Missing translation strings

I’ve been working with the Better Sharing IgnitionDeck Addon (super useful, by the way!) and noticed that there are 2 strings in the public facing email template that I can not translate—everything else can be translated through the provided POT file and/or the Better Sharing blocks. The missing strings are as follows:

• Email Subject Preview
• Email Message Preview

I did notice that there were separate string fragments in the POT (i.e. Email Preview, Subject, Message) but these don’t compile/append into a complete translation (it was worth a shot ??). If those 2 strings can be added to the POT, it would be most appreciated. Thank you!
