I have found it useful in Live.com circumstances...
After marking enough of them junk, the filters at Microsoft get better and better - usually over a span of a few weeks; but this new "campaign" is taking longer. However, this is the first time, I've seen legitimate product names in the subject line, even though the blocked content always has the same pattern. Maybe MS will realize the body content will be a match, so they can adjust filtering to that. I assume they use some kind of auto intelligence for their filters; they used to be the best.
As far as Outlook goes - I use Avast's spam filter, and it has been one of the best I've used in years.
