List building is all about connecting with your target audience by offering them high quality information in exchange for their subscription. Once a subscriber is a confirmed member of your list, you can begin sending promotional based follow-up emails in balance with relevant and useful content based on your overall market. Email marketers (like you!) collect leads using a combination of squeeze pages and opt-in forms. These forms are generated by your autoresponder provider and are embedded into the HTML code of your squeeze page template.
Each time a visitor to your squeeze page enters in their name and email address, they are added to your mailing list database and become an active subscriber of your newsletter.
