Yes, I believe they do. But it's not as bad as people think; while they will have your emails or at least likely will, people underestimate their signal / noise problem. I think as often as they're doing horrible super spy stuff, they're drowning in garbage and can't find what they need. Excessive paranoia and Bay Area magical thinking will tend to claim that the NSA can solve this problem by sprinkling magic "big data" sauce on it but it's a really hard problem if you are them.
