So I've been using Google Now for a while ands despite the fact that I've gotten several emailed shipping notices for various packages (UPS, FedEx and USPS), I've never gotten a shipping notice card from Google Now like I've seen from other people. Nor did I get notified about a restaurant reservation with confirmation email via Open Table. And I've made certain that the "Gmail Cards" option in Google Now is turned on. I'm thinking it's possibly because I have a habit of reading an email then archiving it (not deleting), so my inbox is usually empty (though all the necessary emails are still on Gmail). Does Google Now only look in the Inbox to build its cards and notifications, or does it all use the "All Mail" box as well? The other thought I had is that some of these verification and shipping notice emails and shipping notices are forwarded to me from other email addresses - so some are technically not addressed to me (just forwarded to me). Does Google Now skip emails not addressed specifically to you (i.e., does it only use emails addressed to you, not forwarded or BCC'd)? I guess I'm looking for some insight on to how Google Now's Gmail cards work so I can maximize its IQ.
