Let's review what an opt-in list is: a collection of e-mail addresses you get from people who are interested in your product, and request to join your autoresponder list. This means your autoresponder messages will not be considered spam, and the reputation of your business will help build consumer confidence and increase sales.

Now that you know why you need an opt-in list, let's talk about how to get one. There are several ways to collect addresses for your opt-in list, and you should institute as many as you can to develop a wide subscriber base.

Free methods: Articles, e-books and mini e-courses

You can not beat free! Though these list-building techniques take a little more time and effort than paid methods, they can be extremely effective in getting subscribers for you. In fact, you may have already done much of the legwork during your market research phase.

Articles
You can write articles pertaining to your topic, or articles that contain some of the information found in your product, and post them across the internet. Be sure the article contains useful information that will pique the interest of your readers and get them to want more. When submitting your articles to other sites for publication, be sure to include your name (and company name, if you have one) and a link to your web site. If you have professional credentials that tie in to your subject, write a brief bio to include as well.

E-books and giveaways/contests
Just as the idea of free list-building methods appealed to you, the idea of valuable freebies will appeal to potential customers. Obtain short, informative e-books on your topic (or write one yourself) from affiliate programs or other internet marketers, and then offer them as an incentive to sign up for your opt-in list. You can also advertise a contest to give away a certain number of your product, chosen at random from people who sign up for your list during a prescribed period of time.
NOTE: Setting limits on sign-up time and the number of giveaways gives people added incentive to act now. This is a technique you may want to incorporate in your autoresponder messages.

Mini e-courses
Developing a mini-course a shortened version of your full product is a great way to increase interest in potential buyers. When setting up a mini-course, break your product up into several sections. Give away a few secrets in each lesson, but not all of them. Remind mini-course subscribers that much more information can be found in the full version of your product, and include links to both your product page and your autoresponder landing page in each section. Plug your mini-course into your autoresponder program and fire away!
