I like the opening "If by any chance you are the person who would like to get an extra income-than you have opened the right email". "Than"? Surely "then"? It should, of course, read - "If by any chance you're a gullible idiot, then I think we may be able to con you out of some money".
What is also near is the way that they claim that FIC Ltd is working on charity projects. They're not criminals after all. No, they're not going to make you rich quickly. They're first going to raise a lot of money for the "National Charity Fund" (or NCF) that famous charity that all criminals pay into.
This is a deeply polite email, but just becasue they're being nice, doesn't mean they aren't killing babies or shooting prostitutes or something.
