This is an off line method of building your list, but you will be driving traffic to your web site, where your prospects can sign up. You will achieve best results if you can find a newspaper or magazine whose readership is your target market. For example, if you were a matchmaker you could place a classified ad in the “Personals” section of your local newspaper.
Bonus tip: Start small (i.e. cheap) to polish your ad, then work up to display ads which are more expensive.
Make sure you track the effectiveness of each of these marketing techniques. I recommend you use ad-tracking software, which allows you to assign a unique “ID” to each article, listing, or classified ad. This way you will be able to track your subscribers, see where they are coming from, how many are converting to clients, etc. This kind of information can help you eliminate marketing strategies that do not work, so that you can concentrate on the ones that do.
If you’d like to add ad-tracking features to your existing Email System Provider, I recommend HyperTracker.
