Remember, these people are truly interested in mailing list what you have to offer them, so you don't want to lose their interest right from the get-go. If you do this properly, you'll see return visits from these loyal subscribers. And you know what that means....more sales for you! § Offer a free article about a subject related to your product or service. This is a very powerful list-building tactic.
Subscribers gained from articles are more predisposed to what you have to offer because they practically opt-in pre-sold. Plus, your credibility as an expert in your field has already been established. By offering information, which your visitors will find useful for free, you can get them to sign-up to your list (i.e. "Enter your email address here to receive your Free Guide"). § Give away a series of Free Reports.
If you offer to teach your visitors about something they are interested in, at no charge to them, you will not only be able to build your list quickly, but you'll also mailing list boost your credibility as an expert in your subject. The best way to distribute free reports are via an auto-responder delivery system. You can set it up so your visitors will receive their reports on specified days of the week/month.
