In order to download and run the Gmail Notifier for Windows, you need to be sure that the program is compatible with your Windows operating system. Unfortunately, this program is not compatible with every Windows PC, even the free version. Therefore, you need to be able to download the free version of the program in order to test its features. After you have successfully downloaded and installed the program, you are able to get started by clicking the "Run" button on the bottom right of the screen, and then enter a new name for your account. After you have named your Gmail Notifier account, you can click the "Settings" button and then select "Save Changes." In order to use the program, you simply need to enter a name for your Gmail account and enter a password. When you are done, click the "Run" button, and you will be able to download the program onto your computer and run it whenever you want. The free version of the program works in a similar manner, but it only allows you to add a single email address to your list. However, when you download the full version, you will be able to add as many Gmail accounts as you want to your list.
