Thing is, if you send them out to millions of recipients, chances are that in the end some greedy/christian fool will be stupid enough to try and 'help out' (get rich). Then they get stung for their life savings and wind up on Watchdog crying about it.
Just check the English in these things - least they could do is hire a Brit to word the emails. So far I've had about 30, one from Yasser Arafat's widow herself, and others from prominent people with loads of gold bullion.
I think you should go for it. Or at least email back and ask how to deposit the money, etc.
