The GraphicMail extension allows you to grow your mailing list through Magento transactions! Every time someone registers or buys from your online store, ask them to opt in to your GraphicMail newsletter. This way, you can send them targeted newsletters, i.e. notify them of new specials, good deals, or new products.
Note that while this extension is now considered stable, it is strongly recommended that it be tested on a development/staging site, before deploying it to a production site.
