Emails are frequently used to distribute newsletters, promotional mails, and various other kinds of material. To profit from this type of marketing strategy, you'll first need to build an opt-in list. A targeted opt-in list should include the profile of the email address owner. Here are some basic steps on how to create a comprehensive opt-in list.

1. Create a website. If you have a website, you can invite visitors to register with your website or sign your guestbook before leaving. The days of having to know code in order to create a website are over. Some website creator programs just require you to cut and paste, like that of WYSIWYG (what-you-see-is-what-you-get) software. Many hosting sites offer free simple to use website building software.

2. Set up a promotion or freebie. Offer your visitor something worthwhile in exchange for their email address, name and other limited personal information. Use Limited Time Only offers as an immediate call to action. You want to grab their attention and get them to act. Make the visitor aware that by requesting the promotion or freebie they're also agreeing to receive future emails from you.

3. Set up an easy opt-out option. When people know that they're not locked in forever, they're more prone to check out the offer by opting in. It creates a feeling of control and works on the same premise as a refund policy. Not satisfied, opt-out.

4. Write and write some more. Submit articles, write a press release, post in forums, start blogging, and visit social networking communities for starters. A great way to promote your site is through your signature file and writing quality content helps establish credibility. People are constantly looking for information on the web and when they obtain whatever they were searching for (answer, idea, knowledge) they will often follow links and/or research the author to get further information.

5. Be creative. Partner with a company that has a business similar to your own. Promote offline with a raffle or something and place an email address opt-in as part of the entry form.

Building a targeted opt-in list can take time, money and effort. People who choose to opt-in are usually in the market for what you are offering and thus, sales prospects. Obtaining a targeted opt-in list can dramatically boost your sales, so these tools are certainly essential.
