The "study" says that "nearly 20 percent of email does not get delivered toMy experience with running an anti-spam service is that 20% is probably not far off for non-technical end-users. I might put it closer at 10%, but it's certainly larger than you would expect. First of all, they never check the stuff that gets dumped into the spam folder in their app or service--so the filters don't get fine tuned. Secondly, they ignore legit bounces (heck, gmail flags all bounces as spam). Thirdly, they tend to delete anything from anyone they don't recognize--that particularly includes receipts for stuff they bought online, and subscriptions that they knowingly or unknowingly signed up for.
The main point is that even if they've got a spam filter with a low false positive rate, that doesn't mean all legit mail gets "through".
Speaking of bounces. For the past month or so I've been getting daily spam bounce-backs that are from lists very similar to those that I actually subscribe to (i.e. similar technical content). I'm beginning to wonder if the spammers aren't trying to get through to mailing lists that authenticate based on sender email address.
