This software tool lets you know when a mail has arrived along with some essential information about the mail.

Mail alert lets you set up alerts for incoming mails. You can customize the alerts, if it will play a sound, how long the alerts will remain on etc. Unlike the Outlook alert, which alerts you on every mail coming into inbox, you can set alerts for mails that go into specific folders based on rules set up. You do not get too many alerts, nor does the important ones get lost in the clutter. You can mute off the alerts entirely too. If a piece of mail is already read or has been deleted, the alert will recognize that and will go off, even when the alert duration may not have been over. The look and feel of the alerts in the system tray notification area also can be customized by the user. Full control is available over the color, font, glass effect and transparency of the alert windows.

That this looks like a lot of convenience and a lowering of hassles is kind of borne out in actual usage. You will not need to switch to Outlook every so often to make sure you do not miss an important mail. Many of the actions are directly available through the alerts themselves. Particularly, really important mails can draw your attention through alerts- set for them through the Outlook rules. The alert muting can be a boon when you are working on something important. The message in the alert could be in any of several different languages. This is really a good tool to have around.
