I think this is something that sucks about your particular sorting facility or you're just very unlucky. I've been using Informed Delivery since it launched, in two different states, and while it's not perfect, I find it pretty accurate, especially for normal mail (envelopes, postcards, and so forth). I'd guesstimate that it misses a real non-junk mail item less than 1% of the time, and it misstates when something will be delivered 5% of the time or less. Certainly not enough to offset the value of the service.
