A well-targeted list will generate more income. A list of 10,000 is small to many veterans of internet marketing. Some marketers build separate lists of 10,000 or more subscribers for each niche they serve. Separate lists allow you to market a completely different product mix to a different set of clients and earn twice/three... or more times the profits.

The key element in building a highly responsive opt-in list is to focus your marketing efforts on a target group of people. Another word for a target group of people is a niche. The tighter you build the niche, the higher your response rates bill become. Build a cohesive campaign that speaks directly to your intended recipients.

The Internet represents the quintessential instant gratification medium. People love the idea of instant access. When someone opts in to your list, you must supply this instant gratification by sending an immediate follow-up email thanking your customer for opting into your list and also providing the download link for the information. The quicker you follow up with your customer, your relationship with the customer is enhanced.
