Almost all the mails I find in Google's spam filters are false positives, including Fidelity mailings and many legitimate mailings such as e-newsletters. My gmail accounts get virtually no "real" spam, but Google seems to program its filters to catch something. Mostly it's press releases, some of which do look spammy, but as a journalist I need to receive some of them. But it could be any mailing that meets Google's spam criteria, including a series of rapid-fire emails back and forth or routine administrivia like dental appointment reminders. (Interestingly, it has never flagged LinkedIn notices as spam.)
If you're missing something important, check your Gmail spam folder. You may be surprised.
