I have a view (commerce line item) with HTML (or unformated) list with several fields.
On each field i unchecked "place a colon after the label" but it does not obey that rule. So i added custom CSS to fields and its working. Each label has "strong" html elemement and that is working fine too.
When the order is complete commerce sends email and results are:
Label: field Label: field
html strong tag displays fine.
I have tried with HTMLmail and MimeMail with emogrifier installed.
