The number of extremely useful business opportunity tools that are available online for free is amazing and the sad thing is that many are hardly put to use by many including a particularly powerful one from Yahoo.

I am referring to the Yahoo groups program, which is a wonderful online business opportunity tool that can make a huge difference in the performance and efficiency of any business. There are numerous businesses that have already greatly benefited from using Yahoo groups even as many others remain in the dark. The program is free and is financed by some very limited ads that go out with all your mailings and messages. But this does not stop an email marketer including their own ads in the messages that they send out.

While it is true that other major search engines have also recently launched similar tools, the Yahoo groups remains in a class of its own in terms of what it can deliver and the sheer experience of being the premier and largest free email service provider.

Yahoo groups can be used for many different functions and applications but for the purposes of this article we shall concentrate on one. And that is the distribution of an email newsletter and full management of an email opt-in list.

No serious online business opportunity can be taken full advantage of without an email opt-in list and the Yahoo groups program is capable of fully managing and delivering email on a regular basis to a large list very efficiently.
