You need to explain a bit more what you mean by a toolbar, as most toolbars are not much more than a way to get malware or spyware onto your system. Is this a toolbar you used to have and have lost and if so, can you remember the name of it?

johnr is exactly right. Many toolbars open the door to malware or spyware infection. You'd be better off putting a shortcut to your email in Favorites (for IE) or Bookmarks (for Firefox). I don't recommend Chrome.
