Whatever you offer - make sure it is Free. The quickest way to build any list is to give away free valuable content, information, videos, reports, ebooks, discounts, prizes... everybody loves a free gift. Just make them an offer they can't refuse.

Some marketers argue that giving away free items will attract the "wrong kind" of customer or subscriber --- people that will never buy anything because they will expect it to be free. But this has more to do with the nature of your gift and the kind of contacts you're building; giving away free buying guides on how to purchase real estate, fast cars, LCD TVs, laptops... will definitely attract the right "buying customer". If you're into selling, you just have to adjust your marketing to incorporate the free element correctly.

Besides, giving away something free is the first step in starting an ongoing relationship with your subscribers. It gets the ball rolling. It is one of the most effective ways to build your list quickly and easily. Just make sure you're giving away something of value to the person receiving it and they will turn to you, time and time again, to find what they're looking for on the web.
