Format of e-mails announcing changed itineraries
 

I just received an e-mail informing me about a changed itinerary:

I almost deleted it as spam due to the odd and completely uninformative header (note that the date in the header is the date of the e-mail, not the date of the flight and that it doesn't say "KLM" anywhere; LASTNAME and FIRSTNAME were my correct last and first names). English grammar is also not a strength of this e-mail.
