My Gmail Notifier on a Windows 7 machine is showing "No Unread Mail." As a matter of fact, though, I have many new unread messages in my inbox.
Opening up my Inbox in Mozilla Thunderbird or Gmail's website works normally, and shows new mail.
What can I do to fix the Notifier?
Assuming you're speaking of the actual Google Notifier application (there's a 3rd party app called "Gmail Notifier") then it's probably because Google dropped support for the Google Notifier at the end of January (2014).
Basically, they suggest you use the Chrome browser instead.
From Google:
Google Notifier Beta is no longer supported. If you want to continue to receive notifications, you can use any of the following alternatives to Google Notifier Beta using the Chrome browser...
...Google thought the same thing, and today quietly discontinued the free tool, which has been around since 2005. Users looking to install the app are now being told by Google to simply install Chrome, which has desktop notifications built in...
Notice sent to users by Google a couple weeks in advance:
Important Announcement on Google Notifier Beta
We are writing to let you know about an important change to Google Notifier Beta. Starting on January 31, 2014, Google Notifier Beta will no longer be supported, meaning the app will no longer show recent emails and calendar events.
Since the Google Notifier Beta launched in 2005, a lot has changed. Smart phones can now notify us of new messages wherever we are, and improvements to web technology enable similar features to be built right into the browser.
If you want to continue to receive notifications, you can use any of the following alternatives to Google Notifier Beta using the Chrome browser:
To see the number of unread messages in your inbox at a glance, install the Gmail Checker Chrome app. To preview new messages on your desktop, go to Gmail's settings and enable Desktop Notifications. To get Calendar notifications on the desktop, go to Calendar's settings and enable Show floating desktop notifications. You can uninstall the Google Notifier Beta by following these instructions.

Gmail Notifier was laid to rest a few days back and thus creating an end to the desktop notification to those who have been using the service. Gmail Notifier Pro which is the replacement for the former one is meant for high-end PC users for example those running Windows 7 or newer due to the system requirements, for example .NET framework 3.5, which is not found in so many PC which are running XP and others.
As a Gmail Notifier user, I really loved the application for its easy to use interface although now its no more but still, there many webmasters have already started sharing what we can term as some alternatives and so far, I am using Popman, the one I got to know after stumbling this thread 3 gmail notifier alternatives to try. To be honest, I like Popman even after only hours of use and am relieved. The best thing to do is switching to an alternative for Gmail Notifier.
As a workaround, you can try this alternative: https://github.com/xps/Gmail-Notifier-Replacement
It is an open-source, free, and very simple replacement for the standard Google Notifier, and aims as being as close to the original as possible.
