My messages skip the inbox
If your incoming messages are skipping your Inbox, the cause is a misconfigured filter, or a setting on your Forwarding and POP/IMAP tab.
To resolve this issue, please make sure you haven't created any filters with the actions Skip the Inbox (Archive it) or Delete it that would affect the messages in question. If you have many filters or have complicated filters in place, you may need to edit the Skip the Inbox (Archive it) or Delete it action to guarantee that they are not at fault.
If you've enabled forwarding in your account, please ensure that you have not selected archive Gmail's copy or delete Gmail's copy in your forwarding options.
If you're using a POP client to access Gmail, please ensure that you have not selected archive Gmail's copy or delete Gmail's copy in step 2 of your POP download options.
Finally, if you're accessing your Gmail from multiple POP clients (with recent mode), please verify that you have selected 'Leave a copy of messages on server' in your client configuration settings.
