One way to attract people who hate ads to subscribe to your site is to create two versions of your e-zine. This will give them the choice of ads or not. You can also publish you e-zine only on your website and then have visitors subscribe to an email reminder for a new issue.
You can also offer weekly or a daily visitor bonus as this will create repeat traffic. Your visitors will return again and again just for a chance at the bonus because everyone likes free things. Another way to attract more internet sales is to sell space on your site like fliers, booklets and digital ads for electronic products.
You could make part of your site just for members only. In this way you will trade the access charge into a free bonus for whatever it is you are selling. Another thing to try is to allow visitors to download software at no cost and just ask them to mentions your site to their friends. One good action will cause another.
