When we are just getting started with an Internet business, we are reluctant to mail our list. There is the fear that once we bother them with an email message they are likely to unsubcribe. It turns out that the opposite is much more likely. If someone joins your list and you wait before contacting them, they may not even remember who you are or why they signed up in the first place.
Maintain regular contact with your list, sending them valuable information on your niche topic at least once each week. I now email my list four or five times a week because they have come to expect me to provide them with relevant information, tips and secrets, as well as some offers to make a purchase of one of my products or an affiliate product. You set the pace as to how often you will mail, and then maintain that pace over time.
Remember that your prospect was excited to opt in to your list in the beginning; it is up to you to help maintain that level of excitement over time. They want to hear from you!
