I recently set up my primary Gmail account to serve as a central hub for a number of my old addresses. I added a number of filters to apply labels and force most messages to bypass the inbox.
I've noticed that I've been missing some of the emails forwarded from my old accounts. They are skipping the inbox and appearing in "All Mail" with no labels.
I'd imagine that one of my filters is forcing these messages to skip the inbox, but it seems odd that they are not getting a label as all of my filters are set to add a label.
I know I can see all filtered messages by going into the settings tab and editing an existing folder, but I was wondering if there was a more direct way to see what filters were applied to a given message.
It almost seems like Gmail is archiving every message that does not meet any of the various filter criteria.
I found the problem with my filters. My central account was set up to import emails from 5 addresses. I wanted to simplify the filter process, so I created dedicated emails for social networks and for gaming logins.
Rather than creating filters for emails from several places, I could create a single filter for emails to the social/gaming address. I did the same with my two work emails and my old personal email.
When importing my old personal email, I set the import up to skip the inbox initially because I knew all existing messages would come in as unread. I didn't want to clutter my inbox while I was setting up the filters and running the initial import.
By the time I finished setting everything up, I had forgotten about this setting.
To fix the problem, I had to edit the import settings for the address in question and turn off the option to skip the inbox.
I should have thought of this sooner.
