugin, the Field labels tab is the only section that I think could control the format of the email. However, I don’t see anything that allows for HTML, or any other way to control the view in the email.

I would attach a screenshot, but I cannot. All I can say is that the Name, Email, Subject, etc. – Field names – are not given enough space to breathe, so they are being carried to the next line, like this:

Subj

Where or how can I change this?
Thanks
