Gmail Notifier Pro is one of the most powerful applications for periodically checking and notifying you of new messages in your Gmail, Hotmail, Yahoo! Mail and many others whose mail servers support IMAP or POP. In addition to its basic functionality, it also allows you to be notified of upcoming events in your calendar (Google Calendar), news in Google Reader, news provided through RSS feeds, Atom and Google News, and new entries on social networks such as Facebook, Twitter and Google+.

The tool, like most simpler solutions of this type (e.g. Google Gmail Notifier or Gmail Notifier), periodically checks the content of defined mailboxes and informs about new messages by displaying the e-mail header in a bubble and by playing audio signals. From its level it is also possible to mark selected messages as read, as well as delete them.

Most services are connected to servers using the IMAP protocol, which does not download entire messages to disk, but only their headers. The exception is Hotmail support, which is implemented through the POP protocol. What distinguishes Gmail Notifier Pro from these applications in addition to supporting more email services, etc.

is also richer functionality and the ability to easily configure and customize it to suit your preferences. The tool allows you to send emails without the need to use a mail client or a web browser, download information from Google Calendar and Google Reader services, as well as the RSSSSSS-productsAtom feeds of our favorite websites. Another advantage of Gmail Notifier Pro is its great ability to configure individual aspects of its work - from indicating what time is to be checked for the content of mailboxes, type and appearance of notifications, colour and theme of the graphical interface, to the work schedule.

The free version allows you to support only two accounts. If you want to bypass this limitation, you need to register the program, which involves a one-time fee of 12.95 USD.
