Strange Spam

A spam email this weekend got past TWO spam filters and ended up in my inbox. Most spam is concerning pharmaceuticals or good-looking women or better SEO, gets caught by the filter, and I tune it out. This one slipped by. The subject was a dubious "hello". I opened it, curious as to what could have bypassed both filters, only to discover it was in a language I didn't recognize. Gmail did recognize it, however, and offered to translate it from Croatian to English. Hmm, that's odd. I don't know anyone in Croatia. Here's what the email said, in English:

Make a pact with Satan for riches now! this is your chance to be very rich. Make a pact with Satan now. You'll be the richest person in the world. I am a priest at the alter of his temple and I will guide you through the pact. now contact me for more information and to be rich in 2 days.

First, the Croatian email isn't that enticing. On Easter weekend, would I really make a pact with the devil? Or, really, ever? It's a new tact I haven't heard of- I thought all riches on the Internet came from Nigeria. Second, besides the subject of the email being in English, something in the text of the email makes me suspect that the message was written in English, then translated to Croatian before being sent- what is it?
