I have mail that is coming in that I don't see in my inbox but when I look at "All Mail" I see it. How can I tell why it is not in my inbox or what labels have been assigned to it. Any way to tell what rules got applied to that email so if I have a bad rule I a can fix it?
To view all the labels assigned to an email message open it. All the assigned labels should be displayed below the subject.
To find which filters applied the labels and archived your message you should go to Settings > Filters and analyse your filters.
