Personally, I find it hard to constantly check for new emails, especially when I use up to four email accounts simultaneously. InboxAce Toolbar is a small browser tool that has been created to solve this issue and let you quickly find out whenever you receive a new email.
This toolbar is very easy to install and configure, therefore, any user would be able to manage it, even beginners.
Once you finish installing the utility on your browser (Mozilla Firefox, Google Chrome or Internet Explorer), you can start checking your email account with just a push of a button. A built-in search tool makes a good addition to the program by helping you find any information you need on the Internet in a really fast manner.
Still, if you ask me, this browser tool could use some improvements. For instance, there are no Opera or Safari versions, it doesn't alert you with Twitter or MySpace notifications and it often fails to display the new message notifications.
Despite the mentioned flaws, I still consider this application to be quite useful and time-saving when it comes to checking your emails. And, since you don't have to pay to use it, I see no reason why you shouldn't give this browser tool a try.
