Webform submission tokens in emails
My solution is simply manually typing out relevant labels for each line.
I just use "Custom body" 

For example:

Name: [webform_submission:values:navn:value]

Email: [webform_submission:values:email:value]

Date: [current-date:html_date]

Unless you change your form often i find that to be the easiest way to format it exactly as you want it.
