For 48 days, I literally tried every autoresponder and listmanager product I could find on the Internet. Dean Wiebe's "ListMail Pro" is the only product that was 1) Suitable for all email marketing needs, 2) Easy to install, operate & maintain with very low impact on the server and 3) low-cost for total ownership and free upgrades forever. Dean proved he would support his product too, because I emailed him to death with questions before I bought ListMail Pro. His replies were always fast, friendly and knowledgeable. With the elegance of a Lexus, the heart of a Ferrari and the price tag of a Buick, ListMail Pro is the top choice for professional email marketers--get it.
